Fig 1.
Holotype (UWBM 89090) specimen for Babibasiliscus alxi nov. taxon.
Photographs in (A) right lateral, (B) dorsal, and (C) ventral views. Digital reconstructions derived from HRXCT in (D) left lateral view and (E) transverse section. The vertical red line in (D) indicates the plane of section in (E).
Fig 2.
Comparison of the nasal and prefrontal regions of (A) Babibasiliscus alxi nov. taxon (UWBM 89090)and (B) Corytophanes hernandezi (AMNH R 147880) in dorsal view.

Right antorbital region of Babibasiliscus alxi nov. taxon (UWBM 89090) in dorsolateral view.
Fig 4.
Transverse sections through the (A) orbital region and (B) preorbital region of Babibasiliscus alxi nov. taxon (UWBM 89090) illustrating details of bones and their contacts.
Fig 5.
Photographs (A-C) and line drawings (D-F) of the skulls of selected corytophanid species in left lateral view.
(A) Corytophanes cristatus (AMNH R 16390), (B) Laemanctus serratus (photograph; AMNH R 44982), (C) Basiliscus vittatus (AMNH R 147832), (D) Laemanctus serratus (line drawing), (E) Geiseltaliellus maarius, and (F) Babibasiliscus alxi taxon nov. (UWBM 89090). Note that it is unclear whether Babibasiliscus alxi taxon nov. had a parietal crest. Reconstructed areas are represented as semi-opaque areas and/or dotted lines. Scale bars equal 10mm.

Phylogenetic hypothesis of Iguanomorpha based on the current analysis.
This is the Adam’s consensus of 98 trees. Suzanniwana patriciana and Aciprion formosum are the taxa with the most volatile positions within this analysis.
