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"
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.
Fr! Paleontologists should exercise more caution before naming small tyrannosaurids as new species. Given the variability in growth stages and the fragmentary nature of many discoveries, it's important to gather more fossil specimens before making definitive classifications. By rushing to name new species based on limited evidence, we risk misinterpreting juvenile or incomplete specimens as entirely new genera. A more thorough approach would provide a clearer picture of tyrannosaurid diversity and evolution.
I'm tired of seeing new species being announced, only for them to later turn out to be juvenile dinosaurs of already known species. Paleontologists should be more cautious and focus on finding more fossil specimens before naming small tyrannosaurids as new species. It's crucial to have a more complete picture to avoid misclassifying immature dinosaurs as entirely new genera. A careful approach would help prevent these repeated missteps and provide a more accurate understanding of dinosaur diversity.
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.
@@DylanZombie Become a paleontologist and discover a new species before it's too late or become really rich to fund a bunch of paleontologists and tell them to name a new species for you
The fact that Tyrannosaurus had the most powerful bite of any land carnivore, and its prey were STILL able to shrug it off, survive the fight, and recover is insane. I think a similar video for Hadrosaurs and Ceratopsians is overdue!
Thats because, same as other bone crushing animals nowdays, its big bite force was for work AFTER its prey was killed, so it could eat everything from it (same as Hyenas, Crocodiles and Tasmanian Devil while having other ways to kill prey)
@@Kaiserhabicht74 Dryptosaurus was a Tyrannosauroid ('superfamily'), but was not a Tyrannosaurid (the more derived 'family' within the given Superfamily) and this video above is only about members of the 'Tyrannosauridae', which he talked about at the beginning and even showcased therein a phylogenetic tree which coincidentally featured "your" Dryptosaurus as sitting outside of the Family.
To be fair, we don't really know how big Zhuchengtyrannus could get since it's only known from very fragmentary remains from a single specimen. But seeing how big the herbivores like Sinoceratops & Shantungosaurus were getting I wouldn't be surprised if it was pushing Tyrannosaurus-size. There's also fragmentary remains of a giant Tyrannosaur from the Udurchukan Formation in Russia.
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 :)!
I am impressed by the clean, super professional, accurate and well-cared presentation, and for the effort to get it right. It's evident when people make things with love. Thumbs up and subscribed of course...
I like this kind of videos, with good graphics, good sound, a lot of good great quality information, Excellent narration, they don't overuse technical terms and explain it all 10/10🎉

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
These videos are so interesting and genuinely keep my attention for the whole thing. These videos are so educational and I’m sure everyone (me included) are waiting for learn more from you! Maybe videos like these on raptors and pterosaurs would be a real grab! Keep up the good work!
Ix love this series for just every group, not just dinosaurs and not just extinct. Its cool to see animals smallest to largest and see all the differences
As a dinosaur enthusiast since childhood, I can say that I love the videos you post. Keep it up ! You're making the kind of content I dreamed of when I was little.
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.
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!

Thank you so much for these videos, they’re super entertaining and interesting! I am so freaking happy I found this on my fyp page! New subscriber and avid watcher! ❤️✨
Sauropods are an incredibly diverse group of dinosaurs you would have to make an all diplodocids video or something because thats a family of sauropod like tyrannosauridae is a family of therapod
That would be way, waaaayy too many genera all at once. An insane undertaking! Objectively, it would be a much better idea to rather break the Sauropoda down into several separate distinct groups, such as Diplodocids, basal Sauropodomorphs or Titanosaurs, and gradually produce individual videos about them one at a time.
Hi Eric, I did not know whether to put this here or on your Patreon? But your 2 videos got me thinking & reading about the Western Interior Seaway. A discourse or 2 by you on the fauna of Laramidia and Appalachia would be quite an undertaking and at the same time fascinating--especially with your graphics and background music! The other subject I am very interested in is the Danian stage since that is immediately after the meteor reshuffled the deck and you and I started out as little rodents. Ok, I'm out of ideas for you, lol, 😉. Thank you for make these top notch 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)
hey i watched this video and the spinos vodep it's amazing, amazingly animated and explained you should try to do all abelisaurid and all mosasaurs or focus on formations like kem kem beds or hell creek that should be great !
