Protorothyris is an extinct genus of Early Permian protorothyridid known from Texas and West Virginia of the United States . It was first named by Llewellyn Ivor Price in 1937 and the type species is Protorothyris archeri. P. archeri is known from the holotype MCZ 1532, a three-dimensionally preserved skull and from the referred specimens, which come from four additional individuals, MCZ 2147-2150. All specimens were collected in the Cottonwood Creek site, from the Archer City Formation, Texas , dating to the Asselian stage of the Cisuralian epoch, about 299–294.6 million years ago.[1] A second species, P. morani, was first named by Alfred Sherwood Romer in 1952 with its own generic name, Melanothyris.[2] In 1973, J. Clark and Robert L. Carroll recombined P. morani as a Protorothyris species. It is known from the holotype CM 8617, a three-dimensionally preserved skull. It was collected in the Blacksville site, from the Washington Formation (Asselian stage) of West Virginia.[3] Protorothyris was the size of the average lizard, about 30 cm in length.[4]
