       Adocus is a genus of freshwater cryptodiran turtle that lived in both Asia and North America.‭ ‬Most Canadian and American fossils are confirmed as coming from Cretaceous deposits,‭ ‬however some fossils‭ ‬are determined‭ ‬as coming from‭ ‬deposits after the Cretaceous,‭ ‬with some as recent as the late Oligocene.‭ ‬Adocus is known to have inhabited freshwater where it is thought to have had an omnivorous diet.
