Every Tyrannosaurid, explained.

- Опубліковано 28 чер 2024
- Tyrannosaurus rex is a name we're all familiar with, it's the most popular dinosaur and is most likely the one that introduced us to the wonderful world of paleontology. But do you know that T. rex isn't the only Tyrannosaur? Tyrannosaurus, Daspletosaurus, Gorgosaurus and others are all members of the Tyrannosauridae family.
The Tyrannosauridae comprises of 18 genera of tetanuran theropod dinosaurs, but some of which are no longer a valid taxon and some others have disputed validity.
All 18 genera of those dinosaurs, however, are included in this video. Listed and explained one by one from the smallest in size all the way up to the largest.

19:15 is supposed to say "Hell Creek Formation, 66 MYA". It completely missed my eyes.
Thank you everyone for pointing out!
Please do it for therizinosaurs next
I think Tyrannosaurini may have originated in America, mostly because the oldest known Tyrannosaurid, Lythronax originated here as well. T. Rex's prey were especially adapted to kill T. Rex. The Hadrosaurs were massive and heavy, Triceratops and Ankylosaurs couldn't have been just toppled by the Rex, and Alamosaurus was just massive.
Though, I can see the possibility that Tyrannosaurus Rex could have come from Asia due to how successful it was in America, I mean we have 40+ fossils of T. Rex. But where I think the migration thing falls short is where are there migratory fossils? The ones where they were going up to Alaska, and leaving Alaska? Also it's prey was adapted to T. Rex really well.
Fun Fact: If we go by the rules of nomenclature, Tyrannosaurus rex should have been named Manospondylus gigas as Edward Drinker Cope was the first to give the latter name when he found Tyrannosaurus fossils in 1892, 13 years before Henry Fairfield Osborn gave the name Tyrannosaurus rex. But because Tyrannosaurus rex proved to be the more popular name and that Manospondylus gigas has not appeared in scientific literature for over 50 years since its introduction, the latter name has since been declared nomen oblitum (forgotten name). By extension, Tyrannosaurus rex is now considered nomen protectum (protected name). This goes to show you that even paleontologists aren't immune to "rule of cool"
Two horrible racist eugenicists name this big Theropod, which name should we go with? I know Tyrannosaurus rex, and thank god they did.
@@SmashBrosAssemble Idk why that was important to point out. It was over 100 years ago, so who cares
@@StormcloakGuard
Sure should we forget about WW2 & Holocaust as well cause it was nearly 100 years ago? You utter cretin
That’s a nice bit of information, thanks!
Dimetrodon is also in the same case, were it name isn't its real and valid one, and its true, valid name is actually Bathygnatus.
It extremely rare and exceptionnal such cases where an animal have two valid genera name and yet it's the second, junior synonym which is used massively even by serious professional researchers currently, solely because this name is more famous and popular than the first. And as such, researchers decide to use it anyway and break/made an exception to the rule because they know as useless and dead in the egg it will be advance to even try to changed public's mind and learn them the actual valid name of the animal.
As everyone know what happen with Brontosaurus many decades after it was judge to be Apatosaurus, before on top of that end up actually be valid anyway.
Without any doubts one of the greatest middle finger into the face of researchers and Paleontology ever made by Life itself 😅😂
Aside "T-Rex" and "Dimetrodon", the others taxa in this same situation are really few in number.
"Youre invalid, he is invalid, WHO ELSE IS INVALID?!"
Everyone who was described with unclear specimens, I suppose 😅
*dakotaraptor walks in* hey there
I'm an invalid! 😂 (I was born with spina bifida)
@@mr.jglokta191you are not invalid!
You
I absolutely adore how paleontologists seem to be on a mission to give tyrannosaurids the edgiest names imagineable.
Death reaper? Gore king? Dreadful lizard? Monstrous murderer? Terrible tooth? Bistahi destroyer? My inner child is celebrating.
Other Tyrannosaurs: "Le typical fast predator with a good bite and sharp senses"
T Rex: *DOOM SLAYER*
Funny how the moniker it was affixed a century ago still holds true, King of the Tyrant Lizards.
I feel that it is worth mentioning that the validity of qianzhousaurus is still fairly contested as they may simply be an older specimen of alioramus
Oh, and also, please consider doing hadrosauria next
Paleontologists: We discovered a new micro species of Tyrannosaurid!
Adult version: Hold my beer
Gonna be one heck of a list, but I'd suggest doing Carcharodontosaurids next. (PLEASE I BEGG)
fun fact: teratophoneus was in Jurassic World : Fallen Kingdom as a corpse near control center and it's considerd canon in universe
Well, it isn't considered canon, it IS literally canon justly thankfully because it at least appear onscreen for some seconds (even dead) on the movie.
