Description
Original diagnosis after Ginter, Hairapetian & Grigoryan, 2011 [13934]: Teeth of Lissodus with a well developed occlusal crest, smooth or rarely gently crenulated, and a prominent median cusp, directed labially. Crown smooth or with delicate, short vertical striations, moderate labial peg bearing up to two tubercles; lingual margin virtually straight in lingual view and straight to convex in oral view; horizontal longitudinal crest on both sides of the crown shoulder. base of euselachian type, rather deep, vertical or slightly directed lingually, with a concave labial side.
