Two new genera of Coleoidea from the Chickasawhay Limestone (Oligocene) of Alabama

Ciampaglio, Charles N.; Weaver, Patricia G.


Two new genera, Oligorostra and Oligosella, and two new species Oligorostra alabami and Oligosella longi, of coleoids are described from the Oligocene Chickasawhay Limestone of Alabama. Oligorostra alabami is assigned to the Spirulida with uncertain family affinities. Oligosella longi is so unlike other coleoids, that at this juncture, no order or family affinities are assigned. These specimens are the first Oligocene coleoids described from North America.
