A Massive T.rex Bigger Than Scotty! E.D. Cope: The New King
Вставка
- Опубліковано 2 лип 2024
- How big was T.rex? New data shows that the T.rex E.D. Cope, the "Copium rex," was the biggest theropod ever found, increasing theropod size limits to new heights. T.rex was a powerful predatory megatheropod. While Sue and Scotty are currently cited as the biggest T.rex specimens, new measurements of E.D. Cope, from the Black Hills Institute in South Dakota, form a challenge for the title of the megatheropod king. Measurements of this new T.rex femur indicate that Cope may be between 10.6 and 12.4 tonnes, making it the biggest theropod by up to 2 tonnes. T.rex size is a hot debate in paleontology, and Cope just turned it into a bonfire. Copium rex!

Please see this community post for an update on Copium rex's mass (he's still the biggest T.rex discovered, but not quite as big as this video calculated. I received actual measurements from Peter Larson that changed his size).

@@ahmadfaizan5173 The new estimate is based on the average of different parts of Cope's skeleton compared to other Tyrannosaurs and scaled, and since Cope's limb proportions seem unusual compared to those of other Tyrannosaurs, scaling this way would also have a large variation. The final result taken is the average result of this method. It's a reasonable estimate, but it also doesn't mean that the original estimate in the video was wrong. You can think of these two results as the Cope weight range
I have a suggestion, maybe you can update your weight estimate. Because your calculation seems to ignore one factor, your final calculation is the average of three averages.However, statistical weight coefficient was not taken into account, because for the estimation of body weight, the weight of the three factors in the calculation should not be equal, because they correlate differently with body weight. And the correlation between femur circumference and weight is higher than the other two. So it should have a larger weight coefficient in the calculation. So your final calculation should be the weighted average of the three different averages, and the circumference of the femur should weigh more than the other two factors in the calculation to get a more reliable calculation. If you do not consider the weight coefficient, the final result is likely to be low. Based on this, I would say that Cope over 12 tons is still reasonable, especially considering that the incredibly large tibia may have made its hip height higher than originally expected
I have re-compared the femur photos of Cope with those of Sue. The femur of Cope shows slight but obvious signs of damage at the femoral head and the lesser tubercles of femur. Perhaps we should re-confirm with Larson whether 127cm is the pre-repair or post-repair length .This information can be misleading if not clearly confirmed. Although the wear on the picture is not serious, it may only reduce the overall length by a few centimeters, and the repair should be very close to the length of SUE's femur. Of course, even at this length, the femur length is still short compared to the 630mm femur circumference, but the overall hind limb length is still very long. Of course, there is another possibility that Paul's 130cm is the length after repair predicted by him. In fact, he may not have made a wrong measurement, but just recorded the data after his own repair. so I think we should be more careful before we confirm the details and measurement standards
Imagine if EDCope femur was shorter and had a longer tibia. Like the variations between humans , Bolt vs avg Joe's legs. He could be considerably faster and larger. Meaning it might be a naturally swifter variant able eat a larger range of prey as it grew.

Huge prey helps
There's a reason Hell Creek earned its name.
I truly believe that dinosaurs, like crocodilians, continued to grow throughout their lives. A T.rex, so long as it lived long enough, could have probably reached some truly astonishing sizes.
They do grow forever but at some point the growth becomes insignificant as it slows down
This is why I love playing Beasts of Bermuda. It has that as a important part of the gameplay. The older you get, the bigger. But your growth becomes less and less noticeable yet noticeable enough to younger members of your species. Sickness becomes a greater risk the older you get, which holds true even to this day. And the bigger you are, the more you need to consume to fill your stomach.
Not to mention bloodlines, and through a Skilltree like manner being able to focus on survival; eating rotten corpses/less affected by sickness,etc, health, stress reduction.
Combat: which is mostly self explanatory.
Or Speed. Which between combat can also include aquatic/swimming abilities, stealth, & acrobatics capabilities like jumping, turning, etc.
It can really feel like you are growing a dinosaur, especially if you started in a Egg. See yourself develop as a embryo, Hatch as a tiny or small defenseless or sometimes scentless individual. Inheriting things from your parents, be it for good or bad. As inbreeding is a thing and affects you like it would in reality. Pigmentation disorders from Albinism, Melanism, piebald, erythrism, to even xanthochromism and many more.
It makes me wonder if there were, and if so what a real tyrannosaurus rex with erythrism would look like. Strawberry colored? Light pink? Or deep reds. If it affected them negatively in socializing or hunting.
@@boi9842nope, T. rex was an active hunter, cope, pathetic Neanderthal

