Pacifichelys is a genus of sea turtle that lived along the coastlines of Peru and California during the mid Miocene. The morphology of the skull suggests that Pacifichelys fed upon hard shelled organisms such as shelled molluscs and crustaceans. A former species of Euclastes, E. hutchisoni, has now been renamed as a species of Pacifichelys.
