Abstract
New data are reported to give stratigraphic support for the age of Paleogene marine and Paleogene-Neogene continental deposits exposed in three wells drilled on the Irtysh River near the town of Omsk, West Siberia. According to dinoflagellates and SPA, two formations, Lyulinvor and Tavda, have been recognized as part of the marine Paleogene. On the basis of dinocysts, two zones are established in the Lyulinvor Formation, named after the index species: Dracodinium varielongitudum
