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, around 350 million years ago. Its colonies were composed of numerous tightly packed, hexagonal skeletal cups, each with a central structure and radiating septae. This complex architecture creates the signature honeycomb and floral patterns that become especially vivid when the fossil is polished.

These fossils are best known from two major regions: the Sahara Desert of Morocco and the Great Lakes region of the United States. In Michigan, Hexagonaria percarinata is referred to as the Petoskey stone and holds official state stone status. Polished Hexagonaria reveals a wide range of natural earth tones, making it popular for use in lapidary art, home décor, and educational displays. At the same time, these fossils offer valuable insight into Devonian coral reef systems and early marine biodiversity.
