🦑 Fossil Overview:

This is a RARE and well-preserved Didymoceras landmanni Fossil Nautilus from the Bajocian Stage of the Middle Jurassic (~170 million years old), sourced from Euzercy Calvados, France. Didymoceras is a genus of extinct nautiloids known for its distinctive coiled and chambered shell, which allowed it to regulate buoyancy in ancient seas.

Unlike ammonites, which exhibit intricate suture patterns, Didymoceras landmanni has a robust, simpler chambered structure, making it an important evolutionary link in the history of cephalopods. This fossil provides significant insight into Jurassic marine ecosystems and the adaptation of nautiloid species 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: Didymoceras landmanni
• Group: Nautiloid Cephalopod
• Age: Jurassic (Middle Jurassic, Bajocian Stage, ~170 Million Years Ago)
• Formation: Marine Deposits of Euzercy Calvados
• Location: Euzercy Calvados, France
• Shell Features: Coiled and chambered structure with visible growth lines
• Preservation: Excellent structural integrity with clearly defined chambers and surface details

Didymoceras species like D. landmanni thrived in warm, shallow Jurassic seas, using their chambered shells for buoyancy control. While ammonites dominated certain marine ecosystems, nautiloids like Didymoceras were an essential part of the cephalopod lineage that led to modern-day nautiluses.
