How Fast Was Tyrannosaurus rex? Tyrannosaurus Speed Explained

- How fast was Tyrannosaurus? Dinosaur speed is a complex biomechanical question, and paleontology is always advancing. Could a human outrun a Tyrannosaurus? We all know the iconic scene in Jurassic Park when Rexy is in hot pursuit of the Jeep, but how realistic is it? Could a ten-tonne bipedal predator really run at the 32 miles per hour that John Hammond claimed, or was that movie magic? If not, how fast was Tyrannosaurus rex? Tyrannosaurus is the most well-studied dinosaur out there, with dozens of specimens in various stages of completeness and over a century of research to its name. Part of its fame is due to its killing adaptations and impressive size, but it’s also just known from a huge sample size compared to other large theropods and is therefore much more practical to study. Much of the information we’ll be discussing is likely applicable to theropods in its overall weight class, like some of the big carcharodontosaurids, although tyrannosaurs did have some unique adaptations. Snively et al 2019 found that tyrannosaurs were pound for pound twice as agile as allosauroids, for example, thanks to higher proportional muscle mass. Tyrannosaurs, along with ornithomimids and other ostrich-morph theropods, also had a special adaptation for running called the “arctometatarsalian condition.” This means that their middle metatarsal, essentially the toe bone, is squished between the others. It increases shock absorption when running and indicates a capacity for greater speed over long periods of time.

So the top speed for a juvenile T. rex was 14 to 32 mph based on this new publication, while an adult could reach 17 to 23 mph based on size? That's both scary and incredible!
A Megatheropod bigger than an elephant running at almost 30 km/h is truly a awe-inspiring and nightmarish sight to behold.
And yet you still would say that being hunted by Tyrannosaurus is worse than by anything else (even tho Tyrannosaurus is slowest megatheropod)
@@roguetheoutlander8800 In terms of megatheropods, Saurophaganax was probably the slowest actually given its severely underdeveloped fourth trochanter
Imagine how many flags we would put t rex on if we knew it existed in earlier time periods
@@roguetheoutlander8800It would be terrifying, I mean who’s not shitting their pants when they see a 12 ton Superpredator running at them at the speed of a house cat?
Now imagine a Juvenile tyrannosaurus hunting you, that’s the scariest scenario I could imagine.
Giga can run 50km/h
I think the opening scene from Disney's Dinosaur with the Carnotaurus ambushing, then running down a panicked Packyrhinosaurus is how I'd imagine a T. rex's hunting would look like (considering it was designed originally around a T. rex). A mix of ambush and short pursuit. Not a mammalian endurance runner though, something in between.
That scene is still incredible.
Trex was a glorified vulture
@boi9842 we have evidence of failed hunts so it did attack stuff, its likely it did eat whatever it could find but that goes for every predator ever
@@boi9842😂😂😂😂
Do remember though, mammal endurance and archosaur endurance are not the same.
Also take into account that Theropods are bipedal, they had much more energy efficient locomotion style than quadrupeds.
Think of Theropods more akin to ancient homosapien hunters.
Run, run as far as you can, while you still can.
You don’t have to outrun it. You just have to outrun your friends.

What's the top speed of a 1993 Jeep Wrangler, carrying three adult humans, that's stuck in second gear (because a wounded man is laying on the stick shift)?
That's a good question actually lol
i have a slightly older jeep wrangler, and mine at least gets to around ≈20-30 before you need to shift again. maybe around 25? i dunno, i havent paid that much attention to it before
First off, it was either a 91 or 92 based on purchase histories. Second, based off my YJ, 0 because second is stripped out
@@quentinking4351 "Get off the stick! Bloody MOVE!"
I love imagining all the behavioral possibilities for Rex especially given how drastically their physical capabilities change throughout their lives. In such competitive ecosystems it was probably only the most fit and intelligent Rex that would make it to full adulthood.
Yes but yo mama 😮
Nocturnally: T-Rexes have eyes the size of tennis balls, huge nasal cavities, and limited ability to conceal themselves (due to their sheer size). I think the adults were nocturnal ambush predators using their phenomenal night vision and sense of smell, while the younger ones ran.
