Description: | A complete poorly preserved gastropod called Poleumita sp. (43mm x 36mm x 21mm). Only a small amount of the dark grey fossil is visible this is because it is buried beneath a pale brown fine grained micritic matrix.The coiled shape can be seen with the matrix picking out the growth lines and highlighting them. There is a lot of red/orange iron oxide staining. The outer whorl is the widest. The bottom part of the specimen is very rounded in shape and formed by the matrix. This is heavily stained by iron oxide. Parts of the fossil have been fractured during deposition. There are some secondary fossils within the matrix underneath these are fragmented. They include bryozoan, brachiopods and crinoid ossicles. This is Silurian dating at c425my and was collected from the Wrens Nest, Dudley, West Midlands. AR