I am super-masterpiece-34, I think, in addition to raising the upper limit on the size of Tyrannosaurus rex, the presence of these giant specimens shows that specimens the size of sue and scotty are not as rare as people used to think
Do you think that could be attributed to fossil preservation bias, since larger bones are easier to find and are less brittle?
From the geological sense, I think there is no basis for this argument, is it possible that the strata will selectively crush small fossils? In fact, the most complete dinosaur specimens we've ever found are the small ones@@heeheeyup35
@@heeheeyup35I always thought larger animals were preserved poorly?
@heeheeyup35 that's the coolest part of this to me. We won't be done finding fossils for awhile so we still have plenty left to find out.
@@chazparr6132 and @heeheeyup35
Preservation bias does vary from place to place. Like the places over in chine where all the good feather fossils are from, there is a huge bias towards tiny creatures.
In hell creek there is more of a bias towards larger creatures.
However, laws of statistics says that in a normal distribution population we are most likely to find the average of we pick at random.
Meaning the odds of us finding the biggest to ever exist, is essentially zero. But with how many we have found, we likely have seen some in the higher ranges.
T Rex every time a "bigger" apex predator is found: Hold my femur.
I can't believe that a heavier rex was in a paper that everyone forgot about. Also, a possibly heavier (and maybe longer than "Scotty?") T. rex specimen might be around the corner!
True true! I'm definitely one of those people that missed Cope's measurements because I thought the paper was questionable haha. We'll see if Bertha can match up!
@@TheVividen T. rex is demonstrating why it shouldn't be overlooked anymore in the "biggest theropod ever" discussion 😄
@@EBLazerRexshouldn't be overlooked??? Since a while that T Rex is known to be much heavier than the next runner ups for the title 🤷♂️
@@TheVividenThe femur being shorter doesn’t cast some doubt on the 12.5 t estimate ?

