Ymeria denticulata
Ymeria denticulataYmeria denticulata was an early predatory stem tetrapod that navigated the tropical freshwater wetlands and river deltas of Late Devonian Greenland. Possessing a compact skull roughly ten centimeters long armed with sharp marginal teeth, it stalked fish and soft-bodied invertebrates among shallow submerged vegetation. Close structural similarities to Ichthyostega indicate it possessed a sturdy postcranial skeleton and primitive limbs tailored for sprawling movement in swampy shallows.
