Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| I. Koretsky et al. 2014 | Lower premolars p1 and p2 double-rooted, placed parallel
11 to tooth row axis; protoconid on p2 triangular; diastemata present; metaconid and basal cingulum weakly developed. Deltoid crest of humerus terminates in middle of diaphysis, its proximal part averted in dorsal direction; distal epiphysis considerably inflated compared to proximal epiphysis; lesser tubercle located higher than proximal end of deltoid crest and head; index of head’s height (ratio of head width/head height ) near 100 %; supracondylar crest strongly developed. Height of femoral greater trochanter slightly exceeds that of head; its distal end narrower than its proximal end; head very small compared with the otherwise massive bone and seated on narrow neck; minimal width of diaphysis located in proximal part of bone between neck and distal part of greater trochanter; distal end of femur 1.4– 1.5 times broader than proximal end; condyles widely separated; maximal distance between epicondyles about or more than 70 % of bone’s length. |
