| TITLE: | Late Cretaceous sea turtles from the Chico Formation of California

| | ABSTRACT: | New chelonioid sea turtle specimens from the Late Cretaceous (Campanian) Chico Formation of Northern California include taxa from the clades Cheloniidae and Dermochelyidae. The dermochelyid material represents at least one undescribed species. These specimens are the oldest Pacific occurrence of cheloniids and dermochelyids, and one of the oldest records of their association. No protostegids are known from the Chico Formation, highlighting the taxonomic differences between the pre and post-Campanian Pacific Ocean turtle faunas. The turtles of the Chico Formation exhibit bioueographic affinities with both Japanese and Eastern North American Late Cretaceous chelonioids.
