Mantelliceras is an extinct cephalopod genus belonging to the subclass Ammonoidea and family Acanthoceratidae,[2][3] that lived during the upper Albian stage up to the late Cenomanian stage of the Late Cretaceous.[1]

Description[edit]

Mantelliceras is characterized by a strongly ribbed, moderately involute shell with a moderately wide umbilicus, and rounded whorl section. The final whorl leaves inner whorls partly exposed. High standing ribs cross over the venter smoothly. Primary ribs arise from the ubilical wall. Secondaries, usually one per intervening space, arise higher on the flanks. Species of Mantelliceras are known to reach a diameter of about 13 centimeters.

Distribution[edit]

Species of Mantelliceras' have been found in Cretaceous sediments in Angola, France, Germany, Japan, Mexico, Russia, Spain, the United Kingdom and United States.[1]
