Devonian Age, 350 million years old

Hexagonaria is an extinct genus of colonial rugose corals that thrived in warm, shallow seas during the Devonian Period, approximately 350 million years ago. These corals formed large, interconnected colonies made up of tightly packed, hexagonal corallites. Each corallite contains a central columella surrounded by radiating septae, creating the distinctive honeycomb or flower-like pattern that makes Hexagonaria fossils instantly recognizable.

Specimens are found in several important fossil localities, including the Sahara Desert of Morocco (Assa Zag region) and the Great Lakes region of North America. In Michigan, the species Hexagonaria percarinata is famously known as the Petoskey stone and is designated as the official state stone. When cut and polished, these fossils reveal beautiful geometric patterns in shades of cream, gray, tan, and brown, making them highly sought after for lapidary work, jewelry, and decorative displays. Beyond their aesthetic appeal, Hexagonaria fossils provide valuable insight into Devonian reef ecosystems and the evolution of early coral communities.
