Diagnosis

Reference	Diagnosis
I. Koretsky et al. 2014	Phocine of medium size similar to modern Halichoerus grypus. Deltoid crest of humerus short, narrow, and thin, terminating about 1/2 length of bone; its distal end gently broadening and somewhat overhanging the bone; lesser tubercle located slightly above head and proximal part of deltoid crest; intertubercular groove narrow and deep; medial epicondyle reaches distal end of deltoid crest; entepicondylar foramen present. Femoral greater trochanter higher than head; minimal width of shaft located in middle part of femur; epicondyles very thin.
