Figure 15 in The Lower Jurassic ornithischian dinosaur Heterodontosaurus tucki Crompton & Charig, 1962: cranial anatomy, functional morphology, taxonomy, and relationships

Figure 15. Heterodontosaurus tucki Crompton & Charig, 1962. A, reconstruction of the neurocranium in left lateral view (with surrounding bones indicated as transparent). B, outline based on (A) above with annotations to identify specific structural features. Reconstruction based on the skulls of SAM-PK-K337 and K1332 supplemented by stereo photographs prepared for A. W. C. in anticipation of the earlier planned publication. Notes: the suture between the lateral walls of the braincase and the floor is unclear; the sutures between the laterosphenoid, proötic and opisthotic are not discernible; the extent of the dorsal lappet that appears to project from the dorsomedial edge of the?proötic is uncertain (it remains a possibility that the 'lappet' represents an anterior extension of the supraoccipital); the details of the anatomy of the basisphenoid flange in the proximity of the trigeminal fossa are unclear – even in the original stereo pairs prepared for A. W. C. For full list of abbreviations see end of paper.
