The results of biostratigraphic study of Givetian–Frasnian rocks of the Tsil’ma River basin (Middle Timan) are presented. The biostratigraphic division of the sections is based on palynological data: five palynocomplexes are distinguished in the Valsa, Tsil’ma, Ust’-Chirka, Ust’-Yarega, and Kraipol’e formations and are correlated with coeval palynocomplexes of adjacent of territories. The features of miospore associations from continental and coastal marine facies are identified. The clear cycle of origination of geological bodies corresponding to the formations is established at this territory.
