Species Pectunculus paytensis d'Orbigny 1842

Discussion / Comments:
Griffin & Nielsen (2008):
TYPE MATERIAL. There are four syntypes in the Typothèque of the Laboratoire de Paléontologie in the MNHN in Paris, under number MNHN-A13913. REMARKS. All four syntypes are small, badly decorticated shells in which the ligament area can be seen. The ornamentation is largely missing, but what is left suggests very weak flat radial ribs. There is no articulated pair to match d’Orbigny’s plate 15, figure 13, but it is clear that figures 11 and 12 are based on the largest two of the syntypes. The name Pectunculus paytensis apparently has been overlooked in all subsequent works, as it does not even appear in synonymy lists.
