Fossil Goniatite Keychain

This is a keychain featuring a polished, Goniatite fossil fro the Atlas Mountain Range of Morocco. These Goniatites are Devonian in age or approximately 400 million years old.

Goniatites possessed a shell, which is 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.
