Jolietoceras


''Jolietoceras'' is a compressed, annulate, lituiconic nautiloid included in the derived Tarphycerid family, Uranoceratidae. The shell is gyroconic in the early stage, becoming straight and more rapidly expanded in the later. sutures are straight and transverse. Surface annuli slope strongly to the rear, dorso-ventrally, in the early gyroconic stage but a lacking in the later straight segment.
''Jolietoceras'' comes from the Middle Silurian of the United States (Illinois, Wisconsin).
The Uranoceratidae, ''including Jolietoceras'', were one included in the Barrandeocerida (Sweet, 1964), which has since been incorporated into the Tarphycerida.
