Abstract

Present article reports a dinoflagellate assemblage from Vriddhachalam area, Cauvery basin, South India. It includes 13 genera with 14 recognizable species and a single acritarch genus Pterospermopsis. The dominant constituents of the assemblage are: Cordosphaeridium, Cyclonephelium, Areoligera, Spiniferites and Dinogymnium with less common occurrence of Apteodinium, Lanternosphaeridium, Diphyes and Ceratiopsis. The age of the assemblage has been concluded to be uppermost Maestrichtian, may be representing Maestrichtian-Danian transition.
