Description
Original diagnosis after Ginter, Hairapetian & Klug, 2002 [3140]: Phoebodont sharks with extremely long, lingually extended tooth-bases. Near the crown, the lateral rims of the base run parallel to each other. A minute, circular button, occupying no more than one third of the base width, occurs in this region. Further lingually, the base becomes wider and its lingual/lateral ends turn slightly upwards to form distinct horns. The lingual/median part of the base is depressed; a secondary swelling and a lingual tip may occur in the axial part of the depression. The upper main basal canal opening is located at the labial end of the depression, close to the button, or slightly more lingually. The basal opening is situated in the lingual part of an elongated basal concavity. The concavity is rimmed labially by a short and thin, arcuate labio-basal projection.
