It is proposed to introduce the following biostratigraphic subdivisions for brachiopods into the regional stratigraphic scheme of the Upper Triassic - Jurassic of East Siberian Platform and Northeast Asia: Costspiriferna asiatica (Upper Triassic, Ratian, Byrandian regiostage), layers with Piarorhynchia pomtyroli omolonensis (Sinemiurian), layers with Rudirhynchus najanensis (upper Plainsbachian), layers with Tetrarhynchia yacutica (Toarcian), layers with Gigantorhys jacuticus (Aalenian), layers with Ptilorhynchia anabarensis (Bajosian), layers with Ptilorhynchia exigua (Lower Batonian), layers with Holcorhynchia laevis (Upper Batonian), layers with Boreiothyris pelecypodaeformis (Callovian, Oxfordian), layers with Ptilorhynchia lenaensis (Kimmeridgian), layers with Fissirhynchia micropteryx (Lower Volgian), layers with Lenothyris ovalis (Upper Volgian).