I have a pet theory that endurance running was a form of mating display, the males had to keep pace with a female before being chosen (but that’s pure imagination).
I like the speculation!
You know I think about this as well.
Possibly the other way around. Maybe the smaller males have to walk on egg shells mantis style as to not get killed/eaten by a moody female (kinda like a mantis.) Outrunning the bigger aggressive females giving them an opportunity to mate with them after exhausting them.
Source- I made it up.
My mating display theory is that the male Rex brings the female a gift: the largest body part of another dinosaur it can carry. 😂
@@jessehutchingsby that do you mean Caseoh?
Really neat to hear about the latest research! And it's satisfying to see the new paper has T-Rex being pretty fast. I've still aggravated by the 1990's Horner-inspired image of T-Rex being a slow and dim-witted scavenger.
We're still recovering from the collective trauma of Horner's takes on rex

T.Rex must have been a sight to behold. A 10 ton carnivore as long as a bus, moving faster than most people can run and making deep rumbling calls making your chest vibrate
You can’t outrun it, you can’t out endure it, you can’t outfight it. And just when you think you’ve escaped, it’s already outsmarted you

You can aout walk it. It has been proven it was slow.
@@Leon-bc8hm "slow" probably not
T Rex on top baby
A T-Rex as large as Stan could (possibly) enter a true run? That's quite frightening. I'm curious to what this could mean for the other megatherapods.
It couldn't
Stan was probably too large
@@Leon-bc8hm 🤣🤣
Considering the energy it takes to run and the risk of it not catching its prey, could exhaust it (as it does modern pursuit predators) I think it would have to be a short burst runner, but not a pro-longed pursuer. Fast in bursts, but if gaps between it and the prey were already close enough to charge at it. Kind of like how the Jurassic Park Jeep scene is (where the T. rex likely walked up to a few feet from where the Jeep was, burst out of the trees, then did a short pursuit but gave up after a few minutes due to it already knowing it wasn't successful). Ambushing at low-light, dawn, twilight or at night would give it the most opportune chances I think. I think something not talked about, would be its stamina to judge how fast and how long it could run for, as a predator.
I love the new nocturnal ambush predator idea. They could also be endurance pursuit predators like us or wolves too. Look at the shuffle jog of elephants - rexes didnt need and weren't able to go faster than that.
T rex was a long distance runner
I've been saying for years that t.rex was most likely a persistence hunter. It was too big and conspicuous to ambush and too slow to chase things down in a quick sprint. It's entire body is built for endurance and power. It's senses are tuned for tracking over long distance. It wanted its prey to run. It wanted to methodically chase its prey to the point of exhaustion so that the prey could not fight back. And since the prey could not fight back, it didn't matter if the prey animal was a grown adult or not. In fact, when it comes to something like a triceratops, the bigger the animal and the bigger the horns, the more quickly it would become exhausted.
So I imagine the t.rex was very intimidating and not very stealthy at all. It would plod into view of its prey, making a lot of noise and probably baring its teeth, trying to frighten the prey animal into running. Then when the prey animal sprints away, the t.rex follows at a slower, but still brisk pace. The prey animal gains a lead then stops to rest, but before it can regain much stamina, the t.rex catches up, so the prey animal sprints off again. Repeat this several times and the prey animal is on wobbly legs, overheated, gasping for breath, unable to run or fight. The t.rex catches up a final time and delivers a killing bite, or just knocks it over and starts eating it alive. Either works.
Definitely appreciate this video . Mike
Don't forget Cenozoic theropods for Australia and South America, try to do it soon
They're on the docket, along with the Asian episode!
Mesembriornis would be cool. Imagine a terror bird about as fast as the modern pronghorns.
Wow these figures turned out way better than I thought they would! The king is back!
What about cope? Could the unusually long tíbia make him faster than other rexes? If so, by how much?
