The Callovian to Volgian section in the Tyumenskaya superdeep well SDW-6 is very important for the development and improvement of Jurassic biostratigraphy in West Siberia. It was drilled with almost continuous recovery of core (about 200 m), which is characterized by rich assemblages of microfossils. In this paper the results of micropalaeontological and palynological studies of the most complete Jurassic succession in the north of West Siberia are discussed, taking into consideration the problems of bio- and lithostratigraphy of the region
