3.95" Fossil Heteromorph (Nostoceras) Ammonite - Madagascar

This is a really cool heteromorph ammonite (Nostoceras sp.) fossil from 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.

Almost all of the surrounding limestone has been painstakingly removed to provide the best picture of the entire ammonite. There are some repaired cracks through the specimen and the thinnest end is incomplete.

The base of the rock has been cut flat for presentation.
