In Kerala Basin the Tertiary sedimentary sequence is represented by Quilon and Warkalli formations. Palaeoassociations of upland, lowland, fresh-water, sandy beach and mangrove vegetations have been figured out. Composition of the palynological assemblages indicates the existence of tropical rain forests with a high degree of rainfall. Dinoflagellate cysts and pollen grains of Barringtonia, Rhizophora, Nypa and Calamus suggest deposition under brackish water mangrove swamps. The sandy beach conditions are indicated by Palmidites, Palmaepollenites and Quilonipollenites. Divergent views on the age of Quilon and Warkalli formations have been reconsidered on the basis of new palynological evidences.