Bone crushing bite
@@ZombieSlayer-dj3wb Crushing? Your thinking is too small, it wouldn’t crush bones, it would splinter and pulverize them.
@@julianfalken8861 Well they were also one of the last dinos alive, so older specimens are probably lost/rarer
Remember when WWD thought T.Rexes were only 5 tons? Times really have changed.
Looking back, 5 tonnes was just plain silly, even at the time. I mean, I'm pretty sure the estimates for an average Rex were at 6 tonnes at the time, with Sue being 6,4. It's also weird that they upscaled a bunch of animals such as Liopleurodon and Ornithocheirus (which I believe goes by Tropeognathus now), and the lizard King himself got the lightweight treatment, though they gave it a greater length at 13 meters.
@@devilman4018 Liopleurodon makes sense because they initially only found its head and we didnt know much about Pliosaurs at the time so it was massively overscaled.
Since then a more complete specimen (from a different pliosaur species i don't recall the name of 😅) was found and they changed how they did their measurements and its size shrunk drastically to what we believe to be factual about them now.
As for Ornithocheirus is actually a real species and is closely related to the Tropeognathus but Tropeognathus wasn't described at the time so I believe they treated it as maybe some form of subspecies based off fragmentary remains? That one always confused me a bit tbh it is massive even by Trope standards
5 tons even a midget t.rex wasn’t that small
@@GODEYE270115 Right? Maybe a Tarbosaurus. But a fully grown T.Rex? To this day I still don't know where those estimates came from. WWD is a solid series, probably my favorite piece of dinosaur media out there but the final Cretaceous Episode had some flaws that were inaccurate even for the time. The idea that dinosaurs were dying out prior to the meteorite was one of them.
@tossupeater While I remember there being estimates at the time that suggested Lio getting that big, I also remember the producers saying they made it that large for dramatic effect. As for T.rex, it honestly wouldn't surprise me if the animal is actually 13 meters instead of 12.
Looks like Scotty has possibly been dethroned.
Just like how he dethroned Sue all those years ago.
Can't wait to hear a 15 ton Rex when I'm at my deathbed.
Almost certainly existed at this point
T. rex gets more badass with each new discovery. The attempts in the 2000s to have it being outshined by Spino and Giga look now hilarious. The King was always there all along.
Exactly
And also Carcharodontosaurus. That lad was also estimated to grow past 15 meters & 15 tons. And it's now lighter than a T Rex
@@MonsterZilla452 True, but Carcharodontosaurus wasn't used to crush T. rex and be shown as the new big bad theropod in town (unless you count Dinosaur King lol).
It won’t stop, I hate it, I don’t like how pop culture always think that to make an animal interesting they have to be a t. rex killer, Instead of just, Being itself! It makes me angry.
Agreed. But I still wish for Spino to be big, because I love it :D
Now imagine the bite force of this thing. This is why T- Rex is my favorite prehistoric animal. They pushed their body to absulute limits as far as laws of physics allowed it. These animals were literally desinged for endless combat. But when you think T- Rex barely could survive in it`s habitat as surviving is the hardest for the apex predator of that environment, you don`t want to be part of that environment this animal once lived. It should be a such tough place if Rex was evolved like that just to survive
Back in 2021 a study estimated Sue´s bitefoce as 9.6 tons
And Keep in mind that Sue size is 12.40 meters long and weights 9.3 tons
@@GanteSpruce Thanks for information
@tossupeaterDo you know who did that estament? It seems somewhat reasonable considering Dan Folkes estamated Scotty to be 10.55 tons, but I want to look into it.
@@AgroAcro I doubt is from a legit source.
Dan last work put Scotty weight in 10.45 and the length in 12.35 meters
Meanwhile Sue weight is 9.8 and the length is 12.37 according to Dan
An outdated study from 2011:
"This study found that Sue could be around 9502 kg that is 10.4 tons. These results were achieved by giving Sue a 13% broader model"
But another study from 2014:
"This older study concluded that Sue was around 7377 kg (8.1 tons) while Scotty was 8004 kg (8.8 tons). Scotty was estimated to be around 8 percent larger than Sue"
Then another study from 2018:
"That got results similar with Sue being 9130 kg that is 10 tons and there was also a higher result that placed Sue at 9713 kg so 10.7 tons"
"There are issues with these higher end estimates. Because the models being used have areas with questionable tissue added and this can effect how accurate the results are"
"The tail is bulked up and the flesh added is excessive and this will effect the results of the study. So far our current understanding of Tyrannosaurus does not support this look for the animal"
"There is nothing to really suggest it carried this amount of flesh on its tail so this means it is probably a good idea to not use this model for Tyrannosaurus rex unless you want to get really high mass estimates"
Before Dan´s recent work though the very last study put Scotty weight at an estimated 8870 kg (9.7 tons) while Sue was estimated at 8462 kg (9.3 tons).
Scotty was around 400 kg to possibly 500 kg heavier than Sue.
Then Dan shared his work about density and GDI analysis and now Scotty is 10.4 tons and Sue 9.8 tons
Also, Henrique Paes aka RandomDinos has updated his work on Sue.
The estimated length is 12.40 meters, the height is 3.90 meters and the mass is 10 tons
Pretty similar to Dan´s own work: 12.37 meters long, 3.7 meters tall and 9.8 tons
@@GanteSpruce Dan Folkes website currently says Scotty is 10.55 tons, that's where I got my number from. Like you said the thing that seems a bit off about the 10.4 tons Scotty and 10.2 ton Sue is how close they are. Scotty definitely seems more than .2 tons heavier
At this point the Tyrannosaurs are like the Saiyan race in dragon ball. There only rivals are each other.

