Sauropteryiga is the Superorder of Marine Reptiles that dominated in the Mesozoic era. "Sauropteryiga" literally means "Lizard Fin" in Latin. They are characterized by a configuration in structure in their shoulder, which supports flippers for propulsion and swimming rather than limbs.

These long-necked forms undoubtedly fed on fish, which they probably snared in their tooth-lined jaws with rapid lunges of the neck and head.
