Abstract

Various species of hilate spore genera, viz., Coptospora, Aquitriradites, and Cooksonites from the subsurface Sriperumbudur beds of the Palar Basin have been described. Aequitriradites spinulosus and A. verrucosus are the more commonly encountered taxa. The occurrence of hilate spores and their association with a number of characteristic Lower Cretaceous sporomorphs is indicative of a Lower Cretaceous (Neocomian-Aptian) age for these beds.
