About Eocyclotosaurus
Eocyclotosaurus (Greek 'èoos' = dawn, 'kyklos' = circle, 'ous' = ear ) is an extinct genus of mastodonsauroid temnospondyl from the Middle Triassic (Anisian). The name Eocyclotosaurus means "dawn round-eared lizard". It is characterized as a capitosauroid with a long and slender snout, closed otic fenestra, and small orbits. It measured over one metre and had a 22 cm skull.
It lived between 247 and 242 million years ago in both North America, Germany, France and the British Isles during the early Triassic.
