Description: | A very well preserved fossil Halysites catenularia tabulate coral. It is pale grey in colour and the same colour as the fine grained matrix. The typical chain like structure of Halysites can be seen very. This structure is made up of the individual corallites which can be seen . They measure ~1mm each. Each corallite is joined to the one next to it by the thin cell walls. The chain like structure froms the cross sectional part of the specimen (60mm x 45mm x 23mm). The cell walls can clearly be seen with their elongate shape on the base of the specimen. Also on the base is a thin band (8mm x 30mm) of pink calcite. There is a secondary bryozoa fossil growing on the base which has trapped the fine grained matrix (15mm x 10m). On the side of the specimen in black ink is the number 1 A/B. This indicates that this was collected from Steven Birchs locality 1 A/B (grid ref SO 9370 9220). This specimen is from the Much Wenlock Limestone Formation, Nodular Member. This is Silurian in age and dates at c425my. This specimen was collected from the Wrens Nest, Dudley, West Midlands. AR
