Neusticosaurus edwardsii

Neusticosaurus (sometimes misspelled Neuticosaurus) ("swimming lizard"), is an extinct genus of marine reptile belonging to the pachypleurosaurs, from Italy, Switzerland and Germany. Neusticosaurus was one of the smallest nothosaurs and probably fed on small fish. The type specimen is held at the Natural History Museum UK (NHMUK PV R53).
