Abstract

Seven new species of the genus Pediastrum Meyen, 1829 have been described from the Subathu Formation (Upper Palaeocene-Eocene), Punjab Basin, Himachal Pradesh. Significance of the morphological characters used for the delimitation of different species has been discussed with a note on the distribution of fossil Pediastrum in the Indian sediments. Comments on the palaeoecological significance of the genus have also been made which highlight its importance in different conditions of deposition.
