Figure 5 in Unusual morphology in the mid-Cretaceous lizard Oculudentavis
Figure 5. Phylogenetic trees showing the position of Oculudentavis (A) Phylogenetic tree showing the position of Oculudentavis usingan amniote dataset;6 (B) photograph of the holotypeof O. naga; (C) simplified phylogenetic tree showing the position of Oculudentavis using a squamate dataset7 combined with a molecular dataset15 treating some morphological characters as ordered; (D) simplified phylogenetic tree showing the position of Oculudentavis using the same dataset as in (C) but with all characters unordered; (E) simplified phylogenetic tree showing the position of Oculudentavis using the same dataset as (C) but removing molecular data. In (C)–(E), crown groups were collapsed and are represented by silhouettes. Sphenodon punctatus, Anelytropsis papillosus (Dibamidae), Sphaerodactylus klauberi (Gekkota), Smaug giganteus (Cordylidae), Xantusia vigilis (Xantusiidae), Tribolonotus gracilis (Scincidae), Bachia flavescens (Lacertoidea), Lacerta bilineata (Lacertoidea), Blanus cinereous (Amphisbaenia), Varanus komodoensis (Anguimorpha), Physignathus cocincinus (Iguania), and Ophiophagus hannah (Serpentes) are shown. Node values indicate Bremer support; nodes with no support were recovered in the implied weights analyses. See also Data S1.
Figure 3 in Unusual morphology in the mid-Cretaceous lizard Oculudentavis
Figure 3. Comparison of the two specimens of Oculudentavis, details of the lacrimal and dentary Right side view of the orbit showing the ring-like lacrimal bone (salmon color) in situ in (A) O. naga and (B) O. khaungraae (orbit view here is posterolateral to show the orbital elements more clearly). Dorsolingual view of the dentary in (C) O. naga and (D) O. khaungraae is shown. Scale bar represents 1 mm.
Figure 6 in Unusual morphology in the mid-Cretaceous lizard Oculudentavis
Figure 6. Heatmaps displaying the possible degree of deformation in Oculudentavis species O. khaungraae HPG-15-3 (Aand B) and O. naga GRS-Ref-28627 (C and D). The shape variation (degree of deformation) between the original and retrodeformed 3D surface is color coded, with yellow and dark blue representing no deformation and high deformation, respectively. Heatmaps indicating the amount of retrodeformation provide a good visual aid to display the regions where a specimen would have been deformed and what its overall shape would have looked like prior to deformation. All changes are based on observed distortions in the specimens themselves. See also Data S1.

Diptera associated with the lizard skeleton were identified as Phoridae, Platypezidae, Ceratopogonidae, or Brachycera (Empidoidea). See also Figures S1–S7 and Data S1.
