Description
Original diagnose after Duffin & Batchelor, 2025 [34256]: Species known from isolated teeth characterised by the following combination of characters: the root is slightly wider than the crown mesiodistally; the central cusp is relatively low and squat; the apron extends to the base of the tooth and usually has a wide, squared, narrow terminus and parallel walls, although in some cases these may be rounded and tapering respectively. The cutting edges are well-developed. The mesial and distal heels are deep and horizontal to minimally downturned. A horizontal ridge runs the labial length of the crown just above the crown/root junction, with short vertical ridges on the mesial and distal heels basally. The crests of the mesial and distal heels are usually linear, entire and little inflated. Tiny serrations and incipient crenulations may be developed in some specimens.
