Figure 2 in Morphology and spatial constraints in a dorso-ventrally flattened skull, with a revised species description of Platyallabes tihoni (Poll, 1944)
Figure 2. Dorsal view of skull of Platyallabes tihoni (156 mm SL) (MRAC 125345–349), left series of infraorbital and suprapreopercular bones removed. Scale bar: 2 mm.
Figure 9. Schematic 3D in Morphology and spatial constraints in a dorso-ventrally flattened skull, with a revised species description of Platyallabes tihoni (Poll, 1944)
Figure 9. Schematic 3D reconstruction of the lower jaw-suspensorium articulation area. (a) Overview of the lower jaw, suspensorium and part of skull at level of articulation with suspensorium. Solid lower jaw indicates closed mouth, transparent lower jaw indicates open mouth. Black arrow shows displacement of lower jaw according to the black axis indicated at the jaw articulation. The grey arrows indicate the movements of the lower jaw halves if they were rotated along the grey axis at the articulation. (b) Detail from a postero-ventral view of the lower jaw articulation, showing the two rotation axis: black rod represents the axis which allows a proper mouth opening, grey rod represents the axis of rotation which has shifted together with the suspensorium. Rotation along the black axis results in the medial position of the retroarticular process; with respect to the suspensorium (transparent lower jaw indicates the closed mouth, solid lower jaw the open mouth).

Figure 1. A in The relationship between skull morphology, biting performance and foraging mode in Kalahari lacertid lizards
Figure 1. A, phylogenetic relationships among major lizard clades showing the evolution of foraging mode across squamates. The cladogram is based on Estes, de Queiroz & Gauthier (1988). B, phylogenetic relationships among the taxa included in this study. Sit-and-wait foraging (black bars) is presumed to be the basal condition for both Meroles and Pedioplanis. See text for details. The cladogram is based on Arnold (1991).
Figure 3 in The relationship between skull morphology, biting performance and foraging mode in Kalahari lacertid lizards
Figure 3. Scatterplot of snout–vent length (mm) and bite force (Newtons). Without correcting for body size differences, P. namaquensis was significantly different from all other species and P. lineoocellata was significantly different from H. lugubris. After correcting for body size, H. lugubris was significantly different from the other species. The error bars represent standard error. Hl = H. lugubris, Ms = M. suborbitalis, Pl = P. lineoocellata, Pn = P. namaquensis.
Figure 4 in The relationship between skull morphology, biting performance and foraging mode in Kalahari lacertid lizards
Figure 4. Phylogenetic mapping of skull morphology, biting performance, and foraging mode in four lacertid species. A, evolutionary transitions based on the analysis of the raw morphological and bite force data (Table 1, underlining). B, evolutionary changes based on the canonical variates analysis (boxes; Table 3) and size-corrected ANO- VAs (bars and circles; Table 1, lettering). Shared shading or symbols within the circles or boxes indicates no significant difference. The SW and WF species were expected to covary in morphology and biting performance; however, only sizecorrected head length and head width met those predictions. See text for details.
Figure 2 in The relationship between skull morphology, biting performance and foraging mode in Kalahari lacertid lizards
Figure 2. Three-dimensional plot of mean canonical scores of each lacertid species. Hl = Heliobolus lugubris (WF); Ms = Meroles suborbitalis (SW); Pl = Pedioplanis lineoocellata (SW); Pn = Pedioplanis namaquensis (WF).
