Omnivoropteryx (meaning "omnivorous wing") is a
Stephen Czerkas and Qiang Ji, stated that their specimen closely resembles Sapeornis, but the pubis was longer and, since no skull was known for Sapeornis, they did not consider the two names synonyms.[1] The later discovery of Sapeornis skulls shows that they were indeed similar to Omnivoropteryx. This may make Omnivoropteryx a junior synonym of Sapeornis, and the name may be abandoned.[2]
Classification
Czerkas and Ji created the
phylogenetic definition.[3]
The single species O. sinousaorum shows an interesting mix of specialized and generalized characters: the legs were short and well suited for perching on branches, while the wings were long, suggesting it did not need a running or jumping takeoff to get into the air. Its skull, on the other hand, was similar to some early
oviraptorosaurs, having the structure of a beak designed for crushing and tearing with some teeth at the tip of the upper jaw. Thus, the species may have been an opportunistic omnivore (as the name suggests), utilizing a wide range of food sources, unlike other early birds which were active predators of smaller animals.[1]
