I’ma go with Allosaurus on account of the epic Mohawk

Ankylosaurs please. Give me an armor plated tank with a built in beat stick that could knock a midsized car several feet with a single swing.

If we are going ancient life in general I will always pick Dunkleosteus. A swimming arrangement of thick bone plates the size of a medium bus with a set of Jaws of Life (Death?) for a mouth. The damn thing could slice through or crush literally anything in the ancient oceans and shallow seas. If it weren't for the Hangenberg event Sharks and Orca would definitely be having some competition.

Ankilosaurus! I love my little tank buddy.

I've always liked ankylosaurus. It's part dino, part turtle, and part tank. If it was also a transformer it'd be the coolest thing ever.

Steakosaurus sounds good to me.

Baryonyx for sureee

Gonna have to go with Ankylosaurus, if only because Zuul Crurivastator isn't there specifically.

Ankylosaurus ftw!

I see at least one pterosaur mixed in with those dinosaurs.

Plesiosaur! It's a reptile, but neither is a mosasaur.

Seeing dinosaurs like this always makes me wonder: had they not been extinct, where would life in Earth be nowadays? Which one would have taken a similar evolutionary path as humans and start walking entirely upright? Which would have started utilising their surroundings to their advantage like humans?

Which could have turned into actual Silurians?
