Pacifichelys is an extinct genus of sea turtle from the Middle Miocene of Peru ( Pisco Formation ) and California ( Temblor Formation ). [1] [2] It was first named by James F. Parham and Nicholas D. Pyenson in 2010, and the type species is Pacifichelys urbinai from Peru. [2] 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. [2]
