Figures

FIG. 3. Plantar views of left forefoot (manus) and wrist of Marmosops pinheiroi (A, AMNH 267346) and M. bishopi (B, MUSM 23801) illustrating different morphologies of the lateral carpal tubercle (lct), which is spoon shaped in adult males of M. pinheiroi and bladelike (laterally compressed) in adult males of M. bishopi.

FIG. 8. Lingual view of the first two lower right molars (m1 and m2) of Marmosops bishopi (A, AMNH 276697) and M. carri (B, AMNH 234953) illustrating taxonomic differences in the cusp height. In M. bishopi the entoconid (encd) of m1 is shorter than the adjacent paraconid (pacd) of m2, whereas these cusps are subequal in height in M. carri.

FIG. 21. Dorsal and ventral views of skulls of Marmosops bishopi (left, MUSM 23803) and M. juninensis (right, AMNH 230016). All views about ×3.

FIG. 22. Lateral views of skulls and mandibles of Marmosops bishopi (above, MUSM 23803) and M. juninensis (below, AMNH 230016). All views about ×3.

FIG. 23. Lateral view of zygomatic arch of Marmosops bishopi (A, MUSM 23803) and M. juninensis (B, AMNH 230016) illustrating species differences in the extent of dorsal overlap between the zygomatic process of the squamosal (zps) and the jugal (jug).
