Abstract

In the Late Mesozoic the Eastern Urals were part of the western margin of the West Siberian basin. During the Late Cretaceous the West Siberian sedimentary basin represented a vast semi-enclosed shallow sea bounded by the Ural mountain system in the west, the uplifted Siberian platform in the east, and the Kazakh shield in the south. In the north the basin had a free communication with the Arctic ocean, while in the south-east it was connected sporadically through the Turgay trough with seas of the Tethys region and eastern marginal seas of the European boreal basin. The West Siberian Cretaceous sea and its East-Uralian water mass comprised a province of the Arctic paleobiogeographical region. Thus numerous genera and families of agglutinated foraminifera predominated in Cretaceous foraminiferal biota of the basin (Fig. 1,2).
