In any one locality, you'd find 50 or 60 different species of reptiles living side by side
specialized on different diets, different habitats and so on.
This is the skull of dicynodon.
It's sitting with the top of the skull, just here coming down to the snout.
This is a tortoise-like beak that sits under here.
Dicynodon was a hippo-sized plant eater.
Filled the niche of the cow in a modern day pasture except these would live in herds and roam around the Permian flood plains.
Its principle predator was dinogorgon, the king of the Permian jungle.
These were real terrors. The first time the world had ever seen such top carnivores as they're called.
They had sabre teeth this sort of length, and just like the famous sabre tooth cats of much later.
They would leap on the backs of these hippopotamus-sized plant, just piercing through their thick skin tearing the flesh.
