| Abstract |
Gisortia megaloptera n. sp. is described from the Ypresian, early Eocene of Gan, France. It differs from the younger G. coombii (J. DE C. SOWERBY in DIXON 1850) from the Lutetian Eocene by the structure of the posterior extremity, the stronger development of lateral flanges and protuberances, by the presence of a prominent dorsal wing, and numerous other conchological aspects. The extreme features of the holotype are backed up by several less bizarre specimens of the same provenance, which are tentatively assigned to the new species. |