The chonky beast! I'm surprised at how quickly things have changed with T.rex's mass estimates since our Megatheropod videos came out. And Bertha might shake things up even further!
This kiddo here too
@@TheVividen i see what you did there... Bertha shaking things up. 😁
After looking through the comments section, I found that there are still some misconceptions. I will explain each of them here
1.Cope's fossils are not fragments, please stop calling a complete femur fragments. The femur is more reliable for estimating body size than a bunch of pieces put together, and it's the most reliable bone for estimating body size. Except for Spinosaurus and a few individuals. In theropod dinosaurs, femur circumference is directly proportional to body weight. The 10% completeness was before the discovery of Cope's femur and tibia. A complete femur and tibia would be significant for any theropod dinosaur.
2.Cope's legs are not short, there are many different standards for measuring the length of the femur, measuring it at different positions may result in different measurement results. we don't know exactly where Paul measured the length of the femur. Taking Sue as an example, there are many different versions of Sue's femur length, as Sue's femur has been measured by many different paleontologists. 132cm is measured to the greater trochanter of the femur, Larson's 134cm is measured to the lesser tubercle of the femur, and the measurement to the femoral head is approximately 140cm. But the measurement of femoral circumference is relatively uniform, for example, Sue's femoral circumference has always been relatively uniform at 580mm.Referring to the Trix measured by Paul, the 117cm femur length has a circumference of 530mm. Perhaps his measurement method may lead to a shorter length. The 117cm femur length has a circumference of 530mm. Perhaps his measurement method may lead to a shorter length.
In addition, leg length depends not only on the length of the femur, but also the length of the tibia, the height of the iliac crest, and the metatarsal bone. Cope has an intact tibia. In the image, the tibia and femur are placed side by side, and judging from the image, the tibia of Cope is definitely long, at least no shorter than 120cm. This also makes her tibia longer than sue (120cm)
3.DAN's weight estimation is very accurate, and his drawings are of high quality. But you'll notice that his estimates of giga's body size are significantly higher than others. This is mainly because the spine of the vertebrae in his GIGA's back is drawn higher than others, and there is an extra volume here. But I must make it clear that the fossilized vertebrae of giga have never been described and measured in any one paper, so we don't actually know the exact size of these vertebrae. I don't know what information he got to draw giga's nerve spines so high. You can take Dan's weight estimate as a reasonable guess, but please don't take it as the latest research or as an established fact. Just because it's the latest doesn't mean it's necessarily the most accurate, nor does it mean someone else's smaller weight estimate is wrong or out of date.
4. One important factor that we often overlook when comparing body types is age. Dinosaurs didn't just stop growing when they reached adulthood. The emergence of EFS means that the individual has almost no room to grow. I often see people say it's unfair to compare CH1 to sue or scotty. However, this is actually quite fair, because CH1 itself is an asymptotic individual just like SUE and scotty, an individual with EFS and no room to grow. I included in my post the osteological evidence for why CH1 is an elderly adult, as described by Coria, the discoverer of GIGA. Yet I have never seen anyone in the paleo media address this important issue. Even many people think that CH1 must be a relatively small individual, when in fact it is more likely to be a relatively large individual in the giga population. I've listed all the Tyrannosaurus rex specimens that we know for sure have no room to grow, and out of seven specimens, 5 of these 7 specimens are larger than CH1, and 4 of these 5 are significantly larger than CH1. One is about the same size as CH1, not too far apart, and one is definitely smaller than CH1.
BODY SIZE NOT BODY TYPE
There's one more thing I want to mention，There's a good chance that Cope is ”Manospordylus gigas“. That huge vertebrae,Its serial number is AMNH 3982, formerly known as "Manospordylus gigas", but later confirmed to be Tyrannosaurus Rex. Because it seems to have been discovered in the same place as Cope, and Larson briefly described (Cope)BHI6248, a portion of stacked vertebrae were discovered at the location where Cope was discovered. It seems that someone intentionally stacked these bones a long time ago, suggesting that this place may be where Cope himself collected two vertebrae from the skeleton of "M.giga" back then. It is said to be 10% larger than the same part of sue.We know that vertebrae size is also highly correlated with size.If this is true, as Larson suspects, then this is yet another strong piece of evidence that Cope is likely to be considerably larger than Sue
If Cope is indeed M. Giga, it would mean that Cope was actually the first Tyrannosaurus rex discovered. The first and the biggest. What a legendary animal
I don't know why I can't post a link, but if you want to see the details and explanation of # 4, you can search the title on the dinosaurs section of redit
“Is the holotype of Giganotosaurus really larger than most Tyrannosaurus Rex specimens, as many people claim?”

Anyone who undoubtedly beleives the 10.4 tonne Giganotosaurus paratype estimate should undoubtedly beleive this.
Better yet: People truly believe Spino´s single snout bone fragment reach 14 meters long and weights 7 tons. The paleo community seems to accepts this as a fact.
Then they should too accept this fragmentary remains and the estimates too right?

T-rex is heavier than Giganotosaurus again, but Giganotosaurus is taller and longer!

T-rexes are like the Salt Water and Nile crocodiles, when you think you have found the biggest specimen, a Gustave or a Cope appeares. And this just T-rex alone, we don't know if other giant theropods like the Gigas, Carchars or Allos could had reached humongous sizes.
So... a Jurassic Park type of T-rex could had been possible.
There’s also a newer specimen nicknamed Bertha, there hasn’t been a study done yet but the paleontologists who are working on it noted the femur was larger than Scotty’s.
could it be possible that Bertha might be 50 feet or more in length?
Big Bertha, c’mon with these names 😂
@@alanwilcox98 Right now there isn’t any information on this specimen, just that the femur circumference is thicker than Scotty’s. Which is often means it weighs more.

