comparison with Gondwana, Cathaysiall and Allgaran elements
to trace their origin
Several good specimens orthe genus Kall'a~ioph)'I//IIn coli eelcd Ii'omthe DunpaUlri
Member of Mama! Formation were sorted, cleaned and photographed. It has been observed
that not a single leafis preserved in a flat position, almost all arc folded. The leaves bave an
incipient parallel venation. Cellulose acelale pulls were made from these specimens for the
recovery of cuticles. No cuticle was recovered but the macerate did contain a few monosaccate,
disaccate-nonstriate and disaccate-slriale pollen. These pollen are identifiable up 10generic
level. The genera that have been identified include Cordaililla, POlonieisporites,
IJensipolleniles, Slriomollosacciles, Schellrillgipolleniles, Cedripiles, Prolohaplo~ypilllls,
Slrialiles, Lahiriles, Gondwanipol/elliles, Rhizomaspora and Schizopol/is.
On the basis of composilion of the megaflora, the Mamal Formation has generally
been equated WiUlthe Karharbari 'Formalion' of Gondwana Supergroup of the peninsula.
The composilion of palynoflora from the I)unpatbri Member, particularly the presence of
the genus Schi~opol/is suggests that this member may be equivalenl of the basal part of the
Barakar Formalion. Except for the presence of Ulegenus Cordailina, the palynoflora known
so far is Iypically Gondwanan in composition.

palynoassemblages of peninsular India and establishes correlation between the palynoassemblages
from marine and continental sequences at Permian-Triassic transiLion.
