Description: | A fossil bivalve identified as Protocardia hillana and is fairly well preserved. The specimen is missing the lower valve and is preserved within a pale brown, coarse grained sandstone matrix with other shelly fragments. This matrix is glauconitic (green alteration mineral). The valve has prominant growth lines. These growth lines have trapped a pale matrix on the surface. The top layer of the shell is missing in the centre. Ribs are present on the one side of the specimen. Some iron oxide staining can be seen around the beak. AR/CB
