Description
Exceptional 7” Fossil Nautilus – Cymatoceras elegans
This rare and highly collectible 7-inch Fossil Nautilus, identified as Cymatoceras elegans, is a striking example of Late Jurassic marine life from Lewes, Kent, United Kingdom. Nautiloids are an ancient lineage of cephalopods, closely related to modern Nautilus species, and are prized by collectors for their elegant coiled shells and deep evolutionary significance. This particular specimen has been carefully selected for its aesthetic appeal, preservation quality, and display presence, making it an outstanding addition to any fossil collection.
Geological Context – Late Jurassic Marine Environment
Dating to the Late Jurassic period, approximately 163 to 145 million years ago, this fossil originates from marine sedimentary deposits in the Lewes region of Kent. During this time, much of southern England was submerged beneath a warm, shallow epicontinental sea. These environments were rich in marine biodiversity, including ammonites, belemnites, marine reptiles, and nautiloids like Cymatoceras. The fine-grained sediments allowed for excellent fossil preservation, often retaining detailed shell morphology and structural features.
Fossil Type & Taxonomy
Cymatoceras elegans belongs to the subclass Nautiloidea, order Nautilida, and family Cymatoceratidae. Nautiloids are characterised by their chambered shells, which were used for buoyancy control via gas exchange within internal chambers (camerae). Unlike ammonites, nautiloids typically display simpler suture patterns and smoother shell ornamentation, contributing to their distinctive, elegant appearance.
Morphology & Notable Features
This specimen exhibits the classic planispiral coiling associated with nautiloids, with a gently expanding whorl structure. The shell displays subtle ribbing and growth lines, indicative of its natural development in a stable marine environment. The chambers are separated by septa, and although the internal siphuncle is not always visible externally, it played a crucial role in the organism’s buoyancy regulation. The overall symmetry and preservation make this a visually striking piece suitable for both study and display.
Authenticity & Presentation
This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee card, ensuring confidence in its provenance. The photograph provided shows the exact fossil you will receive, offering full transparency and assurance of quality. Each piece is carefully handled and selected to meet high standards for collectors, educators, and enthusiasts alike.
Collector Appeal & Display Value
With its impressive 7-inch size, this Cymatoceras elegans fossil makes a commanding display piece. Nautiloid fossils are less commonly encountered than ammonites, adding to their desirability and rarity. Whether you are an experienced fossil collector or seeking a unique natural history item, this specimen represents both scientific interest and aesthetic beauty, capturing a moment of life from the Jurassic seas of Britain.
