Lateral teeth 3 + 1 + 6-7, elongate, each with triangular and asymmetric cusps: larger primary cusp long and wide; 3 inner and 6-7 outer, smaller pointed denticles at the sides. Marginal teeth elongated, cusps subequal; inner marginal teeth with ~17 cusps on outer 1/3 of teeth, outer marginal teeth with ~6-7 cusps on inner distal 1/3.
