Here is an exceptional Fossil specimen as it’s two Geisonoceras together from the Western desert of Morocco in North Africa. Both Cephalopods have excellent distinctive Geisonoceras signature detail in the zig-zag suture design of the chambers and have a smoothed unpolished surface. The very cool large Geisonoceras measures almost 8 1/2″ x nearly 6 7/8″ x 1 5/8″ thick with the smaller one being over 3″ x almost 2 1/2″ x 3/4″. Together, the entire specimen measures almost 8 1/2″ x 7 3/4″ x 2 3/8″ and weighs 4 1/8 pounds. A truly wonderful addition to any fossil collection!

The Geisonoceras Ammonoids are extinct members of the cephalopod group of mollusks. Only a limited number of species have survived to the present day which includes the squid and the chambered nautilus. Like their younger relative Ammonites, they had a multi-chambered shell, and added more chambers as it grew, always living in the outer chamber. They thrived in the Devonian period some 400 to 350 million years ago.
