gerrothorax

probably what happens when evolution driven a steam roller for a bit and ended up running over a temnospondyl amphibian by accident. gerrothorax was a 3 foot long amphibian that lived in the Triassic. it had wide jaws filled with frighteningly pointed teeth. it's eyes are located above the head, suggesting that gerrothorax was an aquatic ambush hunter. waiting patiently while being camouflaged in the murky ground before targeting, lunging, and swallowing an unfortunate fish or other amphibian.
