Abstract

A detailed study of dinoflagellate cysts belonging to Alterbidinium Lentin & Williams 1985, recovered from Trichinopoly Formation (Turonian-Santonian), Cauvery Basin, southern India, revealed new information that the 2a intercalary periarchaeopyle and endoarchaeopyle are dissimilar in shape represented by steno- iso-deltaform and eury-deltaform respectivelv. The genus Alterbidinium and its two species, viz., A acutulum (Wilson) Lentin & Williams 1985 and A. minus (Alberti) Lentin & Williams 1985, are emended and a new species, A papilllatum is proposed.
