Description: | A death assemblage of the fossil brachiopod Sphaerirynchia wilsoni (65mm x 61mm x 23mm). In total there are five Sphaerirynchia wilsoni brachiopods within the specimen (19mm x 18mm x 22mm) (15mm x 16mm x 21) (19mm x 12mm x 16mm) (19mm x 16mm x 17mm) (12mm x 11mm x 5mm). These are all dark grey in colour and have been poorly preserved, there are some that are incomplete. They are almost completley covered in the limestone matrix. The limestone has a muddy matriz therefore it is known as a biomicrite limestone. Within the matrix there are small fossil fragments of brachiopods and crinoid ossicles. The one corner of the limestone has been broken off and then repaired using an orange coloured resin/glue. On the bottom of the specimen written in black ink is the number 11. This indicates that this was collected from Steven Birchs locality 11 (grid ref SO 9380 9160). This was from the Coalbrookdale Formation. This is Silurian dating at c425my and was collected from the Wrens Nest, Dudley, West Midlands. AR
