Description: | Well preserved dorsal valve from Strophonella sp. (51mm x 41mm x 10mm) and Cornulites sp. brachiopod measuring (22mm x 5mm). The specimens are preserved in a light brown micrite matrix slab (63mm x 58mm x 28mm) containing many crinoid and brachiopod fragments up to 2mm. The Strophonella sp. valve has a brozoan on the surface near the hinge line, and also on the rear of the specimen beneath the front edge. The valve is fracture diagonally across. Cemented on to the Strophonella sp valve is a Cornulites sp. near the front edge, this forms a conical shape as it narrows towards its base with a number of ribs around its circumference. A number 8B written on the rear of the matrix in black ink indicates that this specimen was collected from Steven Birchs locality 8B at the Wrens Nest, Dudley (GR SO 9390 9160) in the Coalbrookdale Formation.
