Description: | A fairly well preserved complete fossil brachiopod called Atrypa reticularis (20mm x 19mm x 11mm). It is brown in colour. The ribs and growth lines can be clearly seen. A pale brown fine grained matrix can be seen around the edges of the valves and highlighting the ribs and growth lines. There is a small fold (4mm). Patches of orange iron oxide staining are visible. On the one valve there is a small hole (2mm) which is infilled with sediment with an iron oxide staining. This is from the Much Wenlock Limestone Formation, Nodular Member. This is Silurian in age and dates at c425my. Collected from the Wrens Nest, Dudley, West Midlands. AR
