Description: | A pygidium and base of thorax from Encrinurus variolaris measuring (17mm x 16mm x 7mm) which is dark grey in colour. The specimen is preserved in a pale brown micrite matrix (30mm x 23mm x 16mm) containing shelly fragments. The pygidium has well preserved possible spine bases and the thorasic segments have small fractures along them. Part of the matrix near some thorasic segments has been repaired with light brown resin. The top of the thorax and pygidium has a white colouration due to weathering. This specimen was from the Much Wenlock Limestone Formation, Nodular Member. This was collected from the Wrens Nest, Dudley, West Midlands. CB