It's definitely a possibility! Until the scans get published it's hard to specifically estimate, however
I couldn't find the exact measurements on the leg of Cope so had to approximate, but if you run it through the formulas (and Froude Number 1 for conventional walking) you get between 5.8 to 9.1 m/s. Given that Cope is probably heftier than any of the sampled specimens and likely does not have a COM within the needed range, running is improbable. Of the recovered range it's hard to get a good assessment since no data is available on musculature. If I had to put in a ballpark estimate, I would guess it's slower than FMNH PR 2081 just due to the limitations on force generation in movement vs body mass, but still reasonably quick for such a massive animal.
@@TyrannosaurusRex5027 I know that the femur is 127 cm long, 63 cm in circunference. As for the tibia and fibula , the measurements for length are 123 cm and 108 cm, respectively. I’ll take a look at the math.
Gotcha. Used the femur and tibia/fibula with the foot and cartilage being proportional to FMNH PR 2081. Same formulas (excluding running again) for a range of 5.6 to 9 m/s. Similar conclusions to above, we will need data on musculature to help narrow the range and make a more sound conclusion. I wouldn't be surprised if cope was faster than other T. rex of its size, but still is probably slower than any of the sampled organisms.
@@rayquaza166 the femur is likely longer than 130cm since the original measurement was wrong, apparently - idk much more though, just try like sue’s femur length
I quite like the take that giant theropods were basically persistence hunters like early humans: they can’t effectively hide in the bush and they can’t chase prey in a run, but they have extremely efficient respiratory systems like a bird and they have very efficient walking gaits, allowing a megatheropod to essentially “jog” prey to death before closing in with more than enough bulk and cutlery to dispatch an exhausted prey item.
I’d imagine a tyrannosaurus having a combination of ambush and pursuit for like edmontosaurus’ but for the more heavily armored herbivores like triceratops to be much more on the ambush side
Now I’m really looking forward to the upcoming study.
Love your Rex vids btw, any news on the Bertha specimen?
Glad to hear this new study ive always hated the idea of rex not being able to run when its main prey items like hadrosaurs could've probably outran it easily if it could only power walk at them.
I guess my inconsistent sleep schedule caused me to miss the premiere lol.
So running away from a Rex wont work for me. Welp, guess I'll hide!
Hopefully humans are small enough that the adults wouldn't be interested. The juveniles, on the other hand...
Pray and hide will be the strat here. Or climb to a place where the juveniles wont reach me.
I’m building a time machine asap
I imagine rex like a bear, when they do hunt (rarely) they always try to close the distance so that they get their food quickly, but if their prey (like horses, elk, deer, etc) notice them and start running then they can switch to endurance mode, and some bears have been recorded running for a long time. So a rex with a good ambush could take out quicker or stronger prey, but even if that didn't work it could still chase it down.
i don’t think Tyrannosaurus hunted rarely, scavenging wouldn’t have made up enough to keep it going - I imagine it personally as an ambush predator that could chase down prey if necessary; being the largest and strongest animal in its environment also helps it since it could probably take the herbivores in Hell Creek and other places head on (though it would definitely not prefer to take a Trike horn up its chest, lol)
@@Chadhadiya-yc2ct I was talking about bears, not tyrannosaurus, tyrannosaurus would 100% hunt very often since it would need a lot of calories and wasn't able to chew plants very well.
@@rylandfrederick431 my bad, misunderstood your comment
@@Chadhadiya-yc2ct nah no problem I kinda worded it weird
@@rylandfrederick431 allg
T. rex 🤝 humans: killing faster prey by stamina.
Now, it is interesting that Tyrannosaurus has a much wider chest in comparison to Carcharodontosaurids, which means it could bear bigger lungs and thus have a higher physical capacity, either speed or stamina.
Lmao people still believe that endurance hunting garbage about humans?
@@cheeks7050 Please, enlighten us as to what the truth is about early human hunting.
@@JurassicClark96 Obviously there's many different strategies like trapping or ambush hunting, or whatever it's called when you run an animal off a ledge so it falls to its death, and they were all used.
To come to the point, persistence hunting is literally the most calorically demanding form of hunting possible. It's a terrible hunting strategy that starves you if the hunt fails.
