Pleurosternidae is an extinct family of freshwater turtles belonging to Paracryptodira.[1] They are definitively known from the Late Jurassic to Early Cretaceous (Albian) of Western Europe and North America.[2]


Valid taxa

Uluops from the Late Jurassic of North America may also belong to Pleurosternidae.[2]

Invalid taxa


The high morphological diversity of skulls of the group suggests high ecological plasticity. Glyptops and Pleurosternon exhibit adaptions likely for suction feeding, while Dorsteochelys was likely a dietary generalist.[2]
