Nautilus Pseudoelegans Nautiloid Fossil Cretaceous Sussex UK COA Glynde Lower Cenomanian Upper Cretaceous

Description

Genuine Nautilus pseudoelegans Nautiloid Fossil from Glynde, East Sussex

This is a genuine Nautilus pseudoelegans nautiloid fossil from Glynde, East Sussex, UK, dating to the Lower Cenomanian Stage of the Upper Cretaceous. Nautiloids are among the most fascinating marine fossils, representing an ancient group of shelled cephalopods that survived for hundreds of millions of years and still have living relatives today in the modern Nautilus. This specimen is a carefully chosen fossil, with the photograph showing the actual piece you will receive. Full sizing can be seen in the photo.

This fossil also includes a Certificate of Authenticity lifetime guarantee generic card, making it a desirable specimen for fossil collectors, Cretaceous fossil displays, educational collections, natural history cabinets, and anyone interested in authentic British marine fossils.

Fossil Type and Species

Nautilus pseudoelegans is a fossil nautiloid, a shelled marine cephalopod related to modern nautiluses and more distantly related to ammonites, squid, and cuttlefish. Unlike ammonites, which became extinct at the end of the Cretaceous, nautiloids belong to a long-lived cephalopod lineage with a deep evolutionary history stretching back into the Palaeozoic Era.

Nautiloids lived inside coiled, chambered shells. The animal occupied the outer body chamber, while the internal chambers helped control buoyancy through gas and fluid regulation. This allowed the nautiloid to move through the water column, rising or descending as needed. The shell of Nautilus pseudoelegans would have offered protection while also acting as a buoyancy device, making it a highly successful marine form.

The genus Nautilus is known for its smooth to gently ornamented, involute coiled shell shape. In fossil specimens, the outer shell surface may preserve natural growth lines, chamber outlines, sutures, shell curvature, and mineralised texture. These features make nautiloid fossils visually attractive while also preserving important information about ancient cephalopod life.

Lower Cenomanian Upper Cretaceous Age

This specimen dates to the Lower Cenomanian, the earliest part of the Cenomanian Stage within the Upper Cretaceous Period. The Cenomanian began around 100 million years ago and was a time of high global sea levels, when large areas of Europe, including much of southern England, were covered by warm marine waters.

During the Lower Cenomanian, the seas around what is now East Sussex supported a rich marine ecosystem. Nautiloids shared these waters with ammonites, bivalves, gastropods, echinoids, brachiopods, fish, marine reptiles, and other invertebrates. The presence of nautiloids in these deposits gives a direct link to the open marine conditions of the Cretaceous seas that once spread across southern Britain.

Glynde, East Sussex Geological Setting

Glynde in East Sussex lies within one of Britain’s important Cretaceous fossil-bearing regions. The Lower Cenomanian rocks of this area are associated with the early stages of the Upper Cretaceous marine transgression, when rising seas deposited sediments across southern England. These deposits may include chalky, glauconitic, sandy, or calcareous marine layers depending on the local stratigraphy.

The Cenomanian rocks of Sussex are part of the wider Cretaceous succession of southern Britain, famous for preserving marine fossils from a time when the region was far warmer and lay beneath shallow seas. Fossils from this setting are valuable because they record a major period of marine flooding and environmental change, leading into the widespread chalk seas that later dominated the Cretaceous landscape.

Nautiloid Morphology and Display Features

Nautilus pseudoelegans has the classic coiled nautiloid form that makes these fossils especially appealing. The shell is typically planispiral and involute, meaning the later whorls wrap around and cover much of the earlier shell. This gives the fossil a compact, rounded, elegant appearance, distinct from many ribbed ammonites of similar age.

The natural features of this fossil may include shell curvature, chambered internal structure, sutures, surface growth marks, mineral staining, matrix, and signs of natural preservation. These details are part of the specimen’s authentic geological character and reflect its long fossilisation history after burial in Cretaceous marine sediment.

As a display piece, this Nautilus pseudoelegans fossil offers strong visual appeal and scientific interest. It is suitable for collectors of British fossils, Cretaceous marine fossils, nautiloids, cephalopods, and natural history specimens. Its East Sussex locality and Lower Cenomanian age make it a particularly interesting example of Britain’s Upper Cretaceous fossil record.

Certificate of Authenticity Included

This Nautilus pseudoelegans nautiloid fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The photograph shows the actual fossil you will receive, making this a carefully selected individual piece rather than a stock image.

With its Lower Cenomanian age, Upper Cretaceous origin, Glynde locality, and classic nautiloid form, this fossil is a collectable and educational specimen that represents the ancient marine life of East Sussex during one of the most significant sea-level highstands in Earth history.
