Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. J. Hooker and D. Dashzeveg 2004 | Small ancylopod, upper and lower first molar length about 8mm (see Table 1 for other measurements). Molars with relatively short upper trigon and lower talonid basins. Marked wear gradient from M1 to M3. Upper molars with essentially vertically implanted paracone and metacone, with only slightly buccally flexed centrocrista, well-developed protoloph and metaloph with weak paraconule and variably developed metaconule, parastyle not distally recurved, no mesostyle, and strong lingual cingulum around protocone. M3 ectoloph elongate compared to M1–2 and with prominent metastyle. Lower molars
with straight cristid obliqua (metalophid) whose mesial end is low, joining the back of the trigonid approximately at the midpoint between protoconid and metaconid, ectocingulid strong round hypoconid, metaconid buttress present, paracristid making angle of c. 40 degrees to tooth long axis, and twinned metaconid cusps close together. M1–2 with prominent median cuspate hypoconulid and faint remnant of entoconulid developed close to entoconid. M3 bearing well-developed hypoconulid lobe with sloping distal wall and main hypoconulid cusp buccally and subterminally situated. DP4 with large mesially protruding parastyle. |
