Description
Original diagnosis after Siverson, Lindgren, Newbrey, Cederström & Cook, 2015 [22014]: Robust anterior teeth with thick, moderately tall, triangular cusp; either straight, somewhat distally inclined or very slightly curved/recurved. Root asymmetrically subtriangular in basal view in anterior teeth with one lobe considerably broader than other lobe. Cusp very broad and triangular in anteriorly situated lateroposterior teeth with flat labial face of cusp in profile view. Cusp narrower, generally more upright in lateroposterior teeth with slightly lingually curved cusp in profile view. Root markedly asymmetrical in basal view in anteriorly situated upper lateroposterior teeth with distal lobe narrower than mesial lobe in all but one tooth type. Latter, distinct tooth type with apically curved cusp and sub-rectangular root in basal view, with root-lobe on same side of vertical mid-line of tooth as apex of cusp more compressed than other lobe.
