Devonian Age, 350 million years old

Hexagonaria fossil coral is a classic example of Devonian marine life preserved in stone. Living approximately 350 million years ago, this extinct colonial rugose coral formed extensive reef-like colonies in warm, shallow seas. Each colony consists of tightly arranged, hexagonal corallites, each containing a central columella and radiating septae that produce the iconic honeycomb and flower-like patterns associated with Hexagonaria.

Important sources include the Assa Zag region of the Moroccan Sahara and Devonian limestone formations in Michigan, USA. In Michigan, Hexagonaria percarinata is commonly known as the Petoskey stone and is designated as the official state stone. When polished, these fossils reveal intricate geometric patterns and rich natural coloration, ranging from soft creams and grays to deeper tans and browns. These visually striking fossils are prized by collectors, jewelers, and educators alike, offering both aesthetic beauty and a tangible connection to ancient Devonian reef ecosystems.
