Description
Original diagnosis after Lebedev, 2014 [21752]: Psephodontid fish with robust upper and lower tooth plates of generalized “Psephodus” design. Growth direction of the tooth plates (linguolabial axis) perpendicular to the long axis of the jaw ramus. The squarish domelike aspect of the aboral surface of the base shows no oblique twist which is typical of Psephodus tooth plates. This tooth series presents at least two element types. “Helodus”type elements were presumably present in the upper jaw, whilst a quadrangular, almost symmetrical tooth plate might be possibly associated with the lower jaw. An indentation is present in the middle of the lingual margin of the "lower” tooth plate. “Upper” tooth plate longer than broad, the coronal part strongly overhanging the basal part of the plate.
