2.8" Polished Fossil Goniatite Cluster - Germany

This is a section of cut and polished sedimentary rock that contains goniatites and countless shell fragments. It was collected from the Winterberg Quarry near Bad Grund in Harz, Niedersachsen, Germany. Two sides of this section of rock have been polished to bring out the goniatite and shell fragments in detail.

Goniatites possessed a shell which was divided internally into chambers filled with gas for buoyancy. An open chamber at the front of the shell provided living space for the animal. The general morphology and habit of goniatites was probably similar to that of their later relatives the ammonites, being free swimming and possessing a head with two well developed eyes and arms.
