It's strange that these animals are never mentioned in prehistory documentaries on TV. I always took for granted that after the dinosaurs, the only big carnivorous reptiles were snakes and lizards in the shadow of mammals, then it turns out South America was still ruled by giant archosaurs right up to relatively modern times.

Dinosaurs will always be my #1, but I'd have loved to see these "panther crocs" walking around. It's always felt odd to me that fully terrestrial "crocodiles" are no longer a thing, but we have monitor lizards, kind of, copying their homework.
@Sawrattan2 жыл бұрын
I had no idea these terrestrial 'panther crocs' were even a thing, I thought it was just lizards and snakes. From what I remember, prehistory documentaries always made it clear that mammals immediately took over the world when in fact we now learn they continued to live in terror of reptiles in South America and Australia.

It's not a boring strategy you're just conditioned to view it that way because you've been seeing and hearing about them all your life. Crocodilians are loving jump scares that live their lives as horror movie monsters and they're so good at it that they've been doing it for longer than the world has had flowers

@@DragonwolfoftheSands I think you are missing my point though. I've seen crocs in the wild, they are scary creatures indeed. The boring aspect is that all species of extant crocs use essentially the same general water ambush strategy with very minor variations. Compared to their extinct relatives among which one can list pursuit predators, filter feeders, terrestrial ambush predators, open ocean predators, herbivores, digger omnivores, bipedal predators, and even arboreal predators among other things... well, I hope you can see now were I was going with my initial comment.

The more I learn about these crocodilian cousins, especially the terrestrial examples, the more they look like fantasy minor dragons to my mind. D&D calls such minor dragons "drakes" and the similarities are striking. So much so, I wonder if the creators of D&D had some knowledge of these prehistoric animals and based their dragon designs on them? Or is it perhaps just a coincidence? Hard to say but I absolutely love learning about these animals either way. It is hard to imagine seeing these guys in the wild. And yet, we have millions of years of proof that they absolutely existed. Amazing.

And yet he completely ignores the fact that terrestrial pseudosuchians were never outcompeted. The Raiusuchians were actually the dominant terrestrial animals in the Triassic, and then Crocodyliforms like Razanandrogobe went extinct only because of climate change, and not out-competition. The sebecids too were never outcompeted in South America, only going extinct because of climate change. I like tier zoo, but remember, he hasn’t ever actually shown credentials in science. Whatever he shows on his videos isn’t completely factual.

Teirzoo is not scientific nor very smart, he is very opinionated and has biases that affect his rankings. I picked up on this on his ranking of birds and realized his bias against flightless birds. The clip where he showed a domestic chicken clumsily trying to fly from the fox made me wonder if he knew that humans bred flight out of chickens yet he used it to judge chickens as a species.

Terrestrial animals' pick up scents blowing on the air currents into their faces. There's a kind of stereo effect to determine where the smells are coming from. Some animals nose around in leaf litter to pick up the smells of their food. A good example is the Kiwi which has its nostrils at the end of the bill which it pokes into sand and soil to smell its tiny prey. Nostrils on the top of the head makes it hard to do and aquatic animals are less concerned about scents.
