Cenoceras inornatum Nautilus Fossil – Cornbrash Formation, Callovian, Jurassic – Shorncote, Gloucestershire, UK – Alice Purnell Collection

Description 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.   Item Details: Specimen: Cenoceras inornatum Nautilus Age: Callovian, Middle Jurassic (~165 million years ago) Geological Formation: Cornbrash Formation Location: Shorncote, Gloucestershire, United Kingdom Source: Alice Purnell Collection Certificate of Authenticity: Included Scale Reference: Scale rule square/cube = 1cm.