Humans are also not actually better at endurance than most other animals, rather endurance hunting is made possible because humans can carry food and water with them in containers. The only tribe left on earth that does this hunting method walks (they do not run), and they live in a very hot climate, and they carry supplies with them, and they operate in a group.
There is also basically no evidence for persistence hunting in our past. People only like the idea of persistence hunting because it would be cool if humans had a special ability like other animals do. But our special ability is our intelligence, and it's pretty dumb to run something down when you can trap or ambush it instead.
@@cheeks7050that’s literally how humans hunted prey
@@cheeks7050 The question of whether humans are, or are not, the best endurance runner in nature is determined by largely by the environment, humans universally preform better than any animal I can find over very long distance in a run in hot weather environments, other environments can reduce or negate our natural cooling advantage from our lack of fur and our above average ability to sweat (horses sweat to a similar extent but are obviously covered in fur, this reduces their ability to lose heat). I will agree that it's true that humans probably didn't evolve to specifically tire out prey, but endurance is likely a part of our success.
Also humans do in fact have 'special abilities' extraneous to intelligence like our incredible dexterity, the aforementioned ability to travel long distances without expending much energy, and our, largely neglected by most, eyesight, particularly our ability to focus on fine details that makes reading and fine tool making possible and viable, for example cats have great eyesight for detecting movement but struggle at close up objects and fine details therefore even if a cat was intelligent enough to be taught to read it would struggle to do so in most common reading applications (like reading a novel, or reading the fine print on a newspaper).
This belief in humans being weak is senseless and is rooted in the personal perceptions of people who have not lived the hard lifestyles of their ancestors, which is certainly not a bad thing as those lives where often hard and full of strife.
If Cope had longer legs bones than Sue as you previously covered, could he be faster despite being heavier?
Potentially! Once the scans of the bones are published we'll have a much better idea
@@TheVividen Interesting stuff
I've heard though rex might be getting even bigger, wonder how that'll all balance out.
It makes me raise the question, what would this mean for Hadrosaurid running speeds
Potentially faster than thought!
It’s all good looking at the animal itself but ecology is a big factor. You only have to outrun your prey. And if you’re an ambush predator only temporarily.
Yep! What's interesting is how looking at the animal itself also indicates potential ecological roles, and makes us wonder what we might be missing about its prey items. What don't we know?
@@TheVividen yeah there’s so much we still need to know. It why I chose palaeontology over astrophysics. Because I think I could give more to the world in this field that despite its age, has only just begun.

This video is pretty helpful. I was wondering how fast the Rex could go at the highest estimate.
I think Rexes were ambush hunters, there’s no way they could run down prey to exhaustion.
no need to be faster than your prey if you got more stamina and T.Rex had both smell and sight good enough to find it's prey again anywhere if it dissapeared
It seems that my own personal theories on T.rex’s speed were correct it helps that the paper took the tail and other muscles for shock absorption into account like I did.
It's still faster than most of humans 😮😮, maybe just usin bolt for few seconds can be as fast as a tyrannosaurus rex😮😮!
I think the speed estimate for sue is a little high, this individual was huge and although the T. rex is more muscular and more mobile than a elephant (which the large individuals can’t move more than 10 mph) it still huge. I personally will stick with 6.2 mps or ~ 14 mph based on Larramendi speed formula.
I can't imagine a multi-ton creature leaving the ground with all feet, like a galloping horse, in the air though I may have misheard the video.
The fact that 7ms^-1 is a conservative estimate is incredible
Dwarfs an elephant, had the appetite of a lion, you would feel it before knowing where it would be coming from and when you would see it, you can't outrun it... T. rex is long dead and dead forever but just thinking about its stats makes my bones chill.
Given that its prey were big but slow(most of the time) and the fact that it mostly relies on ambush, T.rex didn’t really need to run
I wonder why there are so many more specimens of T-rex compared to other megatheropods. Is it just more excavations/digs in those regions, better fossilization conditions, or there were just more of them?
Successful species
I bet if you need to outrun a T. rex doing zig zags would be in your favor. Can’t imagine an animal that big/ fast being able to turn well
What about the air sacs? How would they assist with speed?
