A total of four rudist taxa had been distinguished from the Sangzugang Formation and the Langshan Formation of the Lhasa block, Tibet by Rao et al. [4, 5]. They are Auroradiolites biconvexus [5], Magallanesia rutogensis [5], Eoradiolites cf. hedini and Sellaea sp. The genus Auroradiolites was established for a group of SW Asian to the Pacific endemic radiolitids that featured by an entirely compact outer shell layer. The geological range of this rudist assemblage is Late Aptian to Albian. The mid-Cretaceous SW Asian-Pacific province was recognized based on the occurrence of endemic rudist taxa Auroradiolites and the accompanying polyconitid lineage, Horiopleura haydeni—Praecaprotina—Magallanesia.
