Perisphinctes is a genus of ammonites that lived during the Jurassic period, approximately 180 to 160 million years ago. These marine animals were relatively large, with adult shells measuring up to 1 meter in diameter.

Perisphinctes ammonites are characterized by their distinctive ribbing and coiled shape, as well as their intricate suture patterns. The shells of these animals were generally thick and sturdy, which helped to protect them from predators and other environmental hazards.

The fossils of Perisphinctes ammonites are found in many parts of the world, including Europe, North America, and Asia. Some of the most well-known sites for Perisphinctes fossils include the limestone and shale deposits of France, Germany, and England.

The study of Perisphinctes ammonites is an important part of paleontology, providing valuable insights into the evolution and diversification of these ancient marine animals. These fossils are particularly important for reconstructing the paleoecology and paleogeography of the Jurassic period, as they are often found in association with other marine fossils, such as bivalves, belemnites, and other ammonites.

Overall, Perisphinctes ammonites are a fascinating and important part of the fossil record, providing valuable insights into the history of life on Earth during the Jurassic period. Their unique morphology and intricate suture patterns continue to captivate and inspire scientists and enthusiasts alike.
