This fossilised segment is from the Thalassina anomale, or mud lobster. They are so named due to their habitation in burrows and as such are usually fossilised with surrounding sediment.  As a crustacean they have an exoskeleton which is shed at various stages of growth. It is this exoskeleton shell that fossilises well and it is rare to find whole specimens. The Thalassina anomale still exists as a living genus and they currently can be found off the coast of the Asian mainland, Southeast Asia and down to most of Australia’s north coast. Records of fossil specimens go as far back as the Miocene period.
