摘要：
The Late Tournaisian ammonoids from the Kuilyuk Formation and the carbonate massifs of the Chatkal Group were studied in the lower reaches of the Chatkal River (Middle Tien Shan, Uzbekistan). Three successive ammonoid assemblages of the Late Tournaisian Pericyclus-Progoniatites and Fascipericyclus-Ammonellipsites Genozones were recognized. A new pericyclid genus, Parasiacyclus gen. nov., with the type species Parasiacyclus chatcalicus sp. nov., and the new species Eurites kuilukensis sp. nov., Habadraites kulosiensis sp. nov., and Nodopericyclus asiaticus sp. nov. are described. The genus Muensteroceratoides Popov, 1965, previously considered as a junior synonym of Dzhaprakoceras Popov, 1965 is reinstated and redescribed.
