Abstract

The Cenomanian redbeds of southern Morocco have yielded skulls of a new genus and two new species of side-necked turtles, Galianemys whitei and Galianemys emringeri. The genus is based on a series of nine well-preserved skulls and three partial skulls. Galianemys is a pelomedusoid pleurodire belonging to the family Bothremydidae Baur, 1891, because it has: (1) precolumellar fossa absent, (2) foramen stapedio-temporale facing anteriorly, (3) eustachian tube separated from stapes by bone, and (4) exoccipital-quadrate contact. Within the Bothremydidae Galianemys is best resolved as the sister group to Cearachelys because both have the jugal retracted from the orbital margin and a small, slitlike fenestra postotica. Galianemys emringeri has a deep fossa pterygoidei, ventrally exposed prootic, foramen nervi facialis and foramen nervi vidiani, a thicker labial ridge, and the jugal not exposed on the triturating surface, while Galianemys whitei has a shallow fossa pterygoidei, covered prootic and foramen nervi facialis and vidiani, a thinner labial ridge, and a jugal exposed on the triturating surface.
