Tulerpeton curtum (Lebedev 1984, Fammenian, Latest Devonian, 365 mya) was described as, “one of the first true tetrapods to have arisen.” Here it nests between late-surviving Eusauropleura and Eucritta. Very little other than the limbs are known. In life it would have been the size of Gephryostegus. Reversing reptilomorph trends, Tulerpeton lived in shallow marine waters. Metacarpal 2 is the longest. The hind limb was not so large as in predecessors. The scales of Tulerpeton were made of compact bone lacking enamel, dentine, and isopedine layers, like those found in more basal lobe fin fish.
