1.25" Fossil Goniatite (Prionoceras) - Morocco
This is a 1.25" fossil goniatite (Prionoceras sp.) that was collected near Quidane Cheppi, Morocco. The outer shell has been polished away, revealing the intricate suture pattern of the inner shell.
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.
