Generally considered the oldest specimen of the lizard family Aigialosauridae, others have considered it to be a pleurosaurid, a marine sphenodontian (the order to which the extant Tuatara belongs).[2]
Proaigialosaurus was discovered in the Solnhofen limestone formation of Bavaria, Germany.[2] It was small (less than a metre long).[2]
