The New Troodon That Rivalled Utahraptor In Size

Ever wondered where the news about the Troodontids has been? Well we have a new discovery to unpack which presents one of the largest deinonychosauria to exist! For now it is known as Fujianipus yingliangi.
Let us get into this!

Troodon larger than a bear is crazy 😭 the fact that these amazing animals once existed is amazing to this about.

[@TheOverseerDebates]

It’s amazing the remains that we continue to discover. Can’t wait to see what’s to come!

[@SuperBetaBuxbros.]

Bear would destroy 4 trooadons at the same time tho

[@albino-fish]

I’ll die laughing if achillobator was actually a troodontid that happened to convergently evolved Dromaeosaurinae like traits as a result of gigantism.

[@ANotSoPopularMan]

That'll be lovely

[@JohnSmith-ik8nt]

You would die laughing over that Holy autism

[@PotatopancakesOMG]

@@JohnSmith-ik8nthahah east there kdot

[@mylessmith9758]

Is it really that funny?

[@albino-fish]

You guys are looking into this comment way too seriously :/ The reason why I would think it’s funny because it would subvert a lot of people’s expectations. In a similar way to how brontosaurus was invalid for over a hundred years but was somewhat recently becoming valid again.

[@lectroeel6290]

There is also a troodontid tooth from a currently unnamed animal from the Prince Creek Formation. Tooth scaling is pretty unreliable, however most estimates put this animal at similar sizes to Utahraptor

[@RULER.EMU7878]

Not footprints again😭 I still remember that 20ton ceratopsian 😭

[@yaruyaru]

Agathaumas?

[@MonsterZilla856]

Troodon became valid again

[@Nrex117]

It was never really invalid it was just that a lot of the material that we thought was Troodon didn’t actually belong to it, which is still true, Troodon still exists but its only known definitive material is a handful of teeth. The bones that were once associated with it have been given their own genera however.

[@jacobniemann4756]

​@@Nrex117 Pectinodon, Stenonychosaurus and Latenivenatrix (the current largest Troodontid). Though it looks like that could potentially change based on this video.

[@Nrex117]

@@jacobniemann4756 Those are genera that were initially lumped into Troodon and all come from different times at least from the actual Troodon specimen which is a tooth taxon but not invalid even though being a tooth taxon as a dinosaur is about as useful as being invalid.

[@Pentecopterus]

I am a tour guide at a dinosaur track site in Utah. It is always amazing when I can point out the stories that our tracks show to our visitors

[@philipmurphy2]

Great content by The Overseer 👍

[@TheOverseerDebates]

Cheers, glad you enjoyed!

[@Sharktoz]

Very interesting. I think it's well within the realm of reason that a troodon species could get around this size. Especially considering the point you brought up about allosaurs disappearing. Adaptive radiation is fascinating. Also, you pronounced the name way better then I could. Well done 👌

[@BOb-lu3pc]

Ah well actually a new paper is supposedly coming out revalidating Troodon formosus, we actually even got to see the fossil, I unfortunately don't remember the article or where the fossil is currently held but I do know it was in the Two Medicine formation

[@aottadelsei980]

Fun Fact- the oldest definitive troodontid known is Hesperornithoides while the oldest possible troodontid was Koparion which is only known from a single tooth. Both of them are from the Morrison Formation and with a study in 2021 a suggest that troodontids evolved in North America with Geminiraptor showing the most basal characteristics of the family. Which comes from the Cedar Mountain Formation in Utah

[@darthnick427]

Can we name this one the Troodon? :') I miss them.

[@user-et6vh3wv8s]

Gigantic troodontids I thought were mainly located in colder climates like the high artic, as toodon fossils are known to be almost double to triple in size to there southern relatives in places like Alaska.

[@Im_that_archeops]

We luring archesuchus out of his house with this one

[@all_braincells_found]

holy shit the troodontids from wierd birds are real!!111!!!!11111!!11!!11111!!!!!!!!1

[@AKayani559]

Pretty sure there's no evidence that latenivenatrix is a invalid species

[@SirPigeon420]

i was confused when i heard him say latenivenatrix was invalid

[@goldman77700]

Dromaeosaurs competed against Tyrannosaurids to fill the vacuum left by Allosaurids. Assuming that's true, to me that's more interesting than a new species.

[@maozilla9149]

nice

[@matthewgordon9341]

CRAZY that all the stuff we have found so far is like not even 1 percent of the total amount that were ever alive. Meaning things could have gotten even bigger. Crazy to think about

[@brainstorm9560]

What if these giant Troodon's evolved to be more herbivorous, similar to the Therizinosaurs?

[@enfieldlammergeier]

There was a paper published on Troodontids that showed some of them were omnivores, possibly with a stronger preference for plants. So a giant Troodontid being entirely herbivorous is not off the table. New biogeochemical insights into Mesozoic terrestrial paleoecology and evidence for omnivory in troodontid dinosaurs (Cullen & Cousens, 2023)

[@joeygamingnl2724]

Nah we got real life Jurassic World Velociraptors before any news on a 4th movie

[@sethnaffziger1402]

Giant troodon is far scarier than a giant velociraptor... Troodon was likely as intelligent as popular culture and science (from 30 years ago) would have you believe velociraptors were...

[@duanenash9474]

Umm... 4.5 mph is a good clip. Even if it was moving for 6 hours a day it is then covering 27 miles a day. Thats a lot of ground getting covered.

[@DreadEnder]

*troodontid

[@evilcrashbandicootthetouho2753]

Jurassic park raptor going to be real not longer tiny In Real life

[@govardhanposina17]

The Jurassic Park Raptor was based on Deinonychus, which was still smaller.than the average human irl so no this discovery doesn't change that

[@evilcrashbandicootthetouho2753]

@govardhanposina17 in the lost world 1997 the raptor looks close to the real life size

[@davidbarkin8269]

These are very educational and I truly appreciate your work, but no offense, you talk Waaaay to fast

[@Intrusion498]

Guys remember this is an ichnogenus aka it's just a trace fossil and it's ichnogenus' name is not the name of the real animal so PLEASE DO NOT I repeat DO NOT SAY THIS IS THE LARGEST TROODONTID

[@bobthedestroyer6205]

Man please dont do the tiktok subtitles thing

[@jimbobisaballer]

Troodontids don’t exist due to the troodon not being a true dinosaur plus either way it was a dromeosaurid when it was valid
