Boverisuchus: The Prehistoric Hooved Crocodile

[@thedoruk6324]

CHimerasuchus uploads are so underrated imo. He literally shares dozens of Apex Predators that are so unique on their own. Also crocodylimorphs for the win!

[@mhdfrb9971]

CHimerasuchus and Dr. Polaris both are really underrated

[@thelaughinghyenas8465]

I agree. I really look forward to those wonderful and bizarre apex predators that nobody else details.

[@K.sstopmotion7374]

2:24 nice try but I know a skull crawler when I see one

[@patreekotime4578]

Osteoderms completely covering the tail makes me think that they helped hold their tails up more rigidly like therapods. So instead of the spines interlocking like in therapods, the ridigity came from the osteoderms. That could have aided them in bipedal locomotion and generally made them more efficient runners.

[@alexandermorrison1010]

Shame that these terrestrial crocodiles are still widely unknown to the public. Being that some of the largest forms could and did (razanandrongobe) compete against theropods. That being said this is another great addition to the collection you have made so far. Keep it up my friend.

This was really interesting. It's so freaking weird I think I will use it for a speculative evolution project. Thank you to the narrator as well.

[@adamcroft3705]

It’s almost like the archosaurs were trying to make another Mesozoic period. But the mammals had a leg up on evolution this time.

[@bkjeong4302]

More that the mammals had a head start and took over before the archosaurs really got going (though the archosaurs ended up sort of taking over again anyways in South America even with the mammals having a head start there).

[@MajinObama]

Primeval, my beloved 😭 Gone too soon! … Great video btw!

[@bkjeong4302]

The interesting thing is that Boverisuchus didn’t actually evolve due to a lack of large predatory mammals; mammals started filling megafaunal niches very shortly after the K-Pg mass extinction, and in a few million years there were mesonychids the size of lions hunting pantodonts the size of large ungulates in the Northern Hemisphere.

[@PABrewNews]

Would the terrestrial crocs have more lip like flesh around their mouths unlike their water based hiers? Just think of it due to the new debate of other land based dinosaurs. And since the artwork is generally more like a modern croc appearance. Cheers

[@SoulDelSol]

Croc teeth are on outside of their mouths so it would prob be the same?

[@chimerasuchus]

Those without aquatic ancestors, like the sebecids, almost certainty had lips. For those like Boverisuchus whose ancestors had lost them, it depends on how easy it was to revolve them.

[@PABrewNews]

@Dan they are outside because they are in the water and have no need for lips to keep them wet to negate deterioration. That's why I questioned the territorial versions.

[@patreekotime4578]

A few of the artworks do depict lips. I bet this is a subject of as much if not more debate amoung land croc researchers as therapod researchers.

Iberosuchus

[@chimerasuchus]

In addition to those mentioned in the video, Boverisuchus vorax also coexisted with the alligatoriods Procaimanoidea and Brachyuranochampsa, the latter being a survivor of the Cretaceous Period like Borealosuchus. Boverisuchus magnifrons also lived alongside the alligatoriod Hassiacosuchus and a relative of the false gharial. As a side note, although alligatoriods have been largely confined to the Americas for tens of millions of years (although the Chinese alligator migrated to Asia a few million years ago), during the Eocene they were still present in Europe and Asia.

[@Evenape]

@@chimerasuchus I thought Asiatosuchus is also a Messel crocodile? Or am I wrong?

[@Quetzalcoatl_Feathered_Serpent]

With some effort you could evolve a modern gator or croc back into a land croc. It all comes down to filling a role and perhaps putting some into a role which requires more efforts of land hunt would slowly begin the neccessary changes to adapt

Thanks a lot for creating & sharing this - highly appreciated. BTW I thought, in a cold environment, an animal that body mass having no fury integument may not even be able to hibernate, no matter how endothermic it may be, which may have been part of Boverisuchus' demise.

[@chimerasuchus]

Although cooler temperatures were likely a factor, modern alligators are able to enter a hibernation-like state.

I forget how many heart valves crocodiles have, but, I think it's like 2? 2 and half? Three? ... something that would impact its stamina for running in addition to the ectotherm thing.

[@chimerasuchus]

I think you are confusing heart chambers and valves, which are merely opening between the chambers. Although most ectothermic reptiles have only three chambers, crocodilians have four like birds and mammals. Additionally, they have a fifth heart valve, which is used to send extra blood to the stomach to aid digestion.

[@kade-qt1zu]

Quick question that is completely unrelated to the video in any way: Did Silesaurus and its relatives have air sacs? Because I heard somewhere that air sacs are ancestral to dinosaurs and their relatives. Honestly, I think you should just do an entire video on air sacs in dinosaurs.

[@chimerasuchus]

So far there is no evidence that silesaurs had air sacs. However, the same is true for ornithischian dinosaurs, so this has no real bearing on whether or not silesaurs are basal ornithischians.

[@kade-qt1zu]

@@chimerasuchus Thanks for the information. Information about the evolution of air sacs is just really confusing at times. Some sources claim that air sacs were ancestral to dinosaurs and their closest relatives, while others claim that air sacs evolved convergently multiple times. It's an absolute mess.

[@batman699]

What was the largest terrestrial predator excluding dinosaur?

[@chimerasuchus]

It was probably Faslosuchus, a Triassic pseudosuchian. The largest of the Jurassic was Razanandrongobe and the largest of the Cenozoic was Barinasuchus, both of which were also pseudosuchians. However, none of them are known from complete remains, and the last two are only known from skulls. Therefore their size estimates are based on their smaller relatives.

[@brianedwards7142]

Modern crocs kill by drowning their prey. A land living croc doesn't have that advantage.

Land crocs don't NEED that advantage to be successful

[@yallneedjesus5465]

Quick question: How did they exist on both continents of Eurasia and North America when the continents were too far apart and the land bridges can not explain it since there isn't evidence of reptilian or crocodilian Interchange from the Bering Land Bridge.

[@chimerasuchus]

North America was connected to Europe and possibly Asia by the Thulean North Atlantic Bridge. Also, although cold temperatures were a barrier to most ectotherms in the later Pleistocene, the Chinese alligator is thought to have crossed the Bering land bridge just a few million years ago. In any event, such temperatures were not a problem during Boverisuchus's time, and it may not have even been an ectotherm.

What habitat did it lived in?

Tropical forests.

Before i dive into the video: Isn't the thumbnail clickbait?? Cuz boverisuchus is clearly not hooved.....

Could a land crocodile still death roll? That's such a deadly adaptation and it still kinda looks like it could do it

With its ziphodont teeth, Boverisuchus wouldn't really need to death roll anymore. Although I know of no research relating to whether or not Boverisuchus could still do it, the vertebrae of the later land croc Mekosuchus found it had probably lost that ability.
