Abstract

The paper deals with the plant fossils of Dubrajpur Formation exposed at Khatangi Hill in the Rajmahal Basin, Bihar. The assemblage is dominated by cycadophytes, though pteridophytes are quite frequent. Conifers are poorly represented. The genera Onychiopsis, Ctenis, Taeniopteris and Pagiophyllum are recovered for the first time. In view of the present finding, the age of the Khatangi sediments is discussed. The dominance of cycadophytes and poor representation of conifers indicates subtropical to tropical climate prevailing at that time.