A truly massive biped. Getting to be that size means its prey was large as well: hadrosaurs, ceratopsians, and defiantly sauropods.
welll considering the only sauropod it lived with was the absolutely titanic alamosaurus im not sure about that last part
Likely not sauropods because there weren't any in Hell Creek where Copium was dicovered.
@@gladiolus5377 we don't know the extent of their ranges. Large Sauropods don't tend to fossilize well. That said, T.Rex wouldn't have hunted the absolutely colossal adults, even if their ranges did overlap.
large sauropods wouldve been out of the T-Rex's menu for sure. theyre not built for such a task unlike say the Carcharodontosaurids like Giganotosaurus and Mapusaurus, young sauropods wouldve been fair game but after a certain size range an adult Alamosaurus wouldve been invulnerable to even T-Rexes like Cope and Scotty
I doubt it killed sauropods, i can’t think of any predator that could kill a fully grown sauropod.
The t-rex is almost guaranteed to grow significent larger than the biggest speciments we have uncovered today.
Smaller individuals was more likely to die earlier during cometition from stronger individuals. This could be everything from starvation due to bad access on good hunting grounds, death by territorial behavior, falling prey and a harder time cathing prey. Unexperieced animals are also more exposed for earlier death. These animals more than often die due to lack of enviromental knowledge and making bad decisions which again results in dangerous and deadly situations- getting stuck, drowning, falling down cracks and cliffs, killed during hunting, becoming prey, etc. Some of these types of death, under right circumstanses, gives the dead body better conditions for preservation. Bodies buried in mass without oxygen and organic matter gives good conditions for preservation.
The bigger and more experienced animals has a higher chance to die in areas where their bodies usually dont have the right conditions for leaving behind evidence of the animals existence. For t-rex this would likely be in places with much water and a high micro layer of soil suporting big prey and other predators. These conditions would make short process of any carcass, even the bones.
We see these circumstances with animals today, so this rule can certainly be applied to the dinosaurs, especially the spieces with better cognitive abilities like the t-rex.
Animals with small brains and low intelligence makes decisions mostly based on instincts, not by thinking, which basicly remains the same throughout their whole life and therefor more likely to die under simular circumstanses.
This behavior, some times, results in less difference when it comes to the individuals age in fossils and carcasses.
The t-rex is belived to have a intelligence comperable to primates, elephants, crows and dolphins which makes it a thinker and learner. This means their behavior changes troughout their life, making the animal less likely to die by error and poor judgement each surviving day. The biggest specimens had "fulfilled" their learning curve, making it a very smart and experieced predator, more likely to die by natural causes and therefor had worse conditions for preservations.
Throughout t-rex's time on earth- 2.5 million years and 125.000 generations, scientist believe that there had been 2.5 billion individuals, which some over 40 have been found. Some of these individuals are estimated to be around 8-10 tons. My point is that these individuals do not represent the spieces maximum size and the t-rex could most likely get much bigger.
African bull elephant normally weigh in around 5 tons, but individuals with a weight of 10 tons are recorded. Thats twice as big. These behemots dont represent their spieces normal traits, but they do represent, with the right genes and circumstanses, the estimated maximum size.
I'm so glad people are finally understanding this.
Based on a normal distribution alone 10 ton trexs were likely the norm.
With exceptional individuals possibly reaching 50 feet in length and around 16 tonnes in mass.
It makes you wonder how many creatures will never get to know about because they were either too rare grew up in a tropical environment where fossilzation is unlikely or straight up chased out of any ecological niche by literal monsters.
The thing is, this applies to literally every living thing in the entire planet’s history. So it’s not really worth bringing up.
Giga fans thinking they had the lead
Rex comes back even bigger every time 🤣
A predator weighing 2 African elephants is bonkers
On a side note though, if a giganotosaurus specimen is found even bigger than the current ones. They should name it “Gustav the giga”
If T.rex got that big and lived in groups, I'm still going to consider that Albertasaurus "family" as support for that possibility, then full grown Alamosaurus would've been the only thing in the ecosystem that could potentially consider itself safe.
Yeah, I doubt even a group of T.rex would go after an adult Alamosaurus. Anything else would have to really watch their back.
Scotty doesn’t know. Don't tell Scotty.
It's called Cope Rex because Giga and Spino fans must be coping and seething right now 😎
at least Giga and Spino are actually predators not scavenger.
Copium Rex's thigh is shorter than Scotty meaning Copium Rex is only 9.5 tons . 12.4 tons isn't official.
Scotty is the biggest T rex that weights only 10.4 tons
With the current official estimates Giganotosaurus carolinii is still the biggest carnivorous dinosaur that weights 10.6 tonnes
@@boi9842 lmao do people actually believe that???!!! What is this??? 2003???
@@boi9842Aaaand there's the copium lol. There is actual evidence of Rex attacking live prey (though it would no doubt take a free meal like most predators would), so it's clearly not an exclusive scavenger.

