Iniopteryx ("Nape Wing") is an extinct genus of cartilaginous fish.[1][2][3][4] It is from the Pennsylvanian epoch of the Carboniferous period, approximately 300 million years ago. Their fossils have been found in North America, primarily in two states: Ohio and Montana. In general, very little is known about this species.
Iniopteryx was a chimaera-like fish, described as "plump". It is known that the species average size was around half a meter long in length. While the species had specialized spines and fins superficially similar to that of a flying fish, there is much speculation about whether it could glide like a flying fish, or was actually benthic.
