The paper gives palynological and micropaleontological characteristics of Kazantsevian marine deposits of the Arctic zone of West Siberia. Landscapes and climate, microfossil (foraminifer) communities on Severo-Kharaelakhskaya 50 log located in the vicinity of Lake Pyasino are estimated. It is shown that at the Kazantsevian time there was northern-taiga vegetation where the present-day cold desert (tundra) is. The size of landscape boundary migration is established. Average annual temperature in different parts of the plain varied between 2.5-4.5°C on the western bank of the Yamal peninsula and 5-6°C on the Yenisei River near Lake Pyasino.

Key words: late neopleistocene, Kazantsevian interglacial period, vegetation, foraminifer associations, frozen soil, average annual temperature.
