Every set includes a Certificate of Authenticity with a lifetime guarantee, confirming the genuine nature and provenance of these British fossils.

Geological Origin – Jurassic Coast, Dorset and Somerset

This fossil mix originates from the world-famous Jurassic Coast of southern England, specifically the fossil-rich regions of Dorset and Somerset. These deposits date to the Jurassic period, approximately 201 to 145 million years ago, a time when much of the UK was covered by warm, shallow seas.

The sedimentary formations in this region, including the Blue Lias and Charmouth Mudstone formations, are composed primarily of limestone and shale. These environments were ideal for the preservation of marine life, with fine sediments rapidly burying organisms and protecting them from decay.

The Jurassic Coast is a UNESCO World Heritage Site, recognised globally for its geological significance and exceptional fossil record.

Fossil Types and Species Variety

This mixed fossil collection typically includes a diverse range of marine fossils representative of Jurassic ecosystems. Common fossil types found within such mixes include:

• Ammonites (Subclass Ammonoidea) – Spiral-shelled cephalopods with ribbed or ornamented shells, often displaying intricate patterns.
• Belemnites (Order Belemnitida) – Bullet-shaped internal guards from extinct squid-like cephalopods.
• Bivalves (Class Bivalvia) – Fossilised shells from ancient clams and oysters, often preserved with fine detail.
• Gastropods (Class Gastropoda) – Snail-like fossils with coiled shells, showing a variety of shapes and textures.
• Crinoid fragments (Class Crinoidea) – Segmented stem pieces from marine echinoderms, sometimes referred to as “sea lilies.”

These fossils represent a thriving marine ecosystem, preserved within sedimentary layers that capture a snapshot of Jurassic biodiversity.

Morphology and Preservation

Each fossil within this 1kg mix displays natural variation in shape, size, and preservation. Ammonites may show ribbing and coiling patterns, while belemnites exhibit smooth, tapered forms. Bivalves and gastropods often retain shell structures and surface textures, providing insight into their original biology.

The fossils have been carefully cleaned and prepared to highlight their natural features while maintaining their integrity. Many pieces retain their original matrix, adding authenticity and geological context to the collection.

Paleoenvironment and Marine Ecosystem

During the Jurassic period, Dorset and Somerset were part of a shallow tropical sea teeming with life. Ammonites and belemnites swam freely in the water column, while bivalves and gastropods lived on or within the seabed. Crinoids anchored themselves to the sea floor, filtering nutrients from the water.

Periodic sediment deposition from storms and environmental changes rapidly buried these organisms, leading to exceptional fossil preservation. This collection captures a broad representation of that ancient marine ecosystem.

Authenticity and Preparation

All fossils in this collection are genuine specimens, discovered by Alister and Alison and professionally prepared by Alison. Each piece has been handled with care to ensure both quality and authenticity. The included Certificate of Authenticity with lifetime guarantee provides reassurance of provenance and adds value for collectors.

The photographs show the exact set you will receive, ensuring complete confidence in your purchase.
