Description: | A complete dark grey coloured Atrypa sp. brachiopod (10mm x 9mm x 6mm). In between the ribs there is a pale brown fine grained matrix. The majority of the growth lines are fine and smooth but there are a few on each valve which are clearly visible. The beak is very prominant. In places there is an iron oxide staining. Near the beak there is a small area (1mm x 1mm) where some of the ribs are missing. This has been altered by iron oxide. This specimen is Silurian in age and dates at c425my. Collected from the Wrens Nest, Dudley, West Midlands. AR
