Its is slightly fractured and the edges are covered in matrix. The second bivalve with a single original label attached is Plagiostoma sp.. This specimen has an ammonite on the surface, well defined ribs and growth lines. The single valve has a flat side and a rounded opposite side, with a missing edge. The third specimen is a Pleuroceras sp. ammonite, with some matrix on its surface. The belemnite specimen is a Passaloteuthis sp. which appears broken into two sections (41mm and 24mm) narrowing towards one end. It has a smooth surface with a cross-section view in the crystalline interior. The matrix is a brown colour composed of medium grained sand. The matrix also contains other shelly fragments.
