Pacifichelys
Pacifichelys is an extinct genus of sea turtle from the Miocene of Peru and California. It was first named by James F. Parham and Nicholas D. Pyenson in 2010, and the type species is Pacifichelys urbinai from Peru. A second species, P. hutchisoni, was reassigned from the genus Euclastes. It is known from the Miocene of California. Like the living Ridley and Loggerhead sea turtles, Pacifichelys was durophagous, consuming hard-shelled organisms with crushing jaws.
