Diagnosis
ReferenceDiagnosis
S. J. Rahmat and I. Koretsky 2016Diagnosis for skull (holotype), mandibles and teeth was
published by Koretsky and Rahmat (2015). Humeral head rounded, flattened, compressed craniocaudally (similar to Monachinae); ratio of head’s width to height is 0.94 (similar to Monachinae); intertubercular groove deep, short, narrow (similar to Monachinae, in contrast to Cystophorinae and Phocinae); greater tubercle oval, well developed, slightly elevated above head; lesser tubercle oval, flattened, almost same level as head (in contrast to Monachinae); proximal part of deltoid crest located slightly higher than head and lesser tubercle; deltoid crest strongly developed, short, terminates near middle of diaphysis; greatest width of deltoid crest located in middle (similar to Cystophorinae, in contrast to Phocinae); deltoid tuberosity small, located in middle of deltoid crest (similar to Cystophorinae); medial epicondyle flattened, extends to middle of coronoid fossa (in contrast to Cystophorinae); coronoid fossa oval, shallow (similar to Cystophorinae); entepicondylar foramen large, oval, with wide bridge over it; middle of humeral trochlear crest located at level of coronoid fossa (similar to Phocinae).
Ulna’s olecranon large, curves caudally; olecranon tuberosity prominent; trochlear notch flattened, well developed; radial notch very pronounced, concave in shape; coronoid process round, flat, shallow; anconeal process very large, wide, protrudes; styloid process well developed, oval; distal part of ulna flattened; upper part of trochlear notch wider than lower.
Innominate’s ilium thin, excavated on ventral surface (similar to Lobodontini, in contrast to Cystophorinae, Monachinae and especially Phocinae); iliac tuberosity flattened, small, averted; iliac crest thin, well outlined, not averted (similar to Monachinae); iliac spine thin (similar to Monachinae, in contrast to Cystophorinae and Phocinae); acetabulum deep, with pronounced rim.
Femoral head small, round, seated on distinct lip on short and wide neck (similar to Phocinae); greater trochanter extends above head; proximal and distal parts of greater trochanter approximately of equal width (similar to some Phocinae); trochanteric fossa oval, deep, with overhanging lip of medial part of greater trochanter (in contrast to Phocinae); supracondylar fossa shallow, wide, elongated; smallest width of diaphysis shifted towards proximal end of bone (similar to Monachinae and Cystophorinae); lateral condyle significantly larger than medial (in contrast to Cystophorinae); ratio between proximal and distal epiphyses 1.04 (in contrast to Cystophorinae, Monachinae and Phocinae).
Referred specimens. In addition to the holotype (skull), the following specimens were found: scapula: SNMZ 14537 (R., proximal end); humerus: SNMZ 25507 (L.); radius: SNMZ 25505 (proximal end); ulna: SNMZ 25504 (L.); innominate: SNMZ 14543 (L.); femur: SNMZ 14544 (R.); tibia and fibula: SNMZ 14545 (L., proximal half).
