I really appreciate having a paleo channel that gives long overdue attention to Pseudosuchia. I've learned so much and I find it incredible that before seeing your (original upload) video on _Barinasuchus,_ I had no idea 6 meter, 1500kg crocodile cousins stalked the _Llanos_ and _Cerrado_ into the middle of the Miocene. I can't understand why not one other paleo channel (except Dr Polaris) or documentary I have watched in the last thirty years has found that worth mentioning.

In theory they would be the next best group to study outside of Therapoda themselves

The ‘teeth drying out’ argument isn’t really valid anymore and has been disproven by the West African crocodile, which can spend months hibernating in dry burrows, no where near a source of water, and their teeth are completely fine. I think restoring Sebecids with lips is a bit ridiculous. I mean most theropods probably didn’t have lips anyway. The whole lipped theropod idea comes from paloeart trends rather than actual fossil evidence

@chir0pter2 жыл бұрын
The history of land predators in Cenozoic South America is a strange one. For one, the fact that there were no real large land mammal predators until the hyperspecialized Thylacosmilus (deserves its own video) in the late Miocene, and even that wasn't much bigger than a large wolf or leopard; and it apparently went extinct in the Pliocene, supposedly long before large carnivorans made it to SA in the Pleistocene (but after the Great Interchange began). So why did it go extinct? Could be global cooling, or perhaps the first smaller carnivorans to arrive in the Pliocene ~5mya introduced some novel disease like distemper or scabies, or a combo? Why didn't it evolve larger? Some life-history feature of metatherians that prevent them from becoming larger carnivores, perhaps if they were relatively precocial & had to survive independently early? Competition from phorusrhacids/sebecids? Didn't stop large mammalian carnivores from evolving elsewhere... Secondly, the question of what happened to the Sebecids is probably due to global climate change, not local; the Andes had been high mountains for many 10s of millions of years, and we know globally climate sharply deteriorated after 13-10 mya (e.g. 10.1038/ngeo2813, other papers). The fact though that Purussaurus persisted into the latest Miocene is possibly because all the appropriate lowland sebecid habitat in the warm tropics was essentially swamp by the end Miocene, and prowled by Purussaurus. Or we just don't have the fossils of remnant Sebecidae. Finally, what role did the terror birds play in structuring animal communities? Did they actually tackle large prey, perhaps by attrition wounding? Or stick to prey smaller than themselves, like flying accipiters generally do? Did the largest SA mammals have any predators at all from birth to death, outside of the Amazon swamps, after the sebecids? Phorusrhacids too went extinct by end-Pliocene, despite being perhaps the only remaining large predators in SA. Especially by the Pliocene, and definitely by the Pleistocene if we believe large carnivorans didn't arrive until ~1mya, there seems to be a total absence of large predators in SA for at least a million years.
@chimerasuchus2 жыл бұрын
I would like to add that members of a sparassodont clade called Proborhyaenidae grew much larger than Thylacosmilus. Estimates of their size are as high as 150 kilograms, the same as a large female black bear. They also lived before the sebecids died out. While able to compete and perhaps outclass the likes Sebecus, or Langstonia they still had no chance of scaring off a species like Barinasuchus.

Fantastic vid as always. Question for you: Do you think that Sebecidae really was taxonomically limited to just those large forms by the end of their lineage? What I mean is, that could just be the impression that preservation bias is giving us. Large animals preserve better than small ones, and SA's fossil record is only recently becoming as deeply explored as northern continents, with a great many discoveries yet to come, I'd wager. I don't see any reason why there couldn't have been smaller sebecids running around filling mesopredator niches. To borrow an example from your video, while some of Australia's top predator roles were filled by Megalania and Komodo dragons, perenties were still a thing.

It seems that only smaller species survived, assuming there even were any large ones during the Mesozoic. Also, the sebecids were ectothermic, is not to the same degree as crocodilians. Also, plenty of other clades that survived past the end of the Cretaceous Period, such as the choristoderans, multituberculates, and the dyrosaurids (another clade of crocodylomorphs), also died out between the 66 million years between then and now. The reasons the sebecids went extinct were discussed in the video.

This is going to be an unpopular opinion BUT the sebecids remind me more of the pseudosuchians that became the dominate land animals in the Triassic more than they do of true dinosaurs. There is strong evidence that Dinos were indeed warm blood, their posture, much like land mammals today was upright rather than the default sprawling gait we see in modern reptiles, dinos had the ability to produce feathers, lacked osteoderms (with some VERY notable exceptions, hello ankylosaurs!) their growth rates were little short of explosive and seemed to have developed a work-around to the turbinate bones endothermic animals need for heat regulation. It irks me when people lump in the pterosaurs and dinosaurs with modern day reptiles like lizards and tend to think of dinosaurs/pterosaurs as some form of jumped-up Komodo Dragon or Nile crocodile rather than what it truly was. I believe a better comparison to non-avian dinosaurs (in looks, appearance and behavior) are modern flightless birds such as emus, rheas, ostriches, the Red-legged Seriema, the terror birds of centuries long pass ( the Phorusrhacos) and the Cassowary. LIFE is precious, which is why I dabble in Paleontology and, in my opinion, past organisms were better adapted that what we give them credit for. More often than not, entire groups of animals became extinct not because something "better" came along but because of either a major catastrophe or the climate shifting bit and the rules for life on Earth changed. However, I'm an amateur, so feel free to correct me......

It would only take for the planet to warm up just as it did in the creatacous and these guys could've became something truly terrifying. Something equal to the theropod dinosaurs or surpass them

An informative video! A few constructive criticisms: 1. Especially, not "expecially" 2. The ending "dae" is pronounced "dee" not "day". Other than that, cool information. Thanks for sharing!

Australia was pretty weird as well. It was home to numerous strange marsupials, lands crocs such as Quinkana, gigantic monitor lizards like megalania, and even the terror bird-like dromornithids (although they may have been herbivores).
