Packstone

Hand Specimen. Pale yellow-grey mudstone containing the fossil remains of a small arthropod with a segmented exoskeleton. The rock is banded and shows some surface discolouration due to weathering. Rock fizzes with acid, so contains carbonate. This is a soft, though well consolidated limestone (the surface has been scratched).
