Vincent and Benson, 2012

Anningasaura is an extinct genus of basal plesiosaur. It is known from a single type species, A. lymense, discovered in Early Jurassic rocks of Lyme Regis in the United Kingdom.

Discovery

Anningasaura is known only from the holotype specimen NHMUK 49202, which consists of a complete skull, palate, and mandible, with eight associated cervical vertebrae, including the atlas-axis complex. The partial skeleton came from a juvenile plesiosaur. It was originally referred to "Plesiosaurus" macrocephalus by Charles William Andrews in 1896, which is otherwise known only from the very young type specimen NHMUK OR1336. NHMUK 49202 was collected at Lyme Regis, of Dorset, from the Hettangian to early Sinemurian-aged beds of the Lower Lias Group.

Etymology

Anningasaura was first described and named by Peggy Vincent and Roger B. J. Benson in 2012 and the type species is Anningasaura lymense. The generic name honors Mary Anning, a British fossil collector who became known around the world for finds she made in the Jurassic marine fossil beds at Lyme Regis in Dorset. The specific name is derived from the name of the Lyme Regis locality where the only known specimen was collected.
