The undersurface of a sandy bed showing in strong positive relief the infills of what were originally underlying cavities. Over the surface of the block there are numerous pod like infills, about 7mm long, made by resting bivalves, Pelycypodichus, (Lockeia). There is also a large five-rayed impression of a starfish, Asteriacites, with coarse, cruziana-like striations along each arm formed by the digging action of the tube feet.