T Rex 2023: I've become bigger
T Rex 2024: And now i've become faster.
Haters: Cry
It doesn't need to out run you. It just needs to out last you in that run.
(note i would love to see how dinos either megatheropods, Sorapads or others would have survuved in Medieval times ( or around that 1000 year time span). Given how humanity evolved with weaponry and others things as well. ( i mostly just want to here someone talk about Knights fighting dinos)
I'm actually working on a full book series exploring that very concept...
@@TheVividenreally? Excited to see it and read it.
Any updates of Bertha rex?
Nothing yet!
I misread the tile as:
'How FAT was Tyrannosaurus rex?'
So we say "long distance persuit" but how long would they be able to keep up those speeds? Minutes?
larramendi's formula gives Jane a speed of 62 km/h
It blows my mind that some of the studies didn't even include the caudofemoralis, the most powerful muscles working the animal's legs. 🤨🤨🤨
Just wanted to note that bears being able to run at 15.6 m/s is almost certainly an exaggeration too. It's a popularly cited speed estimate like 25 mph for elephants, but bears just don't have the cursorial anatomy to run that fast.
no
its not grizzly can hit 35mph
Yes it is and no it can’t.
@@toothclaw6985 so you calling all the anmail planet and discovery channels show liars
Yes I am, actually. How many sources repeat a claim doesn’t matter, it’s where the claim comes from that matters. And bears running at 35 mph comes from old sourced using unreliable methods of estimating speed.
@@toothclaw6985 I've seen them chase down elk and wild horses and white tail deer
Still terrifying.
I remember years ago reding an article that even if they could run fast they wouldn't because if they tripped the mass of the animal could break ribs, arms, and vertabrae...
Outdated
T-Rex most likely hunted similar like wolf they lived in pack and hunted they prey by drained their stamina
The thing about being the biggest and baddest is that you dont need to hunt to survive you can take foods from other and scavenge since there were no shortage of dead prey
there really would be quite the shortage if the only animal in the environment capable of taking down the large prey didn’t take the large prey down lmao
Well it depends on what the large theropods are going after.
@manzac112 t rex was a long distance runner
Speedy giant
You can't run away from it 🦖
It probably was equal to an African elephant, but yeah, some individuals could probably be a little bit faster than an elephant. I’m also pretty sure that it’s also faster than its prey such as triceratops and edmontosaurus. And yes, it was probably an ambush predator because of its body especially with the big boys, such a Sue, Scotty
Totally wrong t rex is faster.!
@@rodrigopinto6676 how am I wrong?

I just don't buy these T Rex speed estimates. There is simply no way Jane would have trouble catching up with a human sprinter. Maybe the adult Rexes weren't as fast, but there is no way the younger ones weren't in same league as an ostrich when it came to speed.
I guess the allosauroids didn’t have to run all that fast if their prey was giant sauropods that act like whale falls when they die😂
True haha
*Camptosaurus leaves the chat*
@@archosaur_enjoyer824*Ceratosaurus enters the chat* as the potential predator that would’ve been powerful & fast enough to hunt Camptosaurus & Dryosaurus.
Keep in mind the top of the weight estimate for allosaurus is around 3 tons, for an adult rex that is almost 9, meanwhile the length for those weights are 9.7 and 13m in case of rex. It was way more slender so it likely didnt need such a specialised bone structure to support its weight while running. The different researches puts Allosaurus at the following speeds: the oldest one from 1981 is 12.8-14.7m/s estimate, was based on tracks, the rest 6.7-10.7 m/s, one at 9.4m/s, one doubts anything above 8m/s.
So by all means, it wasnt slow.
T rex didnt even need to like like its modern day predecessor the tiger it's roar it theorized to have stun effect.
Something I like to note that really annoys me when ever someone brings up a large animal be it a T rex or even Godzilla everyone jumps to oh it would be slow or oh its heart wouldn't work because its too big. Really we are not comparing humans that are bigger, a really big animal would could just have some adaptation to help them out, after all even a blue whale sized human strictly stuck in the ocean still wouldn't work yet blue whales exit.
