Devonian Age, 350 million years old

During the Devonian Period, shallow tropical seas supported extensive coral reef systems dominated by rugose corals such as Hexagonaria. This genus formed large colonial structures composed of tightly packed, polygonal corallites, most commonly hexagonal in shape. Each corallite contains a central columella with radiating septae, creating a complex skeletal architecture that reflects both the growth pattern of the colony and the biological structure of the individual coral polyps.

Hexagonaria fossils are well documented from Devonian deposits in both North Africa and North America. The Assa Zag region of Morocco is a notable source, while in the United States, Michigan’s Devonian limestones yield the iconic Petoskey stones. Polished specimens expose the internal coral anatomy in striking geometric detail, allowing scientists and collectors alike to study coral morphology while appreciating the aesthetic beauty of these ancient reef builders.
