This paper deals with an occurrence of the genus Paratorotalia (foraminifera) recorded in the Adanakurchchi limestone beds of Niniyur Formation of the south Indian, Cauvery Basin. The genus is present abundantly in the limestone beds from Adanakurhchchi area. The fossil has been described from SEM microphotograph and from a comparison with other known genera like Pararotalia tuberculifera, the present form is shown to be a new member of the genus Pararotalia. This new form has been named Pararotalia niniyurensis n. sp., The occurrence of Pararotalia in association with Thalmannita in calcareous limestone in Niniyur Formation indicates Palaeocene age to the Niniyur Formation.
