Authentic Tragophylloceras Fossil Ammonite from the Jurassic Coast

This listing is for a genuine Tragophylloceras fossil ammonite preserved within a naturally split nodule, collected from the famous Green Ammonite Beds of the Lower Lias along the Jurassic Coast at Stonebarrow Cliff, Charmouth, Lyme Regis, Dorset, UK. This location is a UNESCO World Heritage Site and is world-renowned for its exceptional preservation of early Jurassic marine life. The specimen you see in the photographs is the exact fossil you will receive. A scale cube of 1 cm is shown for accurate sizing reference, and full dimensions can be seen in the images provided.

Discovered on 23 September 2025 by our own fossil hunters, Alister and Alison, this specimen has been carefully cleaned, prepped, and treated by Alison to ensure both stability and natural beauty. As with all our fossils, this piece comes with a Certificate of Authenticity, guaranteeing that it is a 100% genuine specimen.

Geological Context and Age

This Tragophylloceras ammonite originates from the Lower Jurassic, specifically the Lower Lias sequence that dates to approximately 200 million years ago. The Green Ammonite Beds at Stonebarrow Cliff are part of the Charmouth Mudstone Formation, which represents a shallow marine depositional environment where sedimentation preserved a rich diversity of marine life.

These nodules often preserve ammonites in exquisite detail. When split, they reveal the internal chambered structure of the ammonite, offering both scientific value and striking natural beauty. The specimen reflects the conditions of early Jurassic seas that covered what is now southern England, providing an authentic glimpse into the ancient world.

Species Information – Tragophylloceras

Tragophylloceras belongs to the Ammonitida, an order of extinct marine molluscs within the subclass Ammonoidea. It is recognised within the superfamily Psiloceratoidea and family Eoderoceratidae. These ammonites are known for their moderately involute shells with distinctive ribbing and suture patterns that differentiate them from closely related genera.

In terms of morphology, Tragophylloceras is characterised by its coiled, planispiral shell, with whorls that are moderately compressed. Ribbing is generally strong, giving the fossil a bold appearance once prepped and revealed in the rock matrix. Its evolutionary significance lies in its role as a marker genus within Lower Jurassic biostratigraphy, often helping palaeontologists to refine the dating of the Lias sequences.

Scientific and Collector Appeal

Specimens of Tragophylloceras from the Green Ammonite Beds are highly sought after by collectors due to their classic locality and exceptional preservation. The nodules split naturally along bedding planes, exposing the ammonite in a way that highlights both aesthetic and scientific detail. This particular piece is a superb example, carefully prepared to reveal the ammonite’s features while preserving its integrity.

Collectors value Tragophylloceras not only for its striking appearance but also for its importance in understanding the Lower Jurassic seas. Fossils from Charmouth and Lyme Regis were first studied during the pioneering days of palaeontology in the 19th century, with contributions from figures such as Mary Anning. Today, the locality remains a vital resource for both science and education.

A Unique Fossil for Your Collection

This Tragophylloceras split nodule represents more than just a fossil – it is a piece of natural history that has endured for 200 million years beneath the cliffs of the Jurassic Coast. Each fossil is unique, with subtle variations in preservation, colour, and mineralisation that make it a one-of-a-kind specimen.

Whether you are a serious collector, a geology enthusiast, or searching for a remarkable natural gift, this ammonite offers both scientific authenticity and natural beauty. With its clear provenance, expert preparation, and included Certificate of Authenticity, it is a specimen that will stand out in any collection.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
