The fossils are concentraited towards one side of the matrix, with many bryozoa, crinoid stem and brachiopod fragments One of the bryozoa fragments 10mm from one of the trilobites is branched like a tree and can be identified as Dictyopora sp. measuring 7mm long. The underside of the matrix displays a trilobite pygidium cast (5mm) and interior of a single brachiopod valve (12mm). The specimen is preserved in a light brown micrite slab (61mm x 42mm x 25mm). On the side in black ink the number 8C can be seen which indicates that this specimen is from locality 8C on Steven Birchs locality list (GR SO 9390 9160).
