Gobisaurus by Moondawg

Gobisaurus is an ankylosaur from the Upper Cretaceous Ulansuhai Formation (Nei Mongol Zizhiqu) of China.

The holotype consists of a skull and as yet undescribed postcranial remains. Along with its sister taxon Shamosaurus, Gobisaurus is "nested deep within the ankylosaurid lineage as the first successive outgroup to (the subfamily) Ankylosaurinae" (Vickaryous et. al., 2004). This is a large ankylosaur, with a skull measuring 46 cm. in length and 45 cm. across. The name means "Gobi (Desert) lizard," referring to its discovery by the Sino-Soviet Expeditions (1959–1960) in the Gobi Desert of Mongolia. The genus is monotypic, containing only G. domoculus.
