摘要：
Subsurface sediments from a well in Ramnad sub-basin have revealed the presence of the foraminiferal genus Orbitoides from the Upper Cretaceous sequence. Detailed morphometric analyses of these specimens have confirmed the record of Orbitoides tissoti (Schlumberger), a species known from the stratotype Campanian exposed at Aubeterre - Sur Dronne section, France. This is the first record of the genus Orbitoides from Cauvery Basin as well as from the Indian region. The chronostratigraphic value of the species of Orbitoides in the Upper Cretaceous biostratigraphy has been stressed.
