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 time, Dorset lay beneath a warm, shallow marine sea rich in life, including ammonites, belemnites, fish, and marine reptiles.

The marls were deposited in a relatively quiet offshore environment where fine sediments accumulated on the seabed. Low oxygen conditions helped prevent decay and scavenging, allowing ammonite shells to fossilise in exceptional detail.

Stonebarrow Cliff and the surrounding Charmouth coastline are internationally famous for producing some of the finest ammonites in the world, making specimens from this locality highly collectible.

Fossil Species – Echioceras Ammonite

Echioceras is a distinctive genus of Early Jurassic ammonite belonging to the extinct subclass Ammonoidea, within the class Cephalopoda. These marine molluscs were close relatives of modern squid and cuttlefish and were among the dominant predators of Jurassic oceans.

Echioceras is especially well known as an important Lower Lias index fossil, frequently used in biostratigraphy to date and correlate Early Jurassic strata across Europe. Specimens are prized for their elegant coiled form and well-defined ribbing, which reflects the animal’s growth stages and hydrodynamic adaptations.

Collectors value Echioceras both for its scientific significance and its classic Jurassic ammonite appearance.

Morphology and Preservation Features

This specimen preserves the characteristic spiral shell structure typical of ammonites, often with pronounced ribbing across the whorls. The Black Ven Marls are well known for producing fossils with strong surface detail, and this piece has been carefully prepared to highlight the shell’s natural form.

The fossil has been cleaned and stabilised by Alison to ensure long-term preservation, while retaining its authentic Jurassic matrix character. Ammonites such as this make striking display fossils, instantly recognisable and highly sought after.
