Description: | A fossil tabulate coral identified as Halysites catenularius. The coral produces a chain like structure featuring individual corallites measuring up to1mm each. These corallites are linked by thin cell walls. The side of the specimen displays the individual corals which form vertical lines. The matrix is made up of a pale brown fine grained mud. This has infilled the centre of the corallites. Within the matrix are other secondary fossils including a very well preserved brachiopod identified as Atrypa reticularis (11mm x 11mm x 2mm). Other fragments include bryozoan, crinoid ossicles, other brachiopods and trilobite fragments. On the underside of the specimen is a large mat-like bryozoa (41mm x 40mm). Some iron oxide staining is visible on the side of the specimen. On the side by the Atrypa brachiopod is a thin (8mm) vein of fibrous calcite. AR/CB 17/05/2010
