Scutosaurus

Scutosaurus is an armoured pareiasaur from the premain period, and is loosely related to turtles. these animals were prey to Gorgonopsid, none came through an anomaly that the ARC is knows of.

it has a stocky build and is much larger then it is in real life. When Markus got sent into premain anomaly he saw a large herd of these animals and estimated that there were 500-700 animals in total
