Description: | An incomplete fossil trilobite called Encrinurus punctatus (45mm x 44mm x 18mm). The specimen has been poorly preserved. The trilobite is a dark brown in colour. Across the specimen there is a pale brown fine grained matrix. Small white lines can also be seen on the one side which is from the preparation of the specimen. The eyes are both pronounced however, the one eye appears to have been broken off (2mm) compared to the other (5mm). All three thorasic segments can be seen. When this particular trilobite was buried it was in its rolled up position, however only half of the specimen has been left. Tubercles can be seen on the glabella. The underside of the specimen has beemn infilled with the pale brown matrix. Here the matrix contains other fragmented fossils including bryozoa, coral, brachiopods and crinoid stems. The number 2 has also been written on the underside of the specimen in black ink. This indicates that this specimen was collected from Steven Birchs locality 2 (grid ref SO 9370 9225), which is the reef mound. This was 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
