Description
ammonite, cm 8,2, 270 gr, only a piece.
This form was one of the most typical of the Upper Cretaceous ammonites, with an unusually thick shell with rich ornaments. The section of the shell was vaguely square and the last lap was not very high. The ribs were thick but simple, straight and thick, with rounded tubercles, the sides and near the sifonal edge. No one knows with certainty what was the result of this coastal development, it seems however, that the shells were thick and ornamented ammonites characteristic of the last note. Among other kinds of Acantoceratinae, remember Mantelliceras. Acanthoceras was a warning of average size, which easily reach the shell diameter of about ten centimeters. One of the best known species is Acanthoceras rhotomagense.
