Triassic Gastropods of the Southern Qinling Mountains, China

Abstract

Forty-eight species in 27 genera of gastropods, including 14 new species and one new genus, are described from early- to middle-Triassic (Scythian- to Ladinian-aged) rocks from the southern Qinling Mountains of Gansu and Sichuan provinces, China. This report expands the knowledge of the biogeographic distribution of gastropods during the recovery from the end-Permian mass extinction. The new taxa include Tongweispira sichuanensis, new genus and new species, and the following new species: Ananias guojiashanensis, Worthenia extendia, Gosseletina? dangchangensis, Zygites laevigatus, Trochotoma (Discotoma) gansuensis, Cheilotomona acutocarinata, Naticopsis (Dicosmos) compressus, Naticopsis (Discosmos) sichuanensis, Naticopsis? ribletella, Neritopsis planoplicatus, Platychilina sinensis, Platychilina obliqua, and Omphaloptycha gansuensis.