I watched Land Before Time at 4 yo and Jurrassic Park one year later (yes I was 5) and read dozens of dinosaur books as a kid. This channel has awakened my inne dino-nerd again, with the overview over all the new species that has been discovered since! I am amazed!
Subscribed because you're a fellow dinosaur lover from SE Asia (was wondering, are they Thai? Cambodian? Indonesian? until I looked at your channel info)
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!
13:34 the fenestre serve not the purpose of reducing weight but did serve as base for facial muscles, mainly jaw muscles. More fenestre meant a stronger and more accurate bite force
17:37 thats not true, that title goes to Psittacosaurus And Siats was more probably carcharodontosaurid than megaraptoran Based on that there are not found any megaraptorans in North America and that the time of Siats, there are still 3 carcharodontosaurids Undescribed from Woodbine Formation Undescribed Allosaurus-sized from Wayan Formation (that maybe was partly piscivorous) And Labocania (and yes, Labocania lived 94 mya which basically says its carcharodontosaurid)
And interesting too is Tyrannosaurids only have been found in the Northern Hemisphere as the Southern Hemisphere was occupied by different kinds of top predatory species but the north was completely taken over by the Tyrannosaurids
Maip is still kinda related to tyrannosaurids? And africa was really I mean really close to usa so maybe we could find some tyrannosaurids that crossed into africa, Australia,south america, antartica or india just like abelisaurids did on the northern hemisphere including carcharodontosaurids and spinosaurids
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 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.
It's awesome how we got agile Tyrannosaurids and robust Tyrannosaurids, it really shows you how diversified they are. I love this video because it's about my favorite dinosaur and its relatives, phenomenal quality as wells :D
19:15 is supposed to say "Hell Creek Formation, 66 MYA". It completely missed my eyes.
Thank you everyone for pointing out!

Sauropods are an incredibly diverse group of dinosaurs you would have to make an all diplodocids video or something because thats a family of sauropod like tyrannosauridae is a family of therapod
@@Breviparopus thats true.
That would be way, waaaayy too many genera all at once. An insane undertaking!
Objectively, it would be a much better idea to rather break the Sauropoda down into several separate distinct groups, such as Diplodocids, basal Sauropodomorphs or Titanosaurs, and gradually produce individual videos about them one at a time.
@discobolos4227 I made that when I wasnt that educated on phylogenetics lol 🩷😭
I would love to see one of these videos for Abelisaurs :D
I second this
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!
Yesss ive been desperately waiting for another factor trace video, i jumped for joy when i saw this one! Please help making these videos! ❤️
Bro, acabo de descubrir tu canal y me encanta, sigue así.
We need more of this !! it's amazing 20min of knowledge
Hi Eric, I did not know whether to put this here or on your Patreon? But your 2 videos got me thinking & reading about the Western Interior Seaway. A discourse or 2 by you on the fauna of Laramidia and Appalachia would be quite an undertaking and at the same time fascinating--especially with your graphics and background music!
The other subject I am very interested in is the Danian stage since that is immediately after the meteor reshuffled the deck and you and I started out as little rodents.
Ok, I'm out of ideas for you, lol, 😉.
Thank you for make these top notch videos.
Bro I love this series and hope you continue it
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)
A worthwhile watch. Thanks for posting.
This is absolutely amazing, please continue to make more, where do you get your music from?
how are you not a popular youtuber????? youtube needs to get this guy verified
Well done. Is there any chance of doing a video on Megalosaurids or the Allosaurids, particularly the Carcharodontosaurids?
One word UNDERRATED!!!
hey i watched this video and the spinos vodep it's amazing, amazingly animated and explained you should try to do all abelisaurid and all mosasaurs or focus on formations like kem kem beds or hell creek that should be great !
i have some fossils if you wants illustrations for your videos
This is so well done!
