Description

Rare Dimorphoplites chloris Ammonite Fossil from Folkestone, Kent

This exceptional specimen is a Dimorphoplites chloris ammonite fossil from the Aptian stage of the Early Cretaceous, approximately 125–113 million years old. Discovered within the world-famous Gault Clay Formation at Folkestone, Kent, United Kingdom, this ammonite offers a superb opportunity to own a scientifically important and beautifully preserved fossil. The exact fossil shown in the photographs is the specimen you will receive, with a 1 cm scale cube included for accurate sizing. Every specimen is accompanied by a Certificate of Authenticity, guaranteeing its provenance and genuine nature.

Geological Setting and Age

The Gault Clay Formation is a richly fossiliferous deposit laid down in a warm, shallow marine environment during the Aptian stage of the Cretaceous Period. Stretching across southern England, the Gault is renowned for its exceptional preservation of ammonites, belemnites, bivalves, gastropods, and marine vertebrate remains. Fossils from Folkestone are internationally recognised for their scientific importance, with the Gault Clay yielding classic index fossils used for precise biostratigraphic dating.

Scientific Classification

• Order: Ammonitida
• Superfamily: Deshayesitoidea
• Family: Deshayesitidae
• Genus: Dimorphoplites
• Species: Dimorphoplites chloris

This ammonite is a significant index fossil of the Aptian, making it invaluable for correlating rock layers across Europe. Its occurrence within the Gault Clay provides vital evidence for paleontologists studying faunal succession, paleoecology, and the evolution of ammonites in the Early Cretaceous seas.

Morphological Features

Dimorphoplites chloris is characterised by a moderately evolute shell with well-defined ribbing and ornamentation. Its ribs often bifurcate or branch along the flanks, producing a striking and easily recognisable pattern. The venter (outer whorl edge) is typically rounded, giving the shell a robust yet elegant appearance. These distinct features make Dimorphoplites chloris both a scientifically useful fossil and a visually appealing collector’s piece. The strong ribbing also reflects its evolutionary adaptations for life in mid-Cretaceous seas, helping the animal maintain buoyancy and stability in varying marine environments.

Paleontological and Historical Importance

Ammonites such as Dimorphoplites were nektonic predators, moving actively through the water column and feeding on smaller marine organisms. Their rapid evolutionary turnover and widespread distribution have made them some of the most valuable tools for geological dating. Specimens from the Folkestone Gault Clay are especially prized, as this locality has been a key site for fossil study since the 19th century, attracting both amateur collectors and professional paleontologists.

Collectability and Display Value

This fossil represents an authentic piece of Britain’s deep geological history and offers collectors, educators, and enthusiasts a remarkable display specimen. With its intricate ribbing and excellent preservation, Dimorphoplites chloris is not only a scientifically important ammonite but also a striking natural work of art. Whether displayed in a private collection, used for educational purposes, or gifted to a fossil enthusiast, this ammonite embodies both beauty and paleontological significance.

All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity. This carefully chosen ammonite is a unique piece of natural history from the Cretaceous seas of southern England, preserved for millions of years and now available for you to own.
