Objective To study the morphological diversity <strong>of</strong> spores and pollen<br />
T<strong>of</strong>ind Olltpalynostratigraphic relationships between the coalbearing<br />
and associated stratafrom various sectors <strong>of</strong> this newly<br />
established coal sub-basin and 10 compare them with corresponding<br />
strata <strong>of</strong> other coal basins in India<br />
Spores and pollen recovered in the bore-hole DPD-15 have been referred to<br />
pteridophytic and gymnospermous affinities. The important genera, viz., Cyathidites,<br />
Cicatricosisporites, Osmundacidites, Alisporites, Cycadopites, Callialasporites, Podocarpidites,<br />
Clmeatisporites, Araucariacites, Laricoidites and Podosporites suggest an Early Cretaceous<br />
affinity. FUl1her work is continued.<br />

Taphonomic and cladistic analysis<br />
Collection <strong>of</strong> plant megafossils from vaJ·ious localities <strong>of</strong> the Gangapur Formation<br />
included mainly impressions and ill-preserved compressions <strong>of</strong> leaves, stem and reproduclive<br />
paris. Two distinct noral assemblages were idcntilied. Assemblage I is dominated by<br />
thc genus Elatocladus associated with Brachyphyllul11,Pagiophyllum, Allocladus, Araucarites<br />
and olher unidentified reproductive structures. Assemblage II is charactelized by Equisetites,<br />
Rhizoll7opteris, Cladophlebis, Ptilophyllul11, Pterophyllunl and other indeterminate learrossils.<br />
