Cenoceras Fossil Nautilus Upper Toarcian Jurassic Alice Purnell Collection Specimen – Certificate of Authenticity

Original price was: £24.00.Current price is: £19.20.

This is a rare and well-preserved Cenoceras inornatum 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 inornatum 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 inornatum
  • Stage: Upper Toarcian, Early Jurassic (~180 million years ago)
  • Location: Ilminster, United Kingdom
  • Depositional Environment: Shallow marine seabed with rich cephalopod diversity

Description

Identification

This listing features a Cenoceras fossil nautilus, identified as Upper Toarcian, Jurassic. Cenoceras is associated with the long geological history of nautiloid cephalopods, a group of marine animals recognised for their chambered shells. This specimen is presented as a fossil nautilus for collectors, educators, natural history enthusiasts and anyone interested in Jurassic palaeontology.

The supplied identification, “CENOCERAS Fossil Nautilus,” highlights the specimen’s principal fossil designation. Its Upper Toarcian, Jurassic identification places it within a significant interval of Earth history when marine ecosystems supported a diverse range of shelled cephalopods and other invertebrate life.

Geological Context

The Toarcian is a recognised stage of the Jurassic Period. As a geological interval, it is important to the study of Jurassic marine life and the fossils preserved from ancient marine environments. Nautiloids are cephalopod molluscs with internally divided shells. Their chambers played an important role in buoyancy, while the shell provided a durable structure capable of fossilisation under suitable burial and preservation conditions.

A fossil nautilus such as Cenoceras offers an engaging connection to Jurassic palaeontology because it represents both biological form and geological history. The chambered-shell plan of nautiloids is especially valuable for teaching and display, helping illustrate how extinct marine organisms can be studied through their preserved hard parts. The geological designation supplied for this item should be retained with the specimen as part of its identification information.

Collection and Authenticity

This specimen is From the Alice Purnell Collection. It is suited to a fossil cabinet, teaching collection, geology display, museum-inspired interior, or a personal natural history collection. The combination of a named fossil nautilus, Upper Toarcian identification and Jurassic age designation makes it an appealing piece for collectors who value clearly described geological specimens.

This Fossil is a genuine specimen and Includes a Certificate of Authenticity lifetime guarantee generic card.

The certificate wording is supplied with the item as stated above. Please keep the certificate with the fossil for future reference, display, and collection documentation.
