164-Ton Fighting Pleiosaurus

This one is for Ziggy.

I'm thinking of a new kind of swimming dinosaur- a pleiosaurus hunter who could fight hard and weighs 164 tons. He even has more weapons than the super duper leopard keppard shark. His weapons are sharp teeth and sharp eyesight and powerful jaws. It can camoflauge and you don't see a thing of it. A great white shark will think it's safe to swim by this pleiosaurus because he can't see it. But then it tears that great white shark to pieces.
