Species Heterohelix rajagopalani Govindan 1972

Discussion / Comments:

Van Eijden & Smit (1991):
Remarks. Intermediate forms with the unornamented H. planata (Cushman, 1938) are common. Occurring from the middle Maestrichtian upward, its local range is paleoenvironmentally controlled, as elsewhere it is known to occur in the lower Maestrichtian as well.
