Rhamphinion was a pterosaur from the Early Jurassic period. Only tooth pieces, the posterior portion of the skull, and a wing metacarpal from this flying lizard have been discovered in Arizona’s Kayenta Formation. A accurate classification is difficult due to the scarcity of fossil material.
The skull of Rhamphinion is known from four bone fragments: one from the occipital area, one from the left cheek, one from the jaws, and one that cannot be identified. The cheek bones reveal the bottom margins of the huge antorbital fenestra and orbit. The jaw part contains two teeth. It consists of recurved cones with longitudinal ridges.
