Family of extinct reptiles

Pleurosauridae, from Ancient Greek πλευρά (pleurá), meaning "rib" or "side", and σαῦρος (saûros), meaning "lizard", is an extinct family of sphenodontian reptiles, known from the Jurassic of Europe. Members of the family had long snake-like bodies with reduced limbs that were adapted for aquatic life in marine environments. It contains two genera, Palaeopleurosaurus, which is known from the Early Jurassic (Toarcian) Posidonia Shale of Germany, as well as Pleurosaurus from the Late Jurassic of Germany and France.