@@David-ni5hjall serious scientists agreed with that until T rex fans sent death threats, so they had to accommodate science to pop culture pressure because T rex fans are obnoxious.
I was about to lay some calcs down when you tackled that, its interesting how we all know there is longer theropods but none that are heavier or more advanced then T rex.
This is a great video Viv. I definitely think that limited sample sizes have led to misunderstandings of the upper-limits of Theropods. It works the other way as well. _Nanuqsaurus hoglundi_ was claimed to be a pint-sized Tyrannosaurid on the basis of incredibly scrappy fossil evidence and the theory being based largely on it's place - and latitude - of discovery. The idea of resource scarcity inspired the notion of it _reportedly_ being a 6 metre long animal. The likes of Gorgosaurus and Albertosaurus, in part, lived under the Aurora Borealis as well, though they did not exhibit dwarfism.
Coming from the Prince Creek Formation, in Alaska, in the High Arctic, it did make some sense though the evidence was far too sparse to be too sure on a 6-7 metre maximum adult size. The larger estimates are now hovering around 9-10 metres for the big adult _Nanuqsaurus hoglundi_ which to my mind, seems more reasonable, after taking a glance at Daspletosaurus, Gorgosaurus and Albertosaurus. It wasn't a bad idea it's just that the evidence was far too limited to justify it, and so it begs the question, couldn't the same be said on the other end of the scale?
I often remind myself not to put too much stock in given upper size estimates for _any_ Dinosaur, because the chances are, there'd be a somewhat dubious margin of say 10-20% (I tend to stick to 10% as a generic rule of thumb), where giant individuals will exist. Obviously it would be great to be able to (safely, omnipotently, floating around in Minecraft Creative Mode style etc) see the Dinosaurs in their habitats and make Zoological studies (rather than Palaeozoological ones from the fractured hindsight of over 66 million years)
All the same, we have to deal with the taphonomic biases which beset most palaeontological study in general, regarding the sample sizes, preservational quality, factors in each palaeoenvironment creating preservational biases and then that little old problem known as geomorphological processes. Everything from plate tectonics and subduction of crustal strata (as happened to what had been the vast majority of the seabed of the ancient superocean of the Panthalassa/Panthalassic) to the typical geological faulting, folding and erosion processes that go on for hundreds of millions of years, can ruin the day of any fossil trying to make it to being found at all.
The old tropes of how fortunate it is to find any vertebrate fossils, begin to become exponentially unlikely and fortuitous, with the complexity of the preservation observed, the quality of the preservation and the potential animal behaviours, even possible to be demonstrated. All told, the odds of finding something like say, the Sue Specimen, are rightly considered astronomical. Most Dinosaur remains won't come close to 90% complete (or about ~93% complete in the case of Sue, from the top of my head IIRC)
Most Dinosaur skeletal remains in body fossils, won't get past 30% complete. Fossils begin as being lucky to be fossilised in the first place, then have millions of years of time to risk being destroyed or lost to time anyway. Right this moment, there are almost certainly fossils falling into rivers, into the oceans, to be destroyed hydrologically and eroded physically and chemically. There are almost certainly going to be more lost (by far) than are ever found.
And that is before we consider the human impacts on fossils like quarries often just destroying them unwittingly (yes fossils can be saved, but it's obvious the primary concern of a quarry is it's business related operations, and I have no doubt some exquisite fossils will have been utterly annihilated over the decades. It is sickening but there you go. Imagine surviving as a fossil, relatively intact, for 100,000,000 years, and then being dynamited in some quarry and then ground to powder or grit for buildings or components of something else? It's really tragic.
An inestimable treasure, lost forever, by industrial processes for no reason other than indifference. Then there are other ways this happens, like Dinosaur fossils having been ground down to powder for 'traditional medicine' and 'supplements' in China for about 5,000-6,000 or so years. Dinosaurs, being considered Dragons. Dragons, thought to be divine, and ancestral to the Emperors themselves. They represented power, virility and prosperity. Naturally, humans managed to make Dinosaur bones into alleged, ancient aphrodisiacs, while calling them Dragons.
It apparently still goes on, though I couldn't speak to that if it did or did not currently. I just know for sure it _did_ go on for literally thousands of years, and it makes one wonder how many unique specimens were completely destroyed, consumed and not to put to fine a point on it, shat out. It's just depressing. Then we have other ways a fossil can meet an untimely end because of humanity, like a war causing a museum to be obliterated by bomber raids (as happened in WWII; see Hamburg Museum) and also vandalism (see Canada in 2012 ish when a beautiful specimen of a Hadrosaur was slegdehammered to pieces over-Winter, breaking the hearts of the team of palaeontologists whom left it under a tarpaulin to protect it under from the elements while they waited for Winter to end; the specimen, destroyed by drunken youths being disgusting)
The odds are stacked against high quality vertebrate fossils being found at all, in general. They don't need humanity's help to get destroyed. Nature destroys more than we ever could. It's just extra depressing if humans do it on purpose or by accident. Like the Allied bombing raids on Hamburg obviously weren't specifically aimed at taking out the museum in WWII. It just fell foul of carpet bombing/area bombing in WWII. And that was that. Inestimable treasures from prehistoric times, turned to shattered, crumbling fragments and dust. Yes these are rarer examples (thankfully) though it illustrates the madness of a process of chance and fortune, that a lot of fossils have to unwittingly go through to get to palaeontological collections. It's not just unlikely they'll become a fossil in the first place. That's just where the process begins in earnest. I won't whip out the 'lottery win' trope to describe it though.
By implication, it always seems unwise to me for folks to stridently argue the toss about literal ten centimetre scales of difference between their favourite Theropod mascots and pin-ups so to speak. Human ego plays into things too often, with people fighting over it when really, it doesn't even need to be one. Ironically that can generate more work and keener focus on getting one argument across, and if anything, 'drama' in the palaeo world can be helpful in indirect ways.
Even so, I prefer a cooperative and constructive environment when looking at these things. I can't remember the last time I argued with anyone over the size of this or that Theropod, because I specifically avoided/avoid that kind of shouting match. i just want to try and be as up-to-date with the state of play in palaeontology, and keep refining what I think I already know about the subject, like everyone else doubtlessly is trying to do as well. Not one palaeontologist in the world can have anything like all the answers, and this is why the group effort in my view is invaluable and vital to making a difference.

