Abstract
Three subdivisions of Siwalik, vi/ , Lower, Middle and Upper are exposed m reverse stratigraphtc order in the Kameng District of Arunachal Pradesh. A rich assemblage of plant fossils is present in the Siwalik Group of rocks. The megaplant remains including one leaf compression and cuticular fragment from the Upper Siwalik of the West Kameng District have been described. The leaf compression shows its affinities with Termmaha catappa of Combretaceae whereas the cuticular fragment is assignable to Pihpancittis Roselt and Schneider and has been described as a new species named P arunachalensis sp nov. The presence of T calappcns very significant as it points to coastal depositional environment.
