The term, Palaeopalynology, owes its derivation to the Greek verb Polynein-to spread, with the<br />
meaning the study <strong>of</strong> fossil pollen and spores. Spores and pollen grains are tiny bodies (30-200 µm in<br />
size) produced during the reproduction cycles <strong>of</strong> plants and possess a resistant wall, an attribute that helps<br />
these entities to be preserved in sediments. Almost uniformly distributed in air, spores and pollen settle<br />
down on the earth and ultimately reach the water bodies like pond, lake, river and seashore. In due course<br />
<strong>of</strong> time, these get preserved as fossils.<br />
The term palynology was suggested by Hyde and Williams (1944) to the study <strong>of</strong> dust. The<br />
science <strong>of</strong> Palynology deals with the spores and pollen and associated palyonodebris consisting <strong>of</strong> algal<br />
and fungal spores, diatoms, acritarchs, din<strong>of</strong>lagellate cysts, Hystrichosphaerids, silic<strong>of</strong>lagellates,<br />
coccoliths, discoasters, radiolarian and chitinozoa. This branch <strong>of</strong> study assumed importance due to the<br />
exploratory activities for coal and oil as, these studies have proved to be immensely effective in handling<br />
various problems related with age determination <strong>of</strong> strata, correlation <strong>of</strong> marine and fresh-water deposits,<br />
determination <strong>of</strong> palaeoecology and palaeoenvironment, fine biostratigraphic zonation and indication <strong>of</strong><br />
areas favourable for hydrocarbon generation.<br />
In this presentation, an attempt has been made to show how the Tertiary spore-pollen have<br />
been important in biostratigraphic and palaeoecological interpretations.<br />
