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).
