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, approximately 350 million years ago. These corals developed as large, rounded colonies made up of tightly packed six-sided corallites, creating the distinctive geometric patterns visible in fossil specimens.
Hexagonaria fossils occur in Devonian-age limestone formations, with well-known examples coming from Morocco, particularly the Sahara Desert and the Assa Zag region. When cut and polished, the fossil reveals fine internal structures, including a central columella and radiating septae, which formed the skeletal framework of the ancient coral polyps.
Closely related to the well-known Petoskey stone of Michigan, USA, identified as Hexagonaria percarinata, these fossils are admired for their natural range of colors—from pale creams to rich brown tones. Today, polished Hexagonaria coral is prized for jewelry, decorative objects, and fossil collections, blending geological history with striking visual appeal.
