Unguinychus

Genus of drepanosaurid reptiles

Unguinychus is an extinct genus of drepanosaurid reptiles from the Late Triassic Garita Creek Formation of New Mexico, United States. The genus contains a single species, U. onyx, known from several partial claws. In contrast to some of its relatives that may have been arboreal, Unguinychus may have been a more fossorial species. Based on the morphology of the claws, Unguinychus appears to be most similar to Skybalonyx, another possibly fossorial drepanosaur from the Chinle Formation of Arizona.
