Batrachopus grandis: A Bipedal Crocodile Relative From the Time Of The Dinosaurs

[@denderrant]

This is so crazy. I'm still coming to terms with the Triassic land crocs being bipedal, and now we learn that one managed to happen again in the Cretaceous?? That's insane! Was Korea an island at the time? How else would something like this be able to muscle its way into a niche that therapods had perfected and dominated for so long by that point in time?

[@dralord1307]

From what I know it wasnt an island. It seems to have pretty much always been attatched to the main body of asia.

[@denderrant]

@@dralord1307 Even crazier, then!

[@rileyernst9086]

Thanks for the video. I'd also like to add to your point about sociability in modern crocs; that modern gharials are intensely social and form pretty tight groups(usually around a dominant breeding male and a group of sexually mature females, but immature gharials have been seen to join these groups including young males which were completely unrelated to the rest of the group). So even if these animals were not hunting(which lets face it, group hunting in animals gets the spotlight a lot)they might still represent a close knit group living together. Awesome work as ever. Cheers.

[@gattycroc8073]

off topic but how many of you agree that the next prehistoric documentary should take place in Cenozoic South America.

[@chimerasuchus]

It definitely deserves more attention.

[@gattycroc8073]

@@chimerasuchus especially because it was isolated and predators like the sebecids, sparassodonts, and phorisrhacids hunted the many types of meridiungulats and other herbivores. not to mention it still hand armored cubed tail herbivores, caiman relatives rivaling Deinosuchus and Sarcosuchus, and birds with wingspans rivaling some of the lagest Pterosaurs.

[@Primordial_Soup]

Ichnology is such an underappreciated field within Paleontology, there is a lot we can learn from it that we couldn't from the body fossils alone and we can get a lot of traces in places where body fossils just can't preserve for one reason or another. For anyone interested in reading further, I highly recommend "Dinosaurs Without Bones" by Anthony Martin, its easily my favorite modern book on Paleontology and its all on Ichnology!

[@janegael]

Beautifully done and fascinating as usual. I love the way all the complicated names roll off your tongue so fluently. :-)

[@MaryAnnNytowl]

You do a really good job at this. Thanks for covering the lesser known critters!

[@REVOisMYname]

That’s wild that this behaviour was present in Cretaceous and not just Triassic for crocs

[@chimerasuchus]

It may have been present in the Cenozoic as well. The terrestrial Boverisuchus might have been capable of limited bipedal locomotion, but this remains uncertain.

[@seanphelps4057]

​@@chimerasuchusI'm not sure if this is true, but I've heard that Boverisuchus' center of gravity likely prevented that.

[@posticusmaximus1739]

Maybe you could consider doing another ichnogenus episode on Prorotodactylus mirus

[@ivanvukasovic1371]

Can't wait for a dinosaur documentary in the future, and then they show upright crocodiles and go "this being is not a dinosaur, it is in fact more closely related to crocodiles". Should shock and confuse a lot of people. Crazy how nature do that indeed.

[@majidskinnerkhan6960]

Love this channel

[@davepeters4955]

Lots of weird crocs in prehistory.

[@42ZaphodB42]

Our modern crocs are the weird ones actually. These "old" crocs were warmblooded, active hunters. Our modern ones (they only exist since the late cretaceous) are the outliers, but they survived because of that.

[@HsienKoMeiLingFormerYANG]

Basically ending period of cretaceous throw callbacks from beginning triassic. Imagine a world where bipedal large crocodylomorphs hunting rhinoceros giant cousin, paraceratherium and live though up to ice age.

[@alejandroelluxray5298]

I hope the next one talks about the Purussaurus, it deserves a lot more attention

[@gattycroc8073]

any creature from Cenozoic South Amarica would make a great video.

[@denderrant]

I feel like Purussaurus deserves a bigger production. Like a half-hour special episode or something. Maybe that could be how he celebrates the channel getting to 50k or 100k subscribers or something.

[@mhdfrb9971]

Nah. It's the Fasolasuchus

You should talk about the permian marine reptile “Mesosaurus”

[@The_Cosmic_Yog-Sothoth]

Convergent evolution is a surprising effect.

[@tobybudgie]

I think it is hilarious that some batrachopus tracks were thought to be pterosaur tracks when scientists thought pterosaur tracks were made by crocodilians for so long

[@arcosprey4811]

This makes me think of an alternate timeline where crocodilomorphs became the dinosaurs. We wouldn't have gotten animals as giant as sauropods, but it wouldve been interesting to see the variation.

[@chimerasuchus]

The Late Triassic period was pretty close to that.

[@rafexrafexowski4754]

Read about rauisuchians, poposauroids, fasolasuchus, saurosuchus, prestosuchus and others, they are basically theropod-like crocodilians (not crocodilomorphs, but closely related to them).

[@mutemiz]

The Triassic was so weird

[@stefanoaccetta4231]

Grazie per l'interessante e ben spiegato video. Tale coccodrillo bipede si è estinto contemporaneamente ai dinosauri o ha resistito più tempo, così come altri coccodrilli?

[@mr.sir.]

Glad to see a Postosuchus look alike survived linking the Arkasaurs and succide

[@Bigazoa11]

is this a reupload

[@chimerasuchus]

It is a remake. It was done mostly because my original narration was really awful. The script was also rewritten and new images were used. It was pretty much the same as making a new video.

[@colb.e]

I wouldn't consider myself very educated on ichnology, and I haven't seen the research for these specimens (or any others haha). But I am curious if it could be a possibility that these animals were facultative bipeds, perhaps running through the area to make these bipedal tracks?

[@seanphelps4057]

The year is 2024, still waiting for those fossils.

[@maozilla9149]

[@AmarothEng]

I'd be careful with behavior-based speculations from tracks alone. Grizzly bears do come to the same places in fairly big numbers when the salmon time kicks in, but other than that are pretty damn solitary. Those tracks could easily be from such a moment. Saying they lived in group or even hunted in packs is a massive stretch which is of course possible, I am not saying it is not, but I'd be more careful with wording such implications as they would need far more evidence to be actually at least "likely proven". Bunch of tracks in these finds is actually not much. You can take a photo of me walking down the street next to a person I never met and then claim we are roommates based off that photo and it wouldn't be too different.

The “ch” in Batrachopus is pronounced like a K as in all related words like batrachotoxin derived from Greek βάτραχος (bátrakhos, “frog”). The number of otherwise diligent, industrious educational KZbinrs who mispronounce key words, use incorrect plural forms etc. is really surprising and somewhat regrettable. I mean, “ancestrial”? Really??
