If ever we get fish/sharks I WANT THIS! It's called a Helicoprion. Yes that is a bottom jaw.

Tanky Doedicurus
Montealtosuchus Arrudacamposi or the "crocodile dog" ran really fast and had legs well more like a dog!

This beauty could run on 2 legs as well as 4. His name is Kaprosuchus saharicus. This guy would go after you with claws and teeth.

Dimetrodon is a mammal-like reptile (NOT A DINOSAUR) they were really cool and I think should be pets.

Gorgonopsia wasn't that big but was still cool, his name means 'Gorgon Face" and had one of the 1st ear bones.
Almost forgot about Arthropleura, I thought this picture was funny and yes they were that big (or bigger)
