Description: | A incomplete fairly well preserved specimen of a fossil Amphistrophia sp. brachiopod (25mm x 15mm). The edge of the specimen has been buried within the pale brown fine grained matrix which makes up the slab (65mm x 49mm x 26mm) of limestone in which it is located. There are small fragments of other fossils within the matrix, these include brachiopods (6mm x 6mm & 5mm x 5mm), bryozoa (7mm x 3mm) and part of a crinoid stem (3mm x 2mm). The sides of the specimen show the fossiliferous crystalline matrix, also known as biosparite limestone. Two sides have been broken to form almost straight edges. The cross sections of dark grey fossils can be seen on these edges. On the bottom of the specimen written in black ink is the number 5. This indicates that this specimen was collected from Steven Birchs locality 5 (grid ref SO 9370 9205) which is within the Much Wenlock Limestone Formation, Nodular Member. This is Silurian dating at c425my and was collected from the Wrens Nest, Dudley, West Midlands. AR
