Abstract

The palynofloral assemblage from the sediments of Barail Group exposed on the Moriani-Mokokchung Road, Nagaland contains 43 genera and 52 species. Spores of Parkeriaceae and Polypodiaceae dominate the assemblage, whereas Tricolporopilites, Lanagiopollis, Lakiapollis and palm pollen are the major angiospermic elements. The assemblage compares well with that of the Kopili Formation of Assam and Bengal Basin and Harudi Formation of Kutch Basin. The palynoassemblage indicates an Upper Eocene age. The presence of Barringtonia and Parkeriaceae indicates swampy environment of deposition.