I watched Land Before Time at 4 yo and Jurrassic Park one year later (yes I was 5) and read dozens of dinosaur books as a kid. This channel has awakened my inne dino-nerd again, with the overview over all the new species that has been discovered since! I am amazed!
I like your video format. Subscribed.
Good job. I stargaze at these vidoes your talent is much appreciated.
Thank you! I appreciate it
Thank you for the videos and information you provide us, I appreciate your effort ♥️
Love this video, hope there will be one on carcharodontosaurids next
No, the next will be the coolest Dinos of them all, the Alvarezsaurids. :D
@discobolos4227 lol, would be nice
Subscribed because you're a fellow dinosaur lover from SE Asia (was wondering, are they Thai? Cambodian? Indonesian? until I looked at your channel info)
I love that you show the amount of material used to describe a new genus/species 👌😋🦖
Incredible video. Great edition and topic!!
Hopefully, we get to see many different species with a video like this!
Would love to see Hadrosaurs and Dromeosaurs!
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!
Please make more of these i subbed!
How do u edit these videos so well, Id love a full process overview or tutorial.
Also now Asiatyrannus got discovered as well
amazing channel everything well explained
Much appreciated!
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.
I love these videos. Especially because I love paleontology.
13:34 the fenestre serve not the purpose of reducing weight but did serve as base for facial muscles, mainly jaw muscles. More fenestre meant a stronger and more accurate bite force
17:37 thats not true, that title goes to Psittacosaurus
And Siats was more probably carcharodontosaurid than megaraptoran
Based on that there are not found any megaraptorans in North America and that the time of Siats, there are still 3 carcharodontosaurids
Undescribed from Woodbine Formation
Undescribed Allosaurus-sized from Wayan Formation (that maybe was partly piscivorous)
And Labocania (and yes, Labocania lived 94 mya which basically says its carcharodontosaurid)
i love your pronunciation of thanatotheristes. very addictive.
I would absolutely love a video like this but with allosauridae
Love your videos, next I think you should do every charcaradontosaurid in existence
For money! :)
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 (:
And interesting too is Tyrannosaurids only have been found in the Northern Hemisphere as the Southern Hemisphere was occupied by different kinds of top predatory species but the north was completely taken over by the Tyrannosaurids
Yep, the Abelisaurids dominated the Southern Hemisphere as apex predators in the late Cretaceous.
@ Likr Carnotosaurus was king of South America, though down here in Australia we had Megataptorans
@@discobolos4227 Maip: Hold my beer
Maip is still kinda related to tyrannosaurids? And africa was really I mean really close to usa so maybe we could find some tyrannosaurids that crossed into africa, Australia,south america, antartica or india just like abelisaurids did on the northern hemisphere including carcharodontosaurids and spinosaurids
more of these please, sauropods, raptors, stegos etc
Update: Labocania is now known to be a Tyrannosaurine Tyrannosaurid
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.
Just a question, is 19:16 meant to say nemget formation?
Yes! I can't believe I missed that mistake, it's supposed to say "Hell Creek Formation, 66 MYA".
Thanks for noticing
please show how you edit your videos, or which company edits them for you, great editing
Can you do ankylosaurid documentary? I love your dinosaur documentary.
♥
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!
Will you be doing more videos like this exploring families? I’d love to see hadrosaurs and other herbivores
It's awesome how we got agile Tyrannosaurids and robust Tyrannosaurids, it really shows you how diversified they are.
I love this video because it's about my favorite dinosaur and its relatives, phenomenal quality as wells :D
I would love to watch a video on the Therizinosaur family pls ❤
That's a great idea, thanks!
Excellent video, a pleasure to watch, the most interesting presentation, can I have some crocodylomorphs now please?
This channel deserves milions of subscribers! Such well made and accurate video, congrats man
Appreciate that! thanks
