Eleven veneroid (Bivalvia) species are systematically described from the Campanian-Maastrichtian (Late Cretaceous) sediments of Ariyalur sub-basin of South India. Among these, only Crassatella (Crassatella) macrodonta (Sowerby) and Arcticalacianata (Stoliczka) were earlier recorded by Stoliczka. Protocardia (Pachycardium) madagascariensis (Colignon), Protocardia (Pachycardium) pauli (Cocquand), Epicyprina angulata (Sowerby), Venilicardia truncata (Sowerby), and Calva (Egelicalva) buttensis (Anderson) were previously unknown from the Late Cretaceous horizons of the Indian sub-continent. The present record also includes a new species Palaeomoera stoliczkai n. sp. erected on the basis of its unique hinge characters and surface features. Lucina (Lucina) cf. fallax Forbes, Nicaniella (Nicaniella) aff. trigonoides (Stoliczka), and Corbicula? sp. indet., are tentatively identified because of their imperfect preservation. The present record may add useful information to the understanding of the Late Cretaceous palaeobiology of the region.
