Description
Offered here is a genuine cut and polished ammonite fossil from the extinct genus Metalegoceras, dating to the Lower Permian period (~290 to 270 million years ago). This rare and beautifully preserved specimen originates from East Timor, Indonesia, a region known for yielding some of the most scientifically significant and visually striking marine fossils from the Permian.
Unlike Jurassic or Cretaceous ammonites, Metalegoceras belongs to a more ancient lineage of cephalopods that thrived long before the mass extinction that marked the end of the Permian. These ammonoids exhibit highly complex suture patterns and evolved forms well adapted to their warm, shallow marine environments.
This particular specimen has been expertly cut and polished, revealing the intricate internal chamber structures that once housed gas-filled compartments used for buoyancy. The result is a stunning fossil that highlights both the scientific importance and aesthetic beauty of ammonoid preservation.
The image includes a 1cm scale cube for accurate size reference. You will receive the exact fossil shown, and it comes with a Certificate of Authenticity.
