Top: Lateral view, specimens scaled to approximately the same cranial height. Note the tall malar region (black bar), prominent maxillary ridges and deep maxillary fossae (white arrows) in UW 88–886 and P. angusticeps compared with P. izodi. Bottom: Dorsal view, specimens scaled to approximately the same cranial width. Note the longer, narrower muzzle in P. angusticeps compared to P. izodi, and again the prominent maxillary ridges and deep maxillary fossae in UW 88–886 and P. angusticeps compared with P. izodi.
