Treatment

Genus Buttsoceras Ulrich & Foerste, 1936

Type species

Orthoceras View in CoL ? adamsi Butts, 1926 , from the Odenville Limestone (late Floian–early Dapingian), near Odenville, St. Clair County, Alabama, USA; by original designation.

Diagnosis

Slender orthocones with circular or subcircular cross section, and large subcentral siphuncles; siphuncular segments are tubular and composed of short, straight necks and thin, homogeneous connecting rings; a lamellar lining within the siphuncle thickens apically and either fills the siphuncle completely or leaves a narrow cavity dorsad of center that may be crossed by diaphragms; both hyposeptal and episeptal cameral deposits are known to develop (adopted from Hook & Flower 1977).
