Аннотация

The new zonation scheme suggested for the Ladinian Stage is based on the study of the most complete sections of northeastern Asia with a revision of the endemic boreal family Nathorstitidae. The distinguished morphogenetic succession of genera and species of this family provides the phylogenetic basis for the scheme. The early Ladinian is subdivided into the Intornites oleshkoi, Tsvetkovites constantis, and Tsvetkovites neraensis zones. Units identified in the late Ladinian are the Indigirites krugi, Nathorstites mclearni, Nathorstites mcconnelli, and Nathorstites lindstroemi zones. The Ladinian deposits of northeastern Asia are correlated with those of the Svalbard and Canada.
