Figure 4 in Morphological disparity in a hyperdiverse mammal clade: a new morphotype and tribe of Neotropical cricetids

Figure 4. Mandible morphology of Rhagomys: A, external view of the left hemimandible of R. longilingua (FMNH 170687): note the chin process (c) and the straight inner border (b); B, external view of the left hemimandible of R. septentrionalis (MECN 6172); C, medial view of the left hemimandible of R. septentrionalis (MECN 6172); D, dorsolateral view of the retromolar fossa in the left hemimandible of R. septentrionalis (MECN 6172); E, lingual dorsolateral view of the retromolar fossa in the left hemimandible of R. rufescens (MZUFV-CM 3706): note the elevated bony ridge (mi) forming the caudad close of the fossa. Except for A and E the pictures are three-dimensional reconstructions based on micro-CT data.
