Bissektipelta
''Bissektipelta'' (meaning "Bissekty Formation, Bissekty shield") is a genus of ankylosaurine Thyreophora, thyreophoran dinosaurs that lived in Asia during the Late Cretaceous in what is now the Bissekty Formation of Uzbekistan. ''Bissektipelta'' is a Monotypic taxon, monospecific genus, containing only the type species ''B. archibaldi''. History of discovery In September 1998, the joint Uzbek-Russian-British-American-Project excavated the braincase of an ankylosaur. In 2002 in paleontology, 2002, Alexandr Averianov, based on this find, named a second species of the genus ''Amtosaurus'': ''Amtosaurus archibaldi''. The specific name (zoology), specific name honours James David Archibald, leading the URBAC (Uzbekistan, Russia, Britain, America, & Canada) project that performed the excavation. The holotype, ZIN PH 1/6, and only known specimen was collected from the Bissekty Formation, dating from the late Turonian-Coniacian, of Dzharakuduk. The holotype consists of a well-preserved, ...

Bissekty Formation
The Bissekty Formation (sometimes referred to as Bissekt) is a geologic formation and Lagerstätte which crops out in the Kyzyl Kum desert of Uzbekistan, and dates to the Late Cretaceous Period. Laid down in the mid to late Turonian, it is dated to about 92 to 90 Ma (million years ago). Description The lithology of the sediment largely consists of cross bedded sandstones with interbeds of massive sandstone, well cemented intraformational conglomerate, siltstones and mudstones. Most of the fossils are found as clasts within the conglomerates. Fossil content The Bissekty Formation is characterised by a mix of marine, brackish, freshwater, and terrestrial animal fossils. This stands in contrast the strictly marine fossils found in the underlying Dzheirantui Formation, and indicates that the Bissekty was formed during the regression of a saltwater sea. The coastline expanded inland again in the upper portion of the Bissekty, represented by a proportional increase of fully aqua ...
