Quitmaniceras is a genus of small, compressed, fairly evolute ammonites from the lower Turonian of Grant County, New Mexico and Trans-Pecos Texas, included in the subfamily Acanthoceratinae. The shell has a carinate venter in juveniles and one that is arched in adults, usually with a raised siphonal line,(siphonal referring to the marginal siphuncle). Ribs are very weak to moderately strong, flexious, typically sloping forward toward the rim, bending further forward at the outer shoulder.
Distribution
Fossils of Quitmaniceras have been found in Colombia (Loma Gorda Formation, Aipe, Huila),Patarroyo, 2011, p.69 Mexico and the United States (Arizona and Texas).[https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=15215 Quitmaniceras] at Fossilworks.org
