a–c, Basicranium in ventral (a), dorsal/interior (b), and caudal (c) views. d–g, Left braincase in lateral (d), internal (e), dorsal (f), and caudal (g) views. Colours: brown, braincase; yellow, nasal. Numbers correspond to autapomorphies of V. iaai: 1, the presence of paired foramina on the parasphenoid perforating the endocranial cavity; 2, the unique conformation of the temporal fossa.
