Description from the seller
The ammonite Cleoniceras is a mollusk that lived during the Late Cretaceous, approximately 100 to 65 million years ago. This fossil shell features a pronounced spiral and a flattened central part, characterized by leaf-shaped suture lines. The aperture is well preserved, and the coloration varies from light brown to dark brown with shades of orange, due to the presence of aragonite.
The shells of Cleoniceras are a valuable resource for geologists and evolutionists, as they provide information on the biodiversity and environmental conditions of Earth during the Mesozoic. This unique piece is a significant addition to any collection or as a decorative element in your home or office.
