Devonian Age, 350 million years old

Hexagonaria is an extinct genus of rugose coral that lived in ancient seas during the Devonian period, approximately 350 million years ago. These corals formed massive colonies composed of closely packed, six-sided corallites, giving the fossil its distinctive geometric appearance.

Specimens are preserved in Devonian limestone deposits and are commonly found in Morocco, particularly within the Sahara Desert and Assa Zag region. When polished, the internal skeletal structures become visible, including a central columella and radiating septae, which once supported the soft-bodied coral animals.

Closely related forms occur in Michigan, USA, where Hexagonaria percarinata is known as the Petoskey stone. Today, Hexagonaria fossils are valued both for their scientific significance and their decorative beauty, making them popular among collectors and artisans alike.
