Description
This beautifully preserved Mantelliceras ammonite fossil is an authentic marine cephalopod from the Cretaceous period, originating from Morocco. With a shell diameter of approximately 5 inches, it showcases the iconic ribbed morphology and coiled structure characteristic of the genus.
Mantelliceras is a genus of ammonite within the family Acanthoceratidae, commonly found in Cretaceous marine strata of North Africa and Europe. These ammonites are noted for their strong ribbing, involute shell, and typically compressed whorls.
This fossil dates to the Late Albian to Early Cenomanian stages of the Upper Cretaceous, around 100 to 95 million years ago, and was formed in an epicontinental seaway environment that once covered parts of what is now Morocco.
