Description: | A well preserved fossil crinoid sp. stem (51mm x 13mm x 11mm). It is pale brown in colour and covered with a pale brown fine grained matrix particularly in between individual ossicles. The two end ossicles display the radiating structure. The one end of the stem appears to have been flattened. The number 1B has been written on in black ink. This indicates that this specimen was collected from Steven Birchs locality 1B (grid ref SO 9370 9220). This is from the Much Wenlock Limestone Formation, Nodular Member. This is Silurian in age and date at c425my. Collected from the Wrens Nest, Dudley, West Midlands. AR
