Stephanoceras is the dominant genus of the super-family of ammanoid cephalopods, Stephanoceratoidea. They thrived during the middle Jurassic and are distinct from other ammonites for their sharper ribbing and sinuous suture lines. Stephanoceras tended to have exposed whorls, which has led to the distinct perforations in the outer rim of the interior of the shell. These specimens were discovered in the Bajocian Evercy, Normandy, France, these specimens are supplied as two polished halves, each around 50 mm in diameter and come in a white card tray with an accompanying information label.
