Gobi Reptile Fossil SkullDescription: This is the well-preserved skull of a lizard from the famous Bayan Mandahu location in the Gobi which was initially named Macrocephalosaurus by Charles Gilmore in 1943. Gilmore was a member of the famous Central Asiatic Expeditions to the gobi led by Roy Chapman Andrews in the 1920's. The family was named the Macrocephalosauridae (large headed), but this name was subsequently found to be preoccupied. As a consequence, the Family was renamed Gilmoretiidae, and the genus Gilmoreteius by Langer in 1998 so as to honor the efforts of Gilmore who carried out an extensive study of fossil lizards from the Gobi.
