Petrified Neogene woods of Tripura

Abstract

A large number of fossil woods were collected from three new fossiliferous localities situated in the South Tripura District, India where rocks of the Tipam Group (Late Miocene) are exposed. Three of these woods, namely Bauhinia, Dipterocarpoxylon and Glutoxylon have been described out of which first two are reported for the first time from this region. Their presence indicates the existence of tropical evergreen forests in the South Tripura District during the Late Miocene.

On the evolution of Angiosperms in the Himalayan region: A summary

“…Considerable data on plant megafossils have been accumulated from the Outer Himalaya/Siwalik sediments running from west to eastern end of the Himalaya. It is the best known flora of the Himalayan region and its components are largely tropical to a few subtropical in distribution (Awasthi, 1992;Banerjee et al, 2005;Guleria et al, 2002;Joshi & Mehrotra, 2007;Mehrotra et al, 2006;Prasad, 2006Prasad, , 2007Prasad, , 2008Prasad & Pandey, 2008; for further details please refer Srivastava, 1991;Srivastava & Guleria, 2004). The recorded assemblages indicate that the area was forested by moist evergreen to semi-evergreen taxa.…”
