Abstract

The paper describes for the first time some Palaeogene plant fossils from Manipur, Northeast India. The fossils were recovered from the late Eocene and early Oligocene sediments in the vicinity of the boundary of the Disang and Barail Groups of rocks of the Imphal Valley and its adjoining areas. All the fossils belong to Angiosperms and represent monocots and dicots. The assemblage consists of mainly dicotyledonous leaves, two types of palm leaves, a fruiting shoot, a leguminous fruit and a bark. The fossil leaves show a rich morphological diversity and indicate the existence of warm and humid tropical vegetation at the time of deposition.
