The specimen does not have any calyx plates, but appears to have ridges on the upper part of the calyx. The top of the specimen has been repaired with light brown resin, and has a branch-like bryozoa attached. The calyx has a bit of sawn pale brown matrix cemented to the top with the number 1A written in black ink. This indicates that this specimen was collected from Steven Birchs locality 1A (GR SO 9370 9220) which is within the Much Wenlock Limestone Formation, Nodular Member. This specimen was collected from the Wrens Nest, Dudley, West Midlands. CB
