This listing presents a genuine and rare Cenoceras inornatum Nautilus Fossil from the Cornbrash Formation, dated to the Callovian Stage of the Middle Jurassic Period, approximately 165 million years ago. It was discovered in Shorncote, Gloucestershire, United Kingdom, and is part of the esteemed Alice Purnell Collection.

Cenoceras inornatum belongs to the extinct genus of nautiloid cephalopods, relatives of modern-day nautiluses. These marine creatures were characterised by their smooth, planispiral shells, and were highly mobile predators of ancient seas. Unlike ammonites, which have more complex suture patterns, nautiloids like Cenoceras had simpler chamber structures and suture lines, often exhibiting a more symmetrical and evenly coiled shell.

The Cornbrash Formation is a notable Middle Jurassic geological unit composed of shelly, fossil-rich limestone and marl. Found throughout southern and central England, it yields exceptionally preserved marine fossils, including ammonites, nautiloids, bivalves, and echinoids. The marine deposits reflect warm, shallow sea conditions that were ideal for fossil preservation.

This fossil specimen is a natural, unpolished whole Nautilus shell that beautifully exhibits the classic coiled symmetry of the species. It is a striking display piece for fossil collectors, educators, or natural history enthusiasts seeking a genuine and uncommon Jurassic-era cephalopod.

Description

Cenoceras INORNATUM Nautilus Fossil

This listed specimen is identified as Cenoceras INORNATUM, a fossil nautilus from the Cornbrash Formation, Callovian, Jurassic. It is associated with Shorncote, Glouchestershire, United Kingdom, and forms an appealing addition to collections focused on ammonites, nautiloids, Jurassic palaeontology and British fossil geology.

Geological Context

The Callovian is a stage of the Jurassic Period and is widely recognised as part of the Middle Jurassic. Fossils from this interval are valued for documenting marine life and the changing environments of Jurassic seas. The Cornbrash Formation is a Jurassic rock unit associated with marine deposits in Britain, making this identification especially relevant to collectors interested in the geological history of the United Kingdom.

Nautilus Fossil Collecting

Cenoceras belongs to the broader group of nautiloid cephalopods. Nautiloids are shelled marine animals with a long fossil record, and their chambered shells are important in the study of ancient marine ecosystems and cephalopod evolution. A named Cenoceras specimen can provide an interesting focus for a display covering Jurassic life, fossil cephalopods, historical geology or the development of chambered shells through deep time.

The combination of a formal identification, Callovian age and Cornbrash Formation association gives this fossil strong educational and display appeal. It can be used as a conversation piece in a home collection, classroom setting, geological study area or natural history display. The Jurassic designation also places the specimen within one of the best-known intervals of Earth history, when marine ecosystems included a wide range of shelled invertebrates and other fossil organisms.
