The discovery of three pairs of cochliodont tooth plates that appear to have belonged to the same fish makes it possible to describe the complete dentition of a Carboniferous chondrichthyan hitherto described from isolated dental elements only. Reconstructed from these tooth plates found in a marine deposit, the dentition consists of one pair of elongated palatal plates that occludes with two pair of plates on the lower jaw. The palatal plates were originally described as Sandalodus; the large triangular mandibular tooth plates as Deltodus. These tooth plates, with a smaller pair from the front of the lower jaw earlier assigned to Orthopleurodus, are synonymized as Deltodus angularis.