Anything which appear inside the movies (orally or visually) are definite canons to the lore and universe of a franchise.
(Like the fact that JP:TG game events are canon as well, because the volcano of Nublar is inside the movie mentioned as Mount Sibo, which was first ever dropped in the 2011 game. Implying what that imply.)
So, yes, Teratophoneus is canon to the movie's lore, thus sadly as an extinct species, unless it made a living appearance in a post -2018 media. But that very unlikely that happen ine day.
There was another dinosaur, an ankylosaur, Peroloplites, which was planned too, but it only appear briefly in the trailers of the movies and was entirely cut from the final version of it.
And as an effect, it isn't canon to the movies.
Dude i just love your videos!
They're so well made, and i can clearly see you did a lot of research to make them (and you used modern studies which is great!).
I'm really glad of this series, because i can actually learn more from you for each dinosaur familly and group.
We need more people like you, keep it up :)!
Thanks a ton! I'm eager to expanding this type of videos to more dino families. I'll try to keep the quality up!
@@FactorTrace now can you make a video with Carchadontosaurid video?
Mate, you're an absolute legend. These videos have been fantastic, feel free to do more videos on more obscure animals that not many people have talked about. Great work!
What a wonderful tribute to the science about the Tyrannosaurids.
Yo! Charlie!
Tyrannosaurus - The King of the Dinosaurs
Tarbosaurus - The Khan of Mongolia
Zhuchengtyrannus - China’s Prehistoric Tyrant
Daspletosaurus - Fear Incarnate
Bistahieversor - The Destroyer
Dynamoterror - Terror Incarnate
Gorgosaurus - Dreaded Monster
Albertosaurus - Ruler of Canada
Thanatotheristes - Bringer of Death
Terataphoneus - Horror of Kaiparowits
Qianzhousaurus - Long Snouted Hunter
Lythronax - The Bloodied Tyrant
Nanuqsaurus - Terror of the Frozen Tundra
Alioramus - Pinocchio Rex
Actually Qianzhousaurus is the real Pinocho rex because is his official nickname.
Ironic that Qianzhousaurus is the only one of all this bunch that the name is funny and laughable, while the others are made up to made them feel serious, bloodthirties and terrifying beasts to not mess with.😂
Once again, you made an incredible scientific video about dinosaurs. I loved this one! I love the tyrannosaurs, especially the tyrannosaurids! Again, I'm impressed by the editing, the data, the drawings, skeletals and reconstructions of the tyrannosaurids. I've read that more tyrannosaur papers will come yet in this year of 2024. We all will see what more studies and data about them will be. Very well done again, Factor Trace! Bravo! I'm looking forward to your next scientific video! :D
Thank you for your support! I appreciate your kind words, it is what keeps the channel going
I would love to see one of these videos for Abelisaurs :D
I second this
Great video! The recent paper that described T. mcraensis actually suggests (in my opinion) that Tarbosaurus should actually be classified as a species of Tyrannosaurus (Tyrannosaurus bataar) as originally envisioned in 1955. I think this because the T. mcraensis paper notes several times that this newly described species appears to share an equal number of characteristics with both T. rex and Tarbosaurus, so if we are to be consistent with our taxonomy, either T. mcraensis should be "upgraded" to its own separate genus (but closely related to Tyrannosaurus) or Tarbosaurus should be absorbed into Tyrannosaurus. Also its worth noting that to this day whether Tarbosaurus is its own genus remains a debate, certain prominent Tyrannosaur experts such as Thomas Carr have always maintained Tarbosaurus as Tyrannosarus bataar. Finally the paleontologists that pushed the idea that Tarbosaurus is its own genus mostly based this on their hypothesis that its actually more closely related to Alioramus then to T. rex and that similarities to T. rex are a result of convergent evolution in both animals achieving "gigantism". Since then new discoveries have shown that Alioramus belongs to its own "tribe" and its not more closely related to Tarbosaurus then T. rex is.
I think the autapomorphies seen in Tarbosaurus is prominent enough to warrant a separate genus. While it is true that after the discovery of Qianzhousaurus, Alioramus is no longer commonly accepted as Tarbosaurus' closest relative, it still doesn't disprove the validity of the genus.
In the description of T. mcraeensis, the authors noticed similarities between it and Tarbosaurus and Zhuchengtyrannus but did not put to question the validity of the genera.
These videos are sooooooo well made, and the narration is top notch.
