Abstract

Palynological study of Mesozoic sediments (Late Triassic to Late Jurassic/Early Cretaceous) from a bore-hole RJR-2 drilled near Kazigaon Village in Rajmahal Basin has been done and 76 genera and 132 species have been recognised. Of them, one genus and 13 species are new. A check-list along with descriptions of new proposals have been given. The distribution of various species in Rajmahal and Dubrajpur formations is distinct. Palynological succession denotes three identifiable associations of the Late Carnian, Early Norian and Late Jurassic/ Early Cretaceous age.
