摘要：
The ammonoid family Sirenitidae from the Upper Carnian yakutensis Zone of northern Middle Siberia and Northeastern Asia is revised. A new genus Orientosirenites gen. nov. with the type species O. bytschkovi sp. nov. is established based on the study of the main morphological characters of the shell. The new genus and the species O. bytschkovi are described and the species O. yakutensis (Kiparisova) is redescribed. The new data allow the taxonomic composition and the distribution of the Carnian ammonoids of the Boreal Realm to be updated.