As someone with both great interest in motion design and paleontology, this channel is a godsend. You should be proud of the work here, it's awesome!
My favorite paleo channel rn, genuinely fantastic videos
Holy shit man! How can you be so artistic and talented at the same time?! Bro keep this up you deserve more views. Your reconstructions are just amazing (especially ones depicting behavior)
I can't wait for the Carcharodontosaurids video, Tyrannosaurs and Spinosaurs got theirs so now it's time for the shark toothed therapods
Please make more of these! I love this
Actually so hyped to watch this, lol.
After watching the video on every genus in the spinosaurid clade on animals, I’m genuinely surprised this is on UA-cam for how high quality it is.
I really liked these last videos, they contain a lot of cool information about these dinosaurs, even for those who have little information, you can gather more information about them and I really admire them, another thing is that we have the video on the tyrannosaurid family, the spinosaurid family , but will we have an "Every carcharodontosaurid, explained" in the future to round off the mega theropod family with a flourish?
Megalosauridea ont aussi quelques gens qui sont des mega theropodes tous commes les abelisauridae donc non les carcharodontosauridae ne vont pas conclure les familles de mega theropode et j’ai aussi oublié Saurophaganax aussi de la famille des Allosauridé
Glad you like them! The carcharodontosaurids video (and other iconic families) is coming in the future!
Yesss ive been desperately waiting for another factor trace video, i jumped for joy when i saw this one! Please help making these videos! ❤️
A worthwhile watch. Thanks for posting.
YESSSS, I BEEN WAITING FOR THIS
Thank you for the videos and information you provide us, I appreciate your effort ♥️
Well a week ago, a new specimen of juvenile Tyrannosaurus was actually uncovered by three children and nicknamed Teen Rex and deserves to be on the new documentary for museum theaters. Edge Science was explaining the Teen Rex was either Nanotyrannus or just a juvenile would be difficult to confuse many people to trying understand the truth about the T. REX growth.
¡Maravilloso! Excelente trabajo 🤩👏🏼
New Factor Trace Video!!!
These are the best!
you should make a video on carcharodontosaurids or dromaeosaurids next
He's done Spinosauridae. He's done Tyrannosauridae. Now please you have to do Carcharodontosauridae
Can you do ankylosaurid documentary? I love your dinosaur documentary.
NEW FACTPR TRACE VIDEO WE WON!!!111!111!!! keep making these btw i loved the spinosauridae vid😭😭
Very very well done. Subscribed 🎉
You should make an Every carcharodontosaurid, Explained or Every Abelisaurid, Explained video, and also great video
Nice and interesting video. The Tyrannosaur family is such magnificent! Make A documentary about the carcharodontosauridae, for complete the 3 family of the greats: Spinosaurus, Tyrannosaurus and Giganotosaurus
The carcharodontosauridae is coming! I will be collecting the great families like the infinity stones 😂
@@FactorTraceAfter that video, you should make one on dromaeosauridae.
@@FactorTracedidn’t you already do spinosauridae?
@@NetheriteGuy14-vs7nenon les megalosauridea et abelisauridae
@@SussyFloppaYt Yes he did.
This is such a good video!
Ame este video, gracias ❤️🦖
Good job. I stargaze at these vidoes your talent is much appreciated.
Thank you! I appreciate it
I love your videos keep it up
Lets gooo new upload!!!!!!!!
For a Creature that needs a $hit-Ton of meat every day just to be able to wake up I think we can forgive 'Ole T-Rex for Chowing Down on one of it's dead/killed comrades occasionally
Finally, was waiting for this
GOATED Video
Babe wake up! Factor Trace uploaded another beautiful video!
you are my favorite youtyuber and i love your videos and i know a lot of dinosaurs everything you say i know but it's fun to see your videos🦕
Wow, thanks! You're a true paleontology fan
@@FactorTrace thanks (:
I love this channel. Thank you for these videos!
I love all of these designs
I hope Carcharontosauridae is next :DD
Contrary to common belief tarbosaurus skull was actually extremely robust. Front of the head was pretty much equally robust to tyrannosaurus while back of it was narrower. This made tarbosaurus skull very similar to Daspletosaurus skull. The narrow head comes from a reconstruction of ZPAL MGD 1/4 from Hurum and Sabath paper from (2006?), reconstruction was based on a rather incomplete material, but more complete individuals show that it's skull was rather robust. Tarbosaurus was generally a rather robust animal as even juveniles are quite heavily built. It's a shame that it's quite understudied since there are around 150 individuals known. Great video by the way! I really adore that the tyrannosaurus has colors based on the rebor tyrannosaurus figurine😂
At first i was really inlove with the every spinosaurid video and this is just the ice on the ice tea
You have amazed me with the information and summary about the Tyrannosauridae Family. The effort and dedication you put into this video is very noticeable. I recommend that they make one from the Carcharodontosauridae Family.
