Golden Pyrite Cluster Ammonite Fossil Jurassic Coast Dorset UK Lower Lias Black Ven Marls Charmouth Lyme Regis COA Included

Description

Genuine Golden Pyrite Ammonite Cluster – Jurassic Coast Fossil Treasure from Dorset

Offered here is a stunning golden pyrite ammonite cluster fossil, a rare and highly decorative natural grouping of multiple ammonites preserved together in brilliant metallic pyrite. This exceptional specimen comes from the famous Black Ven Marls of the Lower Lias Formation, collected along the world-renowned Jurassic Coast of Dorset, England.

The locality is Stonebarrow Cliff, Charmouth, Lyme Regis, one of Europe’s most celebrated ammonite fossil sites, internationally famous for producing beautifully preserved Early Jurassic marine fossils. Cluster specimens like this are especially desirable, as they preserve several ammonites together, creating a dramatic snapshot of ancient seafloor life.

This is a carefully chosen piece, selected for its outstanding visual appeal, strong pyrite mineralisation, and excellent display quality. The photographs show the exact fossil you will receive, with full sizing details clearly visible in the provided images.

Every fossil we offer is a genuine specimen, and this ammonite cluster includes a Certificate of Authenticity with lifetime guarantee, supplied as a generic authenticity card for permanent documentation and complete buyer confidence.

Importantly, this specimen was discovered by our own experienced team members, Alister and Alison, on 24 January 2026, and has been professionally cleaned, prepped, and treated by Alison, ensuring excellent presentation and long-term stability.

Geological Setting – Black Ven Marls, Lower Lias

This fossil originates from the famous Black Ven Marls, part of the Lower Lias Group, dating to the Early Jurassic approximately 190–200 million years ago. During this period, Dorset lay beneath a warm, shallow marine sea filled with ammonites, belemnites, fish, and marine reptiles.

The marls were deposited in a quiet offshore environment where fine sediments settled onto the seabed. Low oxygen conditions helped reduce decay and scavenging, allowing ammonite shells to fossilise in remarkable detail.

Stonebarrow Cliff and the Charmouth coastline are among the most important fossil localities in the UK, making specimens from this area extremely collectible.

Fossil Type – Ammonite Cluster

Ammonites were extinct marine cephalopods, closely related to modern squid and cuttlefish. Their beautifully coiled shells are among the most iconic fossils in the world and were once abundant predators of Jurassic seas.

Cluster fossils are particularly special because they preserve multiple ammonites together within the same block of matrix, offering a richer and more visually striking specimen than a single shell. These clusters represent moments where shells accumulated on the seabed before burial and fossilisation.

Such specimens are prized by collectors for both their scientific interest and impressive natural formation.

Golden Pyrite Mineralisation – Natural Metallic Beauty

This specimen displays exceptional golden pyrite preservation, often called “fool’s gold.” Pyrite forms during fossilisation when the original shell material is replaced or infilled by iron sulphide minerals, creating a brilliant metallic lustre.

The contrast of glowing pyrite ammonites against the Jurassic matrix makes this fossil a true standout display piece. Pyritised ammonite clusters are especially sought after because they combine deep-time fossil history with stunning mineral beauty.

Preparation, Provenance and Authenticity

This is a 100% genuine golden pyrite ammonite cluster fossil, responsibly collected from Stonebarrow Cliff by Alister and Alison, and expertly cleaned, prepared, and stabilised by Alison for long-term preservation.

A lifetime Certificate of Authenticity is included with every purchase, ensuring complete confidence in provenance and genuineness.
