Cibolaites

The genus ''Cibolaites'' is a strongly ribbed and nodose ammonoid cephalopod from the middle Cretaceous of western New Mexico, included in the taxonomic family Collignoniceratidae. A single species ''Cibolaites molenaari'' is known.
==Description==
''Cibolaites'' is a moderate-sized, somewhat involute genus, with a moderate umbilicus, that bears broad rounded ribs on the flanks which bifurcate from the umbilical shoulder on larger specimens. Whorl section is broadest though the umbilical shoulders, flanks converge moderately on a broadly rounded venter. which bears three rows of distinct, commonly elongate, nodes. (Plate 2, figs 1-9, Cobban and Hook, 1983). The suture is ammonitic but relatively simple with generally rounded, cauliform, elements. (Fig 14, p.17, Cobban and Hook, 1983). ''Cibolaites'' is similar to the Coniacian ''Barroisiceras'' which differ in having smaller umbilici and crenulate keels.