Greetings Factor Trace 👋
Wow, thank you! Carcharodontosaurus video is coming in the future
Amazing work!
Thank you! Cheers!
Even adult tyrannosaurus rex are more agile than any other therapods
I was about to do a time stamp comment but then I accidentally pressed the arrow which skips forward a video and the comment reset. I'll be back tomorrow to try again, feel free to do it first though. (Also i made the mistake of checking the time)
When carcharodontosauridae
Coming in the future!
@@FactorTrace ty man
Well now that you’ve done tyrannosauridae, you’ve got to do Carcharodontosauridae. I personally think they are cooler.
All carcharodontosaurids explained next
Hopefully, we get to see many different species with a video like this!
Would love to see Hadrosaurs and Dromeosaurs!
Nice video ❤️
Thank you for continuing the series! You're the best!
EDIT: Zhuchengtyrannus is HIGHLY possible to be a nomen dubium; a chinese propaganda of "we also have tyrannosaurids" since its only came from incomplete holotype of upper and lower jaws.
You're welcome! That's an interesting theory, whilst it is true that unfortunately politics have made its way into science, I don't think paleontology or specifically, the description of zhuchengtyrannus is one of it.
Zhuchengtyrannus was described by a team lead by a renowned British paleontologist, Dr David Hone.
Besides, China already has its iconic tyrannosaur, the tarbosaurus. On top of that, the lineage that gave rise to all giant tyrannosaurus most probably originated from China. Most basal tyrannosauroids are found from Asia.
Dromaeosauridae and Troödontidae next please
They're on the list, coming in the future!
@@FactorTracewhat about any family’s of ptersauria, prehistoric marine life and prehistoric plants?
@@garrettlich7140 Dinosaur's families>>>>>>>>>
Well done. Is there any chance of doing a video on Tyrannosauroids or the Allosaurids?
I know that this was just uploaded (these videos are underrated) but if your ready for another one, just in case, I have a few theropod recommendations:
Alvarezsaurids (including alvarezsauroids)
(ex. Xiyunykus, Albinykus and Xixianykus)
Compsognathids
(ex. Procompsognathus, Xunmenglong and Sinosauropteryx)
Also, is there a chance that a video of theropods of uncertain affinities can be uploaded?
(ex. Aniksosaurus, Xinjiangovenator and Bicentenaria)
I would love to watch a video on the Therizinosaur family pls ❤
That's a great idea, thanks!
This video was so good maybe you could do abelisaurids or charcarodontosaurids next
I actually laughed out loud when Nanotyrannus came up
Nice video ♥️
This is really cool 😎
In addition, there is this one dinosaur, a Tyranosauroid named guanlong, part of the proceratosauridae family, an ancestral group that branched into Pantyrannosauria, then into Eutyrannosauria, which split into the genus Dryptosaurus and the family Tyranosauridae, which then gave rise to the subfamilies albertosaurinae and tyranosaurinae, and then the groups alioramini and daspletosaurini, which finally gave rise to the tribe tyranosaurini, and then the genus tyrannosaurus and its type species T.rex, which ultimately became the most popular species of dinosaur, being the only one to not only be referred with its genus name, but also the species name, back to this Jurassic theropod, guanlong, when it was first discovered, many scientists debated each other’s explanations, this small, possibly feathered dinosaur with a cool crest that might be colourful to scare away competitor males and attract females, was said that its an ancestor of many species such as Tyrannosaurus rex, others say its actually a synonym of a young monolophosaurus, another Jurassic genus of dinosaur, and then guanlong is misidentified as a new genus in 2006, but its found that guanlong had adult traits, so its most likely a separate genus, so yeah.
Please use more periods. That had to be one of the longest run-on sentences I've ever read.
Holy yap
I’m pretty sure th majority of Paleontologists still consider Nanotyrannus to be an invalid taxon, and is still considered a juvenile Tyrannsoaurus.
This is absolutely amazing please keep making more of these
I think there is one dinosaur missing from this same genus... We totally forgot about Appalachiosaurus since its also from the same family as tyrannosaurus and the rest of its nomen dubium and synonymous cousins
Appalachiosaurus is a tyrannosauroid, the materials assigned to it was initially thought to be a member of the albertosaurine, but the name "Appalachiosaurus" has not been erected at that time, so technically I don't think it was ever a tyrannosaurid. Plus, the phylogenetic analysis was poorly made in that study.
i love these videos they are so informational and easy to understand and i love the animation It's just top tier i hope to see more of Every ____ explained.
