 It was a small, lizard-like animal, about long, with numerous sharp teeth indicating an insectivorous diet.Other examples include "Westlothiana" (for the moment considered a reptiliomorph rather than a true amniote) and "Paleothyris", both of similar build and presumably similar habit.The earliest amniotes, including stem-reptiles (those amniotes closer to modern reptiles than to mammals), were largely overshadowed by larger stem-tetrapods, such as "Cochleosaurus", and remained a small, inconspicuous part of the fauna until the Carboniferous Rainforest Collapse.
