Fig. 19 in Phylogenetic Analyses Of Postcranial Skeletal Morphology In Didelphid Marsupials

Fig. 19. Caluromysiops irrupta (AMNH 244364) and Marmosops parvidens (AMNH 267348), proximal portion of ulna (ul) and radius (ra) in lateral view. The olecraneon (ol) is short and wide in Marmosops (ch. 72[0]), whereas it is proportionally longer and more slender in Caluromysiops (ch. 72[1]). In both species, the longitudinal groove (lg) for Mm. anconeus and abductor pollicis longus (ch. 77[2]) is well developed. Scale bars: 5 mm.
