Description: | Four fairly well preserved complete fossil brachiopods of Eospirifer sp. (a & b & c & d). (a) A dark grey brachiopod (23mm x 18mm x 13mm) with fine ribs. In places the ribs are infilled with a fine grained pale brown sediment. On the brachial valve there are small patches of secondary calcite (<4mm). (b) A brown brachiopod (10mm x 8mm x 4mm) with very fine ribs. On the edges of the valves a small area of a pale brown very fine grained matrix can be seen. (c) A grey brachiopod (22mm x 16mm x 9mm). In places the ribs are infilled with a fine grained pale brown sediment. The ribs have also been flattened slightly in places. There is a partially worn off patch of old white tip-ex on the brachial valve. (d) A dark grey brachiopod (15mm x 18mm x 7mm) with fine ribs. In places the ribs are infilled with a fine grained pale brown sediment. On the brachial valve there is a small patch of secondary bryozoa (3mm x 4 mm). There is a larger patch of secondary bryozoa on the pedicle valve (7mm x 7mm). On the pedicle valve at the one end there appears to be a small dark brown secondary brachiopod (1mm). All four of these specimens are from the Much Wenlock Limestone Formation, Nodular Member. They are all Silurian in age and date at c425my. All four of these specimens were collected from the Wrens Nest, Dudley, West Midlands. AR
