Amtosaurus (/ˌɑːmtˈsɔːrəs/; Kurzanov & Tumanova, 1978) is a genus of ornithischian dinosaur based on a fragmentary skull collected from the Upper Cretaceous Bayanshiree Svita Formation (Cenomanian-Santonian) of Mongolia and originally believed to represent an ankylosaurid. Hadrosaurid affinities have also been suggested. However, per Parish and Barrett, this specimen is too fragmentary to be reliably classified beyond an indeterminate ornithischian. A second species assigned to the genus, A. archibaldi, has become the basis of a valid ankylosaurid taxon, Bissektipelta.[1]
