Hexagonaria coral is a type of fossil coral that dates back to the Devonian period, approximately 350 million years ago [1] [2].
Characteristics and Origin
Value and Uses
Hexagonaria is a genus of colonial rugose coral [2]. These corals are characterized by their hexagonal patterns and intricate details, which are often highlighted through polishing [3]. They are commonly found in large, rounded heads [4]. The fossils are found in rock formations dating back to the Devonian period [2]. Hexagonaria fossils are found in Morocco, specifically in the Sahara Desert [4] and the Assa Zag region [2] [3].
Additional Information
Polished Hexagonaria coral is valued for its aesthetic qualities and is used in jewelry, home décor, and collections [3]. The natural hues range from soft creams and browns to deeper shades, making each specimen unique [3].
The Hexagonaria coral fossils from Morocco are from the Devonian period, approximately 350 million years old.
Hexagonaria is similar to the Petoskey stone found in Michigan [2] [3]. The Hexagonaria percarinatum species is commonly found in Michigan [8]. The corallites of Hexagonaria have a central pillar called a columella, with radiating features called septae [8].
