Description 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.
