Description: | A well preserved Strophonella sp. brachiopod (28mm x 23mm) which is within a pale grey fine grained matrix slab (35mm x 28mm x 12mm). The fossil is dark grey in colour. Only the one valve is visible on the specimen. The two ends of the hinge line (22mm) have been broken off. There are two small holes (1 mm x 2mm) (2mm x 2mm) in the valve, one near the beak and one towards the mouth. Very fine growth lines can be seen between the fine ribs. A small amount of matrix is cemented to the surface. The one corner of the matrix has a small patch of iron oxide on it. Within the matrix is a cross section through a brachiopod (9mm x 9mm) which is darker in colour than the surrounding matrix. There are other smaller fragments of fossils within the matrix which includes other brachiopods. This is from the Much Wenlock Limestone Formation, Nodular Member. This is Silurian, dating at c425my and was collected from the Wrens Nest, Dudley, West Midlands. AR
