Description: | An incomplete rolled Acaste downingiae trilobite (18mm x 13mm x 6mm) dark greyn in colour. The specimen has an almost complete thorax although the pygidium has been disjointed and the cephalon is missing. The ribs are infilled by a pale brown fine grained matrix. On the underside of the matrix, the number 6B has been written on in black ink. This indicates that this specimen was collected from Steven Birchs locality 6B (GR SO 9370 9200) which is within the Much Wenlock Limestone Formation, Nodular Member. This specimen was collected from the Wrens Nest, Dudley, West Midlands. CB
