Bissektipelta archibaldi (Parrish & Barrett, 2004) > Amtosaurus archibaldi (Averianov, 2002)
Based on an ankylosaurid braincase
Parrish, Jolyon & Paul Barrett, 2004. A reappraisal of the ornithischian dinosaur Amtosaurus magnus (Kurzanov and Tumanova 1978), with comments on the status of Amtosaurus archibaldi (Averianov, 2002). Canadian Journal of Earth Sciences 41 (3): 299-306.
Abstract: A fragmentary braincase from the Baynshirenskaya Svita (Cenomanian–Turonian) of Amtgay, Omnogov, People\\\\\\\'s Republic of Mongolia was described as the holotype specimen of the ankylosaurid dinosaur, Amtosaurus magnus (Kurzanov and Tumanova, 1978).
However, the validity of this genus has been questioned by several authors. Recently, a second species, based on a fragmentary specimen consisting of a braincase and partial skull roof, was assigned to Amtosaurus as Amtosaurus archibaldi (Averianov, 2002).
Here we re-assess the status of Amtosaurus and of the referred species, A. archibaldi. We conclude that Amtosaurus magnus is a nomen dubium that should be regarded as Ornithischia indeterminate. However, Amtosaurus archibaldi is a valid taxon, characterized by an autapomorphic feature of the skull roof, and we refer this species to the new genus Bissektipelta.
