Fig. 3. Monodelphis brevicaudata (AMNH 257203) and Lutreolina crassicaudata (AMNH 133250), partial vertebral series in lateral view. In Monodelphis, C3–C5 spinous processes are lower than the axis spinous process (ch. 19[0]). The first thoracic vertebra with tall spinous process relative to other vertebrae is placed in the T2 position in Monodelphis (ch. 24[1]), but it is in the T1 position in Lutreolina (ch 24[0]). Abbreviation: Ma, manubrium of sternum. Scale bars: 10 mm.
