Description

Genuine Arnioceras Ammonites in Life Position – Cut and Polished Jurassic Fossil Display

Offered here is an outstanding and highly decorative fossil specimen of Arnioceras ammonites preserved in life position, beautifully cut and polished to reveal remarkable internal detail and natural arrangement. This exceptional piece comes from the world-famous Lower Lias Formation of the Lower Jurassic, collected from the legendary fossil cliffs of Lyme Regis, Dorset, England, part of the UNESCO-listed Jurassic Coast.

Ammonites preserved in life position are particularly sought after, as they provide an extraordinary snapshot of ancient marine life exactly as it settled on the Jurassic seafloor. The careful cutting and polishing enhances both scientific interest and aesthetic value, creating a stunning display fossil suitable for any serious collection.

The photographs show the exact specimen you will receive, with full sizing clearly visible in the provided images.

Every fossil we offer is a genuine specimen, and this piece includes a fully hand-signed Premium Certificate of Authenticity, providing lifetime assurance, provenance, and exceptional collector confidence.

Geological Setting – Lower Lias, Lower Jurassic of Lyme Regis

This specimen originates from the famous Lower Lias strata of Lyme Regis, dating to approximately 190–200 million years ago, during the Early Jurassic. At this time, southern England was submerged beneath a warm, shallow sea rich in ammonites, belemnites, fish, and marine reptiles.

The Lower Lias is renowned worldwide for its fossil abundance and exceptional preservation. Fine muds and limestones were deposited on the seabed under low-energy conditions, allowing shells to be rapidly buried and fossilised in place.

Lyme Regis has been one of the most important fossil localities in the history of paleontology, producing spectacular ammonites and marine reptiles for centuries.

Fossil Species – Arnioceras Ammonites

Arnioceras is a well-known Early Jurassic ammonite genus belonging to the subclass Ammonoidea, within the class Cephalopoda. Ammonites were marine molluscs closely related to modern squid and cuttlefish, and they were among the most successful predators of Jurassic seas.

Arnioceras is characterised by its tightly coiled shell with strong ribbing and elegant whorl structure. These ammonites are important index fossils for Lower Jurassic strata and provide valuable insight into early ammonite evolution and marine biodiversity.

Life Position Preservation – A Rare Fossil Snapshot

What makes this specimen especially remarkable is the preservation of multiple ammonites in life position, meaning they remain arranged naturally as they settled on the seabed millions of years ago. Such preservation is rare, as most ammonites are found scattered or fragmented.

Life-position ammonites offer a unique glimpse into Jurassic ecology, showing how these animals lived, died, and were buried in ancient marine sediments. This adds significant scientific and display value compared with isolated specimens.

Cut and Polished Finish – Enhanced Detail and Beauty

This fossil has been carefully cut and polished to reveal the ammonites’ internal structures and the natural contrasts within the surrounding limestone matrix. Polished ammonite displays are highly prized because they combine fossil authenticity with refined visual appeal, making them ideal for collectors, interior displays, or museum-style presentations.

The polished surface highlights the spiral geometry and fossilised shell material, transforming this into a true statement piece.
