Geological Setting – Blue Lias Formation, Jurassic Coast

This fossil originates from the renowned Blue Lias Formation, dating to approximately 190–200 million years ago during the Early Jurassic. At this time, southern England lay beneath a warm, shallow sea teeming with marine life including ammonites, belemnites, fish, marine reptiles, and diverse shellfish communities.

The Blue Lias is famous for its alternating limestone and shale layers, deposited in low-energy marine environments that allowed shells and skeletal remains to become buried gently and fossilised in exceptional detail.

Monmouth Beach, situated between Lyme Regis and Charmouth, is one of the most productive fossil localities on the Jurassic Coast. Fossils from this area are highly sought after due to the historic importance of Lyme Regis in paleontology and the consistent quality of specimens preserved within these deposits.

Fossil Species – Plagiostoma Bivalve

Plagiostoma is a genus of fossil marine bivalve mollusc, belonging to the class Bivalvia, a group that includes modern clams, scallops, and oysters. During the Jurassic, bivalves like Plagiostoma were widespread in shallow marine environments, forming an essential part of the seafloor ecosystem.

Plagiostoma shells are typically characterised by their elegant curved form, strong growth lines, and distinctive hinge structure. These bivalves lived as filter feeders, drawing seawater through their shells to extract microscopic food particles.

As fossils, Jurassic bivalves provide valuable insight into ancient marine habitats, sediment conditions, and the biodiversity of Early Jurassic seas.

Preservation and Fossil Features

This specimen preserves the natural shell shape and surface detail, capturing the original form of the bivalve that lived nearly 200 million years ago. Fossilisation within the Blue Lias limestone helped maintain clarity of the growth ridges and overall morphology.

Bivalve fossils are wonderful display pieces because they represent everyday life on the Jurassic seafloor, offering collectors a more complete picture of the ecosystem beyond the more famous ammonites and marine reptiles.

This fossil is ideal for display cabinets, educational use, or as an accessible yet scientifically meaningful collector specimen from Lyme Regis.