PERFECTION
This video is incredibly high quality and beautifully made, it presents the informations in a clear and understandable way and goes out of its way to show niche discoveries that paint a full picture of this incredible Family. Truly, it can't be praised enough.
I have just one thing to ask: I noticed some of the sketches that complement this video's segments are traced from popular artworks of renowned paleoartists, which I couldn't find in the sources. I think it would be wonderful if you could cite them, as they too are contributors to this wonderful piece of scientific communication.
Alright noted! You have a sharp eye for noticing that, the sketches are actually mixed and edited from the original artwork, it's impressive that they're still recognisable.
I'm adding the original artworks in the credits!
This is so incredible! Can a triceratops video be considered
Tyrannosaurid size (basically their weight)
19th Raptor rex: 40 - 70 kilos
18th Aublysodon: 800 kilos
17th Nanotyrannus: 1 tonne
16th Alioramus: 700 - 1.2 tonnes
15th Deinodon: 1.3 tonnes
14th Alioramus speculative adult size: 1.9 tonnes
13th Teratophoneus: 2 tonnes
12th Qianzhousaurus: 2.2 tonnes
11th Thanatotheristes: 2.5 tonnes
10th Nanuqtyrannus: 3 tonnes
9th Lythronax and bistahieversor 3,3 tonnes
8th Dynamoterror: 3.559 tonnes
7th Albertosaurus: 3.56 tonnes
6th Gorgosaurus: 3.8 tonnes
5th Daspletosaurus: 3.92 tonnes
4th Tarbosaurus: 5.5 tonnes
3th Zhuchengtyrannus: 6 tonnes
2nd Tyrannosaurus mcraeensis: 8.8 tonnes
1st Tyrannosaurus rex: 12.5 tonnes
The 12.5 tonnes have been disapproven as exaggerations. T rex was 8-10 tonnes on average and 11.4 tonnes is largest estimate.
@@Uncledavemeltzer i use the maximum size, just like for gorgosaurus, albertosaurus and daspletosaurus for example since gorgo and alberta is 2 - 3 tonnes on average and dasple is 3.3 tonnes on average. 12.5 tonnes was the estimated 13m long T. rex and is also the new size of ed cope (yes ed cope has a buff). I am conscious that Normal is 8 - 9 tonnes
I would love you to focus more on the internal phylogeny of these dinosaur families and less on the organization of species by size.
I am so impressed with this… the quality. The effort. I am joining the Patreon ASAP. This is exactly what I need when I’m classifying my models, and attempting to organize correctly. I will do anything to show support. These are the most sleek and professional looking classification videos I’ve ever seen. Well done sir, well done. Please make a video on hadrosaurs? Ornithomimids, dromeosaurs, ANYTHING please.
Thank you! I really appreciate your support. I will continue to expand the every dino explained series and cover more families!
can you do all hadrosaurs next?
YEEEEEEES!!!!! Another one!!! 😍
Excellent as always! Lythronax is my fav, how about you?
Ooooo Im pretty early. I really wish someone would cover the entire Superfamily but this video is amazing anyway! Your high quality videos are amazing. I really do wish you success!
Glad you enjoyed it! A video on the whole superfamily would be a huge challenge to tackle, but we'll see in the future!
@@FactorTrace I understand!
I didn’t know Lythronax was so old!
Another very quality video, I subscribed to your channel immediately when I accidentally saw your video about Spinosaurid.
Hope you'll make a video about Titanosaurs, those strange land giants that Earth may never see again, and my favorite dinosaur clade.
Thanks, will do! I'm also fascinated by that family of giants
can you do every carcharodontosaurid explained?
Huh, I really thought Mcraeensis would be it's own thing. Oh well.
Anyway, I'd like to see a video on the rest of the Tyrannosauroidae family as there's still many interesting dinosaurs. The Carcharodontosaurids might be a good option, too.
This channel deserves milions of subscribers! Such well made and accurate video, congrats man
Appreciate that! thanks
Do Hadrosaurs! Please!
We need a Hadrosauridae video.
I Didn't Know Hyenas Are That Big😭
Do Azhdarchidae next!
THANK YOU FOR THESE VIDEOS!!! can't wait until you make one for allosauroids
Can’t wait to see the carcharodontosauridae
19:15 a small slip up I guess lol. Still a great video
Oh yeah, it's supposed to say hell creek formation 65 mya! That's a mistake
