"Bissektipelta" (Averianov, 2002) is an ankylosaurid dinosaur from the Upper Cretaceous of Uzbekistan. The holotype (ZIN PH 1/6) and only known specimen was collected from the Bissekty Formation (lateTuronian-Coniacian), of Dzharakuduk, and the name "Bissektipelta" refers to this geological formation ("Bissekt" + Greek "pelte" = "shield"). The holotype consists of a braincase and incomplete skull roof, along with isolated teeth and osteoderms. Originally, this material was referred to the genus "Amtosaurus"," but was reassigned to a new taxon when that genus was declared a "nomen dubium". "Bissektipelta" is presently monospecific, containing only "B. archibaldi". The holotype was collected in September of 1998 by the joint Usbek-Russian-British-American-Project. This specimen can be distinguished from "A. magnus" in having three exits for "N. hypoglossus" (XII) instead of two, by the lesser angle between ventral surfaces of basisoccipital and basisphenoid, and by the more caudally situated basispterygoid processes.
