Illustrations of the measurements defined in the present work on a skull of Glyptodon munizi (A–F; PIMUZ A/V 461) and selected endocranial structures on a cranium of Neosclerocalyptus pseudornatus (G–I; PIMUZ A/V 439). Cranium in lateral (A), anterior (B), dorsal (D), and ventral (E) views. Mandible in occlusal (C) and lateral (F) views. Endocranial structures are represented by an isolated and verticalized inner ear (G), an isolated braincase in dorsal view (H), and a cranium in transparency and in lateral view (I), showing the inner ear (yellow), braincase (pink), and associated neurocranial canals (red).
