Abstract
The study further details the formation and subformation stratigraphy of the Silurian section of the northwestern Siberian Platform in terms of the distribution of ecosystems correlated to chronozones. A lithified fossil ecosystem is represented by a genetically uniform dominant lithology and the hosted fossil biocenosis, which together make an ecostratigraphic unit (lithified biocenosis or biolithocenosis). The ecostratigraphic structure of Silurian sediments in the region is described according to the ages, locations, and dominant lithologies and fossil fauna assemblages of 105 units distinguished in the section.
