Fig. 12. Lateral views of crania and mandibles of (A) Gracilinanus emiliae and (B) Hyladelphys kalinowskii based on the same specimens as in figure 11. Prominent taxonomic differences illustrated in these views include orbital size, development of the postorbital process of the jugal, braincase shape, presence of accessory cusps on upper and lower canines, and relative reduction of the third premolar.
