Devonian Age, 350 million years old

Hexagonaria is an extinct colonial coral that flourished in Devonian oceans more than 350 million years ago, when vast shallow seas covered much of what is now North America and North Africa. This rugose coral formed massive colonies made up of tightly interlocking, polygonal chambers. These chambers, most commonly hexagonal, contain a central skeletal core and radiating internal walls that create the signature honeycomb appearance visible on fossil surfaces.

Notable fossil deposits occur in the Assa Zag region of the Moroccan Sahara and in the limestone formations of Michigan, USA. In Michigan, Hexagonaria percarinata is famously known as the Petoskey stone and has become a symbol of the state’s geological heritage. When polished, these fossils reveal beautifully defined floral and geometric patterns in soft creams, tans, grays, and deep, earthy browns. These striking natural designs make Hexagonaria a favorite for collectors, lapidary artists, and educational displays.
