Description
Original diagnosis after Hodnett & Elliott, 2018 [26883]: A small diplodoselachian xenacanth with tall, near erect cusps. All cusps are smooth, lacking verticle cristae, with a slight mesial incline. Lateral and distal cusps labiolingually compressed with un-serrated carina. Median cusp evenly spaced from the lateral cusps, labiolingually rounded, and half the height of the lateral and distal cusps. Tooth base ovate; oral-aborally compressed, orolingual button near circular with a lingual shaft. Basolabial projection small and elliptical. Kidney-shaped aboral depression with four large foramina.
