Description: | A well preserved complete circoconarida Cornulites sepularius measuring (63mm x 19mm). The specimen narrows towards the base forming a conical shape slightly curved at the base, with well defined horzontal growth lines along the length of the fossil. The specimen is significantly covered in a pale brown micrite cement containing crinoid stem sections and small brachiopods. The widest end (top) has been broken revealing a dark grey, fine grained crystalline structure. This specimen was from the Silurian Much Wenlock Limestone Formation, Nodular Member which is approximately 425my. The surface has an undulating surface possibly due to secondary organic bore holes.
