. Bulletin. Natural history; Natuurlijke historie. MAMMALIAN ORDER TAENIODONTA 107. Fig. 35. The left scapula of Stylinodon mirus, YPM 11096. a) Lateral view, b) Medial view. Abbreviations: a = acromion; ax = axillary border; c = coracoid process; gf = glenoid fossa; is = infraspinous fossa; m = metacromion; n = neck; sb = subscapular notch; sp = spine; ss = supraspinous fossa; v = vertebral border. Scale is 4 cm long. The semilunar notch is broad mediolaterally and shallow, as is the radial notch, which is almost flat. The radial notch is positioned well dorsad (anteriorly) rather than more laterally. The coronoid process is relatively low, whereas the olecranon process (sensu Greene 1935) is raised slightly higher above the shaft. The distal end is slightly expanded and bears a well-developed, posteriorly-set styloid pro- cess. This bears an anterodistally facing facet that is very slightly concave dor- soventrally for articulation with the cuneiform, and medially a triangular-shaped facet, which is slightly convex in both directions, for articulation with the pisi- form. Radius The radius of Stylinodon (Fig. 37; PI. 55: figs. 3, 4) is similar to and about the same length as that of Ectoganus, but much more robust. The proximal head is oval in shape (seen proximally) with the long axis elongated mediolaterally. The posterior (ventral) facet, which articulates with the radial notch of the ulna, is rather flat and of moderate size. The articular facet for the capitulum of the humerus is smoothly concave in both directions. The neck is stout and there is no distinct tuberosity. Distally, the shaft of the radius is expanded both mediolat- erally and dorsoventrally. The styloid process is broad, blunt and positioned.