Here's a thought: T-Rex's maximum speed is, essentially meaningless. All that matters is that an adult T-Rex runs, over time, faster on average than the prey it's attempting to eat. After all, speed is relative
Anything new on the true size of T Rex?
It's definitely the largest terrestrial predator to ever walk on earth.
Hype
I believe sub-adult and juveline T-rexes were likely fast runners which enabled them to catch faster prey,while the adults were probably just "fast walkers" that potentially feasted on much larger and slumbering prey as a last resort,but most of time using their sheer size to steal kills from smaller predators or simply scavenging on already dead carcasses,their large size again allowing them to get ahead of the competition.
Tyrannosaurus probably wasn’t a scavenger most of the time, given its adaptations and since it was faster than literally all the viable prey in its environment I think chasing or even fighting head on was viable for it
@@Chadhadiya-yc2ct If there is free food,it's very difficult to say no to it from a primal evolutionary perspective.
@@mihirshetye4624 this is true but free food isn’t going to be all that common when the only predator capable of creating more free food is the scavenger - Tyrannosaurus was likely an opportunistic predator which is what you are saying, it is simply that the frequency of hunts will be far more common than what you said
@@Chadhadiya-yc2ct That will depend how much food the adult T-Rex can obtain via scavenging or stealing,if there is less of that to begin with,then I do believe that hunting would be a natural thing to do and certainly this dino was tailor made for that with all its evolutionary adaptations.
I was not trying to somehow reignite the old hunter vs scavenger debate about the T-Rex,just stating that the adult(or even Sub-adult) T-Rex could have easily gotten its way when it comes to stealing kills from smaller predators or gotten the first dibs on any carcass that it came across.
As for speed,yeah,the adult T-Rex was far more likelier to be a fast walker rather than a true runner given its sheer bulk and chances of injury when sprinting,but then again its prey of choice aka Hydrosaurs and in rare instances Triceratops would been even slower and less agile.
Finally,the potential segmentation between juvenile and adult Rexes when it comes to prey preferences would have also lessened the competition between the age groups and thus aided the overall spread of their species.
@@mihirshetye4624 the sheer amount of calories Tyrannosaurus required wouldn’t have been sustained by scavenging from smaller creatures even while hunting occasionally lol, also the niche partitioning between adults and juveniles comes nowhere into this (because juveniles were the mid-sized predators in the ecosystem, and adults would prefer to hunt much larger prey to legitimately sustain themselves as opposed to just stealing a tiny kill that wouldn’t provide it enough)
So Tyrannosaurus rex would be like big cats like ambush but not built for long chases?

Yo sorry this isnt a question about the video but How heavy was the Giganotosaurus carolinii? Google says weird shit and my books says 5-7 tons. But many people say Giganotosaurus was the biggest Land predator. Can anyone help me.
5 to 7 tonnes sounds about right. The upper length estimates for Giganotosaurus put it at maybe a metre longer than T-rex but it would have been a lot lighter. T-rex is definitely up there, with Sue coming in at about 41 feet, but there are longer therapods.
The difference is T-rex is an absolute unit. Carcharodontids like Giganotosaurus are tall and long, but light. They're not chunky. They're walking steak knives, not sledgehammers. T-rex on the other hand is a tank some estimates go as high as 11 tonnes they are jacked. To put it in human terms, if Giganotosaurus is the 6 foot 8 basketball player, T-rex is a 6 foot 4 linebacker.

so, what about their prey's speed like triceratops and E.annectens? are there any recent studies on that?
The biggest and slowest of its family. As adults
"Slowest" wrong 😂
@@rodrigopinto6676 What tyrannosaurid is slower than T. rex?
@@MastaBaitaAmbatukam none, also that’s quite the interesting name 😂
@@rodrigopinto6676 no he’s right all the other tyrannosaurids are built the same and more gracile, of course Tyrannosaurus is beating them all in a fight though
Why do people think that a predator with a built in AC unit in its head couldn’t run, I guess elephants don’t run either 😂😂😂😂
It was slow AF.
No
Jane' highest speed is estimated at 62 km/h
