Cenoceras Nautilus Fossil – Polished & Sectioned – Jurassic Inferior Oolite, Burton Bradstock Dorset UK – Authentic British Fossil with Certificate

This listing features a beautifully sectioned and polished Cenoceras Nautilus fossil, discovered on the world-renowned Jurassic Coast at Burton Bradstock, Dorset, UK. Dating to the Jurassic Period and preserved in the Inferior Oolite Formation, this specimen is a stunning example of ancient marine life that thrived over 170 million years ago.

Cenoceras is a genus of extinct nautiloids—an ancient group of cephalopods that includes modern nautiluses and are closely related to squid and octopuses. These marine creatures had coiled, chambered shells that allowed them to control buoyancy as they moved through the oceans. Unlike ammonites, Cenoceras featured smooth, rounded shells with less complex suture lines, giving them a more elegant appearance.

This specimen has been carefully sliced and polished, revealing the internal chamber structures of the shell. These chambers, once filled with gas or fluid, helped the animal maintain neutral buoyancy. The intricate patterns and natural mineralisation within the fossil create a striking visual appeal, making it a superb collector's item or unique decorative piece.

Your specimen was discovered by our own team members Alister and Alison on 17 January 2025 and has been meticulously cleaned, prepped, and treated by Alison for quality and preservation.

New Giant Nautilid species

a new species of Cenoceras, C. rumelangense, from the early Bajocian Humphriesianum Zone of Luxembourg and Southwest Germany. Heres an image of Robert Weis for human scale, followed by figures from the paper. The Cenoceras rumelangense n.sp., paratype from figure 9 is my favourite, look how wide this fellas opening is.

Got a bunch o' fossils in today! They'll be on Etsy pretty soon!

We got one shiny Nautilus lad.

And this tiny fish friend!

(Casual reminder to refrain from buying Nautilus shells, buy their already long dead fossils and leave the alive bois we still have alone pls!)

There was also supposed to be some Elrathia kingii Trilobite friends but they have mysteriously disappeared, not even the supplier knows where they went, come home lads...

Cenoceras Fossil Nautilus – Cretaceous – Saint-Maixent-l'École, France – Alice Purnell Collection – 100% Genuine with Certificate

This listing features a scientifically valuable and beautifully preserved fossil nautilus of the genus Cenoceras from the Cretaceous period, found in the fossil-rich region of Saint-Maixent-l'École, France. This piece is part of the distinguished Alice Purnell Collection, known for its museum-grade, historically documented fossil specimens.

Cenoceras is a genus of extinct nautiloid cephalopods that existed from the Late Triassic to the Cretaceous. These marine molluscs were characterised by smooth, rounded shells and simple suture patterns. They are considered close relatives of modern nautiluses but display evolutionary traits unique to ancient oceans. With a coiled shell composed of internal chambers, Cenoceras used gas regulation to navigate the seas as a free-floating predator and scavenger.

This specimen offers excellent preservation, highlighting the classic coiling and chamber arrangement of the nautilus shell.

Geological Context: The Cretaceous period (145–66 million years ago) was a time of high sea levels and thriving marine ecosystems across Europe. The region of Saint-Maixent-l'École in western France is well known for producing marine fossils from Cretaceous sediments, including ammonites, nautiloids, and bivalves. Fossils from this area often show excellent preservation due to the fine-grained limestone and marl formations.

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

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.
