Fossil Bryozoan Sea Floor Slab – Silurian Wenlock Limestone, Wrens Nest Dudley UK


£ 14.40

A beautifully preserved Fossil Sea Floor Slab featuring colonial bryozoans,
sourced from the Wenlock Limestone Formation and dated to the Wenlockian Stage of the Silurian period (~428–423 million years ago). This fossil originates from the iconic Wrens Nest site in Dudley, West Midlands, UK — a globally important locality and one of the UK’s most famous fossil sites.

Bryozoans, often referred to as “moss animals,” are colonial, filter-feeding marine invertebrates that flourished in Silurian reef environments. This specimen displays a dense patch of bryozoan colonies encrusting the sea floor slab, capturing the biodiversity and ecological dynamics of ancient tropical marine settings.

Fossil Type: Colonial Bryozoans (marine invertebrates)

Geological Age: Silurian – Wenlockian Stage

Formation: Wenlock Limestone Formation

Depositional Environment: The Wenlock Limestone was formed in a warm, shallow marine environment, characterised by reef systems, carbonate platforms, and high biodiversity. These conditions facilitated extensive bryozoan growth alongside corals, crinoids, brachiopods, and trilobites.

Morphological Features:


• Encrusting colonies with finely detailed zooecial structures
• Calcareous, branching, or sheet-like growth patterns
• Preserved in original sea floor matrix with natural bedding plane

Notable:


• Genuine fossil from a Site of Special Scientific Interest (SSSI)
• Rich marine fossil content from a classic British Silurian locality
• Excellent display specimen or educational aid
• Photo shows the exact item you will receive

Authenticity: All of our fossils are 100% genuine natural specimens and come with a Certificate of Authenticity. The scale in the photo shows 1cm per square or cube – please consult the image for full dimensions.

This bryozoan sea floor slab from the Silurian reef ecosystems of Dudley offers a remarkable window into early marine life and is a striking addition to any fossil collection.
