Original price was: £8.40.Current price is: £6.72.

Discover a rare and fascinating Fossil Sponge preserved in Flint, found within the Grey Chalk Subgroup of the Cretaceous period, from the historic coastal region of Branscombe, Dorset, UK. This specimen is 100% genuine, comes with a Certificate of Authenticity, and was discovered by our own team members, Alister and Alison, on 20 March 2025. It has been carefully cleaned, prepped, and treated by Alison, ensuring both scientific value and visual appeal.

Sponges are one of the oldest multicellular life forms on Earth, and fossil examples provide invaluable insight into early marine ecosystems. This particular fossil dates back to the Late Cretaceous, approximately 85–100 million years ago, when the region that is now Dorset was submerged under warm, shallow seas. The Grey Chalk Subgroup, part of the Upper Cretaceous sedimentary layers, is known for preserving marine fossils in flint nodules formed within chalk beds.

This beautifully preserved specimen captures the structure and texture of an ancient sponge, preserved through mineral replacement within a durable flint matrix. Fossils like this are sought after by collectors and geologists alike for their rarity and educational value.

This is a carefully selected, one-of-a-kind specimen, and the exact fossil shown in the listing photos is the one you will receive. A 1cm scale cube is included in the images for size reference—please refer to the photos for full dimensions.

Description

Fossil Identification

This genuine fossil sponge is preserved in flint from the Grey Chalk Subgroup and is identified as Cretaceous in age. The specimen is associated with Branscombe, Dorset, making it an appealing addition to collections focused on British fossils, chalk geology and the natural history of southern England

Geological Setting

The Grey Chalk Subgroup forms part of the Chalk succession deposited during the Cretaceous Period. Chalk is a sedimentary rock formed predominantly from the accumulated microscopic remains of marine organisms, while flint is a hard, silica-rich material commonly occurring within chalk sequences. This geological combination provides an informative setting for fossil collecting and demonstrates how ancient marine life can be preserved within contrasting rock materials.

Fossil Sponge Interest

Sponges are among the oldest and most widespread groups of aquatic animals, and fossil sponge remains are valued for their connection with ancient marine ecosystems. Fossilised sponge material can display attractive natural textures and structures, making specimens especially interesting to collectors of palaeontology, geology and Cretaceous marine fossils. As a display piece, this specimen offers a tangible connection to the former marine environments represented by the chalk deposits of Dorset.
