Description
Original diagnosis after Underwood & Schlögl, 2013 [18090]: Teeth minute, rarely exceeding 1 mm high, with a single cusp overlying an irregular to bilobed root. Weak heterodonty other than compressed symphyseal teeth. Cusp slender, over three time as long as wide, straight or faintly curved. Cusp faces strongly convex with very well developed cutting edge bearing weak and very irregular serrations. Labial face of cusp with well developed granulae or irregular granulate ridges. Flared collar at base of cusp with fine pitted ornament. Root rather irregular with two lobes present to a greater or lesser degree. Basal face of root with irregular foramina or often incompletely closed over resulting in single very large basal foramen.
