8.2" Tall Cluster Of Heteromorph (Nostoceras) Ammonite Fossils

This is a fantastic cluster of seven different heteromorph ammonite (Nostoceras) fossils from the Menabe Region of Madagascar. Unlike most ammonites that lived in tightly coiled, spiral shell that retains their shape throughout the cephalopod's life, heteromorph ammonites have irregularly-coiled or uncoiled shells. These hetermorph ammonites are Late Cretaceous in age (Campanian Stage) or approximately 70 million years old.

The piece has been well prepared from the hard limestone to expose the fossils and create an aesthetic display piece. The base of the stone has been cut flat so that is stands up on a hard surface without the need for a display stand. Some of the ammonites have some restoration to the smallest coil on the end which is often not well preserved.
