The Lower Carnian succession in northern Middle Siberia includes continental and marine deposits. Bivalves, nautiloids and ammonites in the marine units provide biostratigraphic control for a palynological study of three important sections. Palynomorph associations from the base of the succession include forms that have previously been reported only from Norian and Rhaetian deposits in the Tethyan and Boreal realms. This suggests that, in comparison with other areas, the palynoflora of Siberia was more uniform throughout the Late Triassic, and that the Carnian and Norian stages have a miospore assemblage that is recognizable in a wide belt through Arctic Canada and northern Eurasia.
The results of palynological study of the Synya Formation (Middle Triassic) in outcrops along the Kydz'rasyu River banks are presented. The published and archival results of previous palynological investigations of the Synya deposits were used as an additional record. It was shown that the species composition of the palynological assemblage (PA) of the Synya Formation on the Kydz'rasyu River fully corresponded to the PA Converrucosisporites conferteornatus — Florinites pseudostriatus and determined the Triassic, Ladinian, age of the enclosing deposits. The results of reconstruction of the growing vegetation testified to the existence of rich and diverse vegetation in the Ladinian Age on the studied territory, where the flora of highly moistened biotopes prevailed.
Представлены результаты изучения миосïор из местонахождения комïлекса тетраïод фауны Mastodonsaurus в разрезе надкраснокаменской свиты. Доïолнительно были ïривлечены оïубликованные ïалинологические данные ïредшествующих лет. Показано, что видовой состав ïалинокомïлекса из м естонахождения тетраïод в ïолной мере отвечает комïлексам миосïор ладинского возраста, средний триас. Палеоботанические реконструкции ïо ïалинологическим данным ïоказали на территории исследований существование растительности, характерной для условий очень теïлого и влажного климата. Кëю÷åâûå ñëîâà: споры и пыльца, надкраснокаменская свита, средний триас, Тимано�Североуральский регион.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
