Description

Genuine Metophioceras Ammonite Fossil from the Jurassic Coast

Offered here is a beautiful and authentic Metophioceras ammonite fossil from one of the most iconic fossil localities in the world — Monmouth Beach, Lyme Regis, Dorset, UK. Preserved within the famous Lower Lias deposits of the Early Jurassic, this specimen represents a remarkable marine creature that lived nearly 200 million years ago.

This fossil is a carefully chosen piece, with the photographs showing the exact specimen you will receive. Full sizing details can be seen clearly in the accompanying images.

This is a genuine fossil and includes a Certificate of Authenticity lifetime guarantee generic card, making it a confident purchase for collectors, educators, or anyone seeking a true piece of Earth’s prehistoric history.

Geological Setting – Lower Lias, Bucklandi Zone

This ammonite comes from the Bucklandi Zone, part of the Lower Jurassic Lower Lias Group, a sequence of fossil-rich limestones and shales exposed along the Dorset coastline.

The Bucklandi Zone is an important ammonite biozone used in Jurassic stratigraphy, dating to the earliest Sinemurian Stage. These beds are internationally famous for producing superb ammonites, marine reptiles, and other diverse fauna.

Lyme Regis and the surrounding Jurassic Coast have been studied for centuries and remain one of Europe’s greatest fossil hunting regions, providing scientifically valuable specimens such as this Metophioceras.

Fossil Type – Ammonite (Extinct Marine Cephalopod)

Metophioceras is a genus of early Jurassic ammonites, belonging to the extinct subclass Ammonoidea, relatives of modern squid and nautilus.

Scientific classification includes:

• Phylum: Mollusca
• Class: Cephalopoda
• Subclass: Ammonoidea
• Order: Ammonitida
• Family: Arietitidae

Ammonites were fast-moving marine predators that thrived in Jurassic seas, leaving behind their beautifully coiled shells as some of the most recognisable fossils on Earth.

Morphology and Notable Features of Metophioceras

Metophioceras is prized for its distinctive early Jurassic form, typically displaying:

• A tightly coiled, planispiral shell
• Strong ribbing across the whorls
• A pronounced ventral keel in many specimens
• Classic Bucklandi Zone ammonite characteristics

These fossils are highly sought after due to their excellent preservation and importance in Jurassic biostratigraphy.

Each ridge and curve of the shell reflects the growth of the animal across its lifetime, now mineralised into stone over millions of years.

Depositional Environment – Jurassic Seabed Preservation

During the Early Jurassic, Dorset lay beneath a warm, shallow marine environment teeming with life. Ammonites such as Metophioceras lived in open waters, while their shells eventually sank to the seabed after death.

Fine sediments buried these remains quickly, protecting them from scavengers and allowing mineral-rich conditions to fossilise them in exceptional detail.

The Lower Lias deposits around Lyme Regis are especially famous for preserving ammonites in high quality, making this fossil a true representative of Britain’s Jurassic marine ecosystems.
