This is a rare and well-preserved Cenoceras inornatum fossil nautilus from the Bajocian Stage of the Middle Jurassic (~170 million years ago). This specimen was discovered at Hurcott Road Cutting, Ilminster, Somerset, UK, a well-known site for Jurassic marine fossils.

Cenoceras inornatum is an extinct species of nautiloid cephalopods. Unlike ammonites, which feature complex suture patterns, nautiloids like Cenoceras have a simpler internal chambered shell structure. These marine predators used their gas-filled chambers for buoyancy, allowing them to move efficiently through Jurassic seas while preying on smaller marine organisms.

  • Species: Cenoceras inornatum
  • Stage: Bajocian, Middle Jurassic (~170 million years ago)
  • Formation: Inferior Oolite
  • Location: Hurcott Road Cutting, Ilminster, Somerset, United Kingdom

Description

This is a rare and well-preserved Cenoceras fossil nautilus from the Upper Toarcian stage of the Jurassic (~180 million years ago). It was discovered in Ilminster, United Kingdom, a significant fossil locality known for its exceptional preservation of marine life from the Early Jurassic seas.

Cenoceras belongs to the extinct nautiloid family Nautilidae. Unlike ammonites, which had complex suture patterns, nautiloids like Cenoceras feature simpler internal chambers used for buoyancy control. These ancient marine cephalopods were slow-moving predators that thrived in warm, shallow Jurassic seas.

The Toarcian Stage is a well-documented geological period, marking an important evolutionary phase in marine ecosystems. The fossil-rich deposits of Ilminster have yielded a diverse array of marine fossils, including ammonites, bivalves, and nautiloids, making it an essential site for Jurassic paleontology.

GEOLOGICAL INFORMATION:

 * Species: Cenoceras 

 * Stage: Upper Toarcian, Early Jurassic (~180 million years ago)

 * Location: Ilminster, United Kingdom

 * Depositional Environment: Shallow marine seabed with rich cephalopod diversity

FOSSIL CHARACTERISTICS:

 * Well-preserved chambered nautilus shell

 * Visible growth lines and suture details

 * Smooth coiling with characteristic nautiloid shape

 * A significant specimen from a well-documented Jurassic site

ADDITIONAL INFORMATION:
