Maybe Rauisuchians died out at the end of the Triassic b/c the dicynodonts they preyed on tied out at the same time. The problem with being an apex predator is you need a lot of food to keep your super strong predator body going. Whereas the early dinosaurs were still (relatively) small & unspecialized at that point in time.

I think Rauisuchians didn't survived because they were large specialized terrestrial predators hunting midsized animals. When the habitats were deeply disturbed, their prey vanished, top predators gone extinct with them. Meanwhile, early dinosaurians were able to survive hunting insects, little game, and some of them also feed on seeds and plants. Crocodilians relied on their metabolism and quickly replenished supply of amphibians and fish. Our pre-mammalian ancestors probably took advantage of their ability to scavenge and hunt insects at night, and life went on with this new setting. This scenario happened again 150 Mya after that during the Cretaceous extinction and the ability to feed on insects and seeds using their beaks explain why only the avian dinosaurs survived.

After watching the view about Thylacoleo, I find it fascinating that the all of these families end up producing a creature with very similar traits to that of a present day tiger. Quadruped that’s an ambush predator and one of the top predators. I wonder why it’s more advantageous to be bipedal though. You look at all the big time carnivores, I believe mostly in the Jurassic to Cretaceous like T-Rex, and Allosaurus. What does being bipedal grant you? The only things I can thing of is more powerful legs, which may allows you to be quicker(not sure though because those two legs are doing the work of 4). The second thing is that it would make them taller and maybe allow them to scare away other apex predators.

If *some* therapods were quadrupedal, that is. Postosuchus at least seems to have made the transition to bipedal. Whereas therapods made that transition to bipedalism before they got big, rauisuchians got big first and were only starting to diversify in that manner when a mass extinction hit. Sometimes convergent evolution takes different paths to reach a similar result.
