Ammonites were extinct marine cephalopods that thrived in the oceans during the Mesozoic Era, approximately 250 to 66 million years ago. The fossil highlights the elegant geometry of ammonite shells and serves as an important reference for studying ancient marine environments and geological time. It holds both scientific significance and strong appeal for collectors and display.
