Thalattosaur
Thalattosaurs (meaning "ocean lizards") are a group of prehistoric marine reptiles that lived during the mid-late Triassic period. Some species of thalattosaur grew to over 4 metres (13 feet) in length, including a long, flattened tail used in underwater propulsion. While they bore a superficial resemblance to lizards, the exact relationships of thalattosaurs is unknown; they are widely accepted as diapsids, but experts have variously placed them on the reptile family tree near ichthyosaurs, Archosauromorpha (archosaurs and their relatives), Lepidosauromorpha (lizards and their relatives), or as basal neodiapsids.
