Fig. 16 in Phylogenetic Analyses Of Postcranial Skeletal Morphology In Didelphid Marsupials

Fig. 16. Lestodelphys halli (UWZM 22422) and Didelphis marsupialis (AMNH 210439), left scapula in lateral view. In Lestodelphys the supraspinous fossa (suf) width is less than one-fourth its length (ch. 54[0]) and the caudal angle (ca) is acute (ch. 57[0]), whereas in Didelphis the supraspinous fossa width is between one-fourth and one-half its length (ch. 54[1]) and the caudal angle is rounded (ch. 57[2]). Note the scapular notch (scn) in Didelphis, extended to less than half of the scapula (ch. 58[0]), whereas in Lestodelphys it is extended to the middle of the scapula (ch. 58[1]). Other abbreviations: acr, acromion; inf, infraspinous fossa, s, spine. Scale bars: 10 mm.
