Original price was: £48.00.Current price is: £38.40.

This is a rare and well-preserved fossil of Cenoceras lineatus, a species of extinct nautiloid cephalopod from the Inferior Oolite Formation, Bajocian stage of the Middle Jurassic (~170 million years ago), found in Oxfordshire, United Kingdom.

Cenoceras is a genus of nautiloids that thrived in Jurassic seas, possessing a smooth, coiled shell with faint growth lines and a streamlined form. Unlike ammonites, nautiloids had simpler internal chamber structures and lacked complex ribbing, making them efficient swimmers and skilled hunters.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
