Pancheloniidae is a clade of sea turtles belonging to the sea turtle superfamily Chelonioidea.[1] It is defined as all turtles more closely related to cheloniid sea turtles than to dermochelyid ("leatherback") sea turtles.[2]

Genera

The following list of non-cheloniid pancheloniid genera was published by Hirayama and Tong in 2003, unless otherwise noted.[3]
