🦑 Fossil Overview:

This is a RARE and well-preserved Cenoceras excavatum Fossil Nautilus from the Bajocian Stage of the Middle Jurassic (~170 million years old), sourced from Eurecy Calvados, France. Cenoceras is a genus of extinct nautiloids that thrived in Jurassic seas, characterized by its beautifully coiled and chambered shell, which provided buoyancy control.

Unlike ammonites, which have intricate suture patterns, Cenoceras excavatum exhibits a simpler, chambered shell structure, making it a significant evolutionary link between ancient and modern cephalopods. This fossil provides a fascinating glimpse into Jurassic marine ecosystems and the adaptation of cephalopods over time.

This particular specimen originates from the Alice Purnell Collection, one of the largest and most renowned ammonite and cephalopod fossil collections in the world. Fossils from this collection are highly sought after, ensuring this piece holds both scientific and historical significance.

 

🪨 Geological & Scientific Details:

• Species: Cenoceras excavatum
• Group: Nautiloid Cephalopod
• Age: Jurassic (Middle Jurassic, Bajocian Stage, ~170 Million Years Ago)
• Formation: Marine Deposits of Eurecy Calvados
• Location: Eurecy Calvados, France
• Shell Features: Coiled and chambered structure with subtle growth lines
• Preservation: Exceptional preservation with clearly defined chambers and excellent surface details

Cenoceras species like C. excavatum thrived in warm, shallow Jurassic seas, using their chambered shells for buoyancy control. Their evolutionary adaptations played a crucial role in cephalopod history, bridging the gap between ammonites and modern nautiluses.
