Kligman et al. 2025

Eotephradactylus is an extinct genus of pterosaurs known from the Late Triassic of what is now Arizona, United States. The genus contains a single species, Eotephradactylus mcintireae, discovered in 2011 and named in 2025. It is known from part of the lower jaw, isolated teeth, and possibly a wing bone found in the Chinle Formation, which dates to the Norian age. These bones were found in a bone bed in addition to many other species, including various fish, mammal precursors, turtles, and other reptiles.
