ⓘ Pleurosaurus

Pleurosaurus is an extinct genus of diapsid reptiles belonging to the group Sphenodontia, extinct relatives of the modern tuatara. Pleurosaurus fossils were discovered in the Solnhofen limestone formation of Bavaria, Germany and Canjuers, France. It contains two species, P. goldfussi and P. ginsburgi.

Pleurosaurus is one of the few known aquatic sphenodontians. His body was about 1.5 m 4.9 ft long, and extra long for hydrodynamic streamlining, relatively short limbs and powerful tail. He would quickly swim by undulating slender body in a snake like fashion. It was just a small limb that is not likely to help in swimming, and nostrils placed far back on the head, close to the eyes.
