Rhombocorniculum is a species of small shelly fossil comprising twisted ornamented cones. It has been described from the Comley Limestone and elsewhere. R. cancellatum straddles the Atdabanian/Botomian boundary.[1] The structure of its inner layer suggests that its phosphatic fibres formed within a flexible organic matrix.[3]
