Gleviceras

Gleviceras produced laterally compressed involute shells with a small umbilicus, close spaced sinuous ribbing, and a sharp keel along venter. The suture is ammonitic with deep narrow complex lobes. It is similar to Oxynoticeras except for being less narrow and having a more rounded venter. Fastigiceras differs primarily in having an occluded umbilicus.

Gleviceras was described by Buckman in 1918 and is included in the Family Oxynoticeratidae and superfamily Psiloceratoidea. Species include:

• Gleviceras doris Reynes, 1879
• Gleviceras guibalianum D'orbigny, 1844
• Gleviceras iridescens Tutcher and Trueman, 1925
• Gleviceras lotharingius Reynes, 1879
• Gleviceras palomense Erben, 1956

Gleviceras is closely related to the genera Cheltonia, Hypoxynoticeras, Oxynoticeras, Paracymbites, Paroxynoticeras, Radstockiceras and Slatterites.
