Preserved in a pale grey micrite matrix slab (77mm x 51mm x 14mm) with areas of iron oxide staining. The matrix contains crinoid stem sections, bryozoa (Fistulipora sp.) and stromatopora. Brachiopods include Leptaena sp. and Gypidula sp., aswell as other unidentified brachiopods. The fractured secondary fossils display the internal calcite mineralisation. The cephalon is partially covered by the matrix and the eye has been broken off. On the base of the matrix there is a broken brachiopod revealing white mineralisation. This specimen was from the Much Wenlock Limestone Formation, Nodular Member. This was collected from the Wrens Nest, Dudley, West Midlands. CB
