What is "sinonyx"

Sinonyx ("Chinese Claw") was a wolf-like ungulate Mesonychid mammal from the late Paleocene of China that lived about 56 million years ago. It was an early primitive form of mesonychid, which some experts regard as a distinctive group of carnivorous condylarths, which gave rise to artiodactyls. Sinonyx was discovered in the Anhui province, China (, paleocoordinates ).
