Description
Original diagnosis after Hairapetian & Ginter, 2009 [3146]: As for genus: Crushing type tooth-crowns with a central, swelling cusp and a diagnostic median lingual projection. the cusps are fused, only two lateral ends are elevated. a few strong cristae run irregularly on the lingual side of the crown; the labial side possesses fewer cristae, or is almost smooth. a row of labial cusplets may or may not occur at the crown/base interface. the base is extended lingually and perforated with numerous canals or grooves. the linguo-aboral side of the base lacks foramina.
