Description
This listing features a scientifically valuable and beautifully preserved fossil nautilus of the genus Cenoceras from the Cretaceous period, found in the fossil-rich region of Saint-Maixent-l’École, France. This piece is part of the distinguished Alice Purnell Collection, known for its museum-grade, historically documented fossil specimens.
Cenoceras is a genus of extinct nautiloid cephalopods that existed from the Late Triassic to the Cretaceous. These marine molluscs were characterised by smooth, rounded shells and simple suture patterns. They are considered close relatives of modern nautiluses but display evolutionary traits unique to ancient oceans. With a coiled shell composed of internal chambers, Cenoceras used gas regulation to navigate the seas as a free-floating predator and scavenger.
This specimen offers excellent preservation, highlighting the classic coiling and chamber arrangement of the nautilus shell.
Geological Context: The Cretaceous period (145–66 million years ago) was a time of high sea levels and thriving marine ecosystems across Europe. The region of Saint-Maixent-l’École in western France is well known for producing marine fossils from Cretaceous sediments, including ammonites, nautiloids, and bivalves. Fossils from this area often show excellent preservation due to the fine-grained limestone and marl formations.
