English: FIGURE 7. Selected cross sections from 3D model of the articulated cranium and lower jaws of Crassigyrinus scoticus. Individual bones shown in different colors. Lower case letters in A indicate corresponding slices. A, 3D model of skull in dorsolateral oblique view; B, 3D model of the basioccipital in ventral view (anterior is upwards) with corresponding transverse slice from corresponding original CT data of NHMUK VP R10000 demonstrating bone porosity (slice is not shown in A because the basioccipital is internal to the facial and skull roof bones); C, transverse slice through reconstructed cranium immediately anterior to the basal articulation; D, transverse slice through reconstructed cranium at the approximate midpoint of the main body of the pterygoid; E, transverse slice through reconstructed lower jaw showing contact between the surangular (green) and articular (yellow) with transverse slice from the similar region of original CT data of NHMUK VP R10000 demonstrating articular and surrounding contacts; F, transverse slice through reconstructed cranium through the palatine; G, transverse slice through the anterior end of the reconstructed lower jaw showing cross-sectional geometry of the anterior splenial. Not to scale.
