Devonian Age, 350 million years old

Hexagonaria is an extinct genus of colonial rugose coral that lived in warm, shallow seas during the Devonian Period, approximately 350 million years ago. These corals formed large colonies made up of tightly packed, hexagonal corallites. Each corallite contains a central columella and radiating septae, producing the characteristic honeycomb and flower-like patterns that have made Hexagonaria fossils highly recognizable and collectible.

Important fossil localities include the Assa Zag region of the Sahara Desert in Morocco and Devonian limestone deposits in Michigan, USA. In Michigan, the species Hexagonaria percarinata is commonly known as the Petoskey stone and is designated as the official state stone. When polished, Hexagonaria coral reveals striking geometric patterns and natural earth tones ranging from cream and gray to rich browns and tans. These fossils are widely used in lapidary art, jewelry making, and decorative objects, while also serving as valuable scientific specimens that provide insight into Devonian reef ecosystems and early coral evolution.
