Dental Morphology,Digestion begins with the mechanical breakdown of food between maxillary and dentary teeth; thus, the occlusal surfaces of these teeth are maintained and modified by the operation of the masticatory system. This section describes features of ornithopod dentitions (including wear patterns) that form the basis for testing kinematic models.

Ornithopod Jaw Mechanics,1978), and Krause (1982) on mammals. Similarly, the present study is based on fossils in order to understand the mechanics of jaw motion in the diverse Mesozoic herbivores known as ornithopods. Most commonly, particularly in work on mammals, vertebrate jaw mechanisms are modeled as class III levers.

Comparative Arthrology,ent occurs between adjacent skeletal elements. Joints can be classified into two broad groups on the basis of structure, function, and growth (following Warwick and Williams 1980): fibrous or cartilaginous joints and synovial joints.
