Description
Original diagnosis after Duffin & Milàn, 2017 [25854]: Myriacanthid genus known from isolated palatine (upper posterior) and mandibular (lower) tooth plates only. The palatine tooth plate is covered with pleromin (no tritoral areas) and possesses a prominent central ridge which expands lingually, and a weak ridge flanking the labial margin. The mandibular tooth plate is elongate mesio-distally; the occlusal surface is covered with pleromin (no tritoral areas) and transected by a convex central ridge running from the labial angle to the lingual angle, giving way laterally to flattened labial and lingual fields.