I've got to agree with you there. I mean, with the error range of allometry + accounting for volumetrics being more accurate the absolute top max weight for Cope is just shy of 15 tonnes. I think the 12-tonne range is more accurate, but it goes to show we're getting closer and closer to the theoretical max size!

Scaled from Sue and got 13.12m length for Scotty. May be a better estimate as most estimates before Dan Folkes gave 13m
Nice Copium Rex 🔥
Something worth noting, the listed figures show that while ED Cope has a wider femur than Scotty, its actually slightly shorter, so ED Cope was probably a slightly shorter animal in terms of overall length (the correlation between femur and overall body length is pretty strong), and consequently may not have outweighed Scotty by as much as estimated because length effects overall mass too (square cube law). Another interesting thing I see is that according to this chart Stan has the longest femur of all the specimens at 1350 mm, this suggests that Stan might actually be the longest T.rex (though given that it was a relatively skinny specimen it certainly wasn't the heaviest), the latest estimates for Stan that I've seen give it a length of 11.78 Meters, but this is based on a femur length of 1280 mm, if Stans femur is truly 1350 mm than the former is definitely an underestimation of overall length. Anyone know why is there such a discrepancy with this specimen? Has Stan received a proper description?
Tyrannosaurus had proportionally longer legs when younger, so maybe it had something to do with that?
True, but the overall length would still be higher in adults, so if Stan has a 135 cm femur, then it has the longest legs overall, and would have one of the longest bodies (if not the longest). Some of the figures in the chart make me a bit skeptical though, according to this chart Trix is one of the smaller adult specimens even though all media described it as near Sue sized. It also includes measurements for Samson which is not a specimen thats accessible to verify these measurements. @@dino_drawings
The correlation between femur length and total length has been overestimated. especially given the wide disparity in the ratio of leg length between different types of theropod dinosaurs, and even in Tyrannosaurus Rex, the relationship between femur length and body length is often skewed. And the standard for measuring femur length in this table may not be consistent. It did not specify the measurement criteria separately. Stan's femur is also not the longest, 135cm is the largest version of all measurements, sue has had a larger version than 135cm.there are many different standards for measuring the length of the femur, measuring it at different positions may result in different measurement results. we don't know exactly where Paul measured the length of the femur. Taking Sue as an example, there are many different versions of Sue's femur length, as Sue's femur has been measured by many different paleontologists. 132cm is measured to the greater trochanter of the femur, Larson's 134cm is measured to the lesser tubercle of the femur, and the measurement to the femoral head is approximately 140cm. But the measurement of femoral circumference is relatively uniform, for example, Sue's femoral circumference has always been relatively uniform at 580mm.Referring to the Trix measured by Paul, the 117cm femur length has a circumference of 530mm.The total length of Trix is likely to be larger than Stan. Perhaps his measurement method may lead to a shorter length. Or Trix is an individual with a relatively short femur.
Cope also has an intact tibia. In the image, the tibia and femur are placed side by side, and judging from the image, the tibia of Cope is definitely long, at least no shorter than 120cm. This also makes her tibia longer than sue (120cm)
Well then with all due respect to whomever put that chart together, its not very useful data unless all the specimens were measured consistently between each other. Otherwise its very confusing. @@Super-Masterpiece34

