Megalancosaurus is a small diapsid reptile from the Late Triassic of Northern Italy which is closely related with Drepanosaurus and Dolabrosaurus (this latter from the Dockum Formation), forming the Drepanosauridae. The morphology of the post-orbital portion of the skull of Megalancosaurus is very bird-like in appearance, and the cervical vertebrae are very similar to the anterior cervical ones of the small specimen of Protoavis.
