3.9" Wide Polished Goniatite From Morocco

This is a polished fossil Goniatite, a close relative of ammonites (same Subclass). These Goniatites are Devonian in age and are quarried from the Atlas Mountains in Morocco.

The specimen has obviously been broken and put back together, with a missing section replace with rock, hence the bargain price.

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.
