Brachiopod Fossil Limestone Block Clypeus Grit Salperton Limestone Formation Jurassic Chedworth Woods Gloucestershire UK

Description

Authentic Brachiopod Fossil Block from Gloucestershire

This listing is for a genuine Brachiopod fossil limestone block from the Clypeus Grit Member of the Salperton Limestone Formation, discovered at Chedworth Woods, Gloucestershire, UK. Dating back to the Jurassic period, this specimen is around 170 million years old and represents a fascinating part of Britain’s ancient marine history. The exact fossil you see in the photographs is the one you will receive, with a 1 cm scale cube included for accurate size reference.

The specimen was collected on 05 May 2024 by our experienced team members, Alister and Alison, and has since been professionally cleaned, prepped, and treated by Alison to ensure its preservation and to highlight its natural features. As with all our fossils, this specimen is supplied with a Certificate of Authenticity, guaranteeing its provenance and 100% authenticity.

Geological Setting and Age

The fossil originates from the Clypeus Grit Member, part of the Salperton Limestone Formation, which is exposed in the Cotswold region of Gloucestershire. This formation is Middle Jurassic in age, specifically belonging to the Bathonian stage, approximately 168–166 million years ago.

The limestone deposits of this area were formed in warm, shallow marine environments, similar to modern-day tropical seas. The conditions were ideal for marine life such as brachiopods, bivalves, echinoids, and ammonites, many of which are preserved in limestone blocks like this one. The Clypeus Grit in particular is known for its fossil richness and its importance in British palaeontology.

Species Information – Brachiopods

Brachiopods are a group of marine invertebrates belonging to the phylum Brachiopoda, which flourished during the Palaeozoic and Mesozoic eras. Although they resemble clams or bivalves, brachiopods are a distinct group with a different internal structure. They are characterised by two shells (valves) of unequal size and shape, which are hinged at the rear.

These organisms lived attached to the seafloor by a stalk-like structure known as a pedicle. They were filter feeders, drawing water through their shells to capture microscopic food particles using a specialised feeding organ called a lophophore. Fossilised brachiopods provide vital information about Jurassic marine environments and remain important index fossils for correlating rock layers.

Fossil Features and Preservation

This limestone block contains well-preserved brachiopod shells, visible within the natural stone matrix. Their ribbed external morphology and convex shell form are clearly distinguishable, showcasing the classic features of Jurassic brachiopods. The fossil surfaces have been carefully prepared to enhance visibility while maintaining the integrity of the specimen.

The block format makes it an excellent display piece, as it preserves both the fossils and their geological context. The preservation of brachiopods within limestone allows for fine detail to be retained, making this a scientifically valuable and visually appealing specimen.

Collector and Educational Significance

This brachiopod fossil block is an excellent addition to any collection, whether you are a serious fossil enthusiast, a geology student, or an educator. Its clear provenance from the Salperton Limestone Formation and its Jurassic age make it a valuable specimen for study and display.

The fossil provides insight into ancient marine ecosystems and highlights the diversity of life in Jurassic seas. As a natural history specimen, it is equally suitable for private collections, museum displays, or as an educational resource for teaching about palaeontology and geology.
