Abstract

Genus Ranikothalia Caudri is described for the first time from the Upper Palaeocene sediments of Middle Andaman Island. Three species R. sidensis, R. cf. nuttalli, R. cf. tobleri along with one species of Discocyclina are described here. The occurrence of Ranikothalia has great implication in understanding the stratigraphy of the island and in deciphering the palaeogeography of the area. This point to the extension of the Ranikot Sea at least up to Middle Andaman.
