Neurocranial Segment,). Virtually all contacts between bones that make up the braincase indicate firm union by strongly interdigitated sutures, broad and complex joint surfaces, and/or complete fusion. As a result, these joints will not be discussed here (for further osteologic information on the ornithopod cranium, con

Introduction,ormation about their trophic position, has not been settled. Postcranially, ornithopods show specialization for bipedality in hindlimb construction and lack well-developed protective structures on their flanks, back, and tail.

Kinematic Analyses of Ornithopod Jaw Mechanisms,ossible to deduce muscle-firing sequences (recruitment of muscle action) for any set of masticatory muscles. Kinematic analyses allow modeling of complex jaw systems through manipulation of spatial relationships of the skull without making assumptions about the muscular system.
