Fig. 11. Marmosops incanus (MVZ 182768) and Metachirus nudicaudatus (AMNH 267009), right os coxae with sacral vertebrae in lateral view. In the sacral vertebrae of Marmosops incanus the spinous process is present only in S1 (ch. 40[0]), whereas in Metachirus the process is present in both vertebrae (ch. 40[1]), and the S1 spinous process is taller than the S2 spinous process (ch. 41[1]). In Metachirus, the acetabulum (ac) is close, deep, and with the dorsal part laterally extended (ch. 83[1]), and the iliac wing (iw) forms a large blade (ch. 84[1]). Scale bars: 10 mm.