The specimen bertha has a femur thicker than scotty, though this is not enough to confirm its larger, there are other, smaller rexes with thick femurs aswell. The holotype femur is thicker than stan's, but stan is the larger animal
I think the difference with this one is the amount of extra thickness is just too much, even wit smaller estimation would exceed both sue and scotty. 580,590 vs 630, 630!!

Also I was curious if you knew about the Portland Formation Neo Theropod that was described in September of 2021, that only half of the hip of the fossil was discovered. Using the hip they incurred that it was similar to Dilophosaurus and Cryolophosaurus, but it’s hip’s bone was thicker than both of them and it was larger than them, with the specimen potentially 9.1 meters long. Additionally there are footprints in the surrounding formations and the Portland formation that are estimated to reach up to 8.5 - 9 meters long. I just found it neat that there is such a large dinosaur just walking around the East Coast just 1 million years after the Triassic - Jurassic Mass Extinction.
T Rex is a scavenger not hunter. Don't know how to kill prey.
@@spinosaurussp My dude, 2001 called, they want their wrong studies back
@@spinosaurussp Allosaurus, Torvosaurus, and Saurophaganax were just scavengers. The only thing hunting stuff in the Morrison was Ceratosaurus and Marshosaurus. Ceratosaurus is the primary carnivore of stegosaurs and diplodocus.

@@beedrillbot121and allosaurus only preyed on fish!
@@spinosaurussp😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂”scavenger” in your ass…
I've actually visited the Black Hills Institute early this year. They are a pretty good place.
Jealous
I'm jealous. I've never seen a T.rex fossil in person. I went to Chicago on a school trip but unfortunately we didn't see Sue, we went to another museum that only had stupid things like rockets.
@@AgroAcro You poor thing. No seriously, that's sad.
@@AgroAcro I saw Stan earlier this year, and damn, you just don't realize how big T.rex was before you see a skeleton, it was extremely impressive.
@@Doomguyhunter1 Stan is also a relatively small T.rex, so others would be even bigger.
I hope we can find a complete 14 meters long and 4 meters tall T Rex fossil
Y’know what would be funny? If Cope Rex found a home at the Yale Peabody Museum which the place where his namesakes rival, Othniel Charles Marsh was a professor at.
Awesome! A new T-Rex Specimen, bigger than Sue and Scotty!
Probably smaller since it's fragmentary
@@spinosaurusspBut you don't say that about Giganotosaurus.
@@Tyrannosaurus_rex. You mean Spinosaurus...
It´s funny how fragmentary bones only seem to count for Spino.
I mean, MSNM is just a snout fragment and nothing more and yet this specimen is always THE Spinosaurus
FSAC-KK should be THE Spinosaurus since is the most completed fossil.
But the thing is MSNM is 14 meters long and 7 tons (a freaking single bone fragment)
Meanwhile FSAC-KK is 11 meters long and 3 tons... Tail, legs, neural spines, ribs and some vertebrates...
@@GanteSpruce the smaller specimen shows signs of not being fully mature. That’s why.
@@spinosaurussp A whole femur and a bunch of other smaller bones isn't precisely fragmentary. Especially when the femur is the most important bone to estimate body mass, and its circumference is much more important than its lenght.
W Video, common Tyrannosaurus rex W (but the comment section hurts my eyes)
fr😭😭😭
Same
Cool but really want to know tall at the head and better length estimate when can however thank you very much for the update.
There were also 2 humerus bones that were bigger than Sue´s humerus 39 cm.
The bones were for sell for what I remember. Does anyone know what happened with them?
They really told Scotty to cope
