Summary
| Description | Hypotheses for jaw movement during tooth-to-tooth occlusion in Heterodontosaurus tucki. Jaw movements (arrows) to account for shearing wear facets during isognathous occlusion (from Crompton and Attridge 1986) A Dorsomedial movement of the lower jaws against stable maxillary tooth rows B Dorsal movement of the lower jaws with lateral flaring of the maxillary tooth rows C Medial rotation of the dentaries pivoting anteriorly at the predentary-dentary joint. | |||
