ABSTRACT
Two of the greatest drivers of organismal evolution are eating and reproduction. We know, of course, that dinosaurs had to eat, but how can we know what they ate, specifically? This chapter covers the advantages and disadvantages of herbivory and carnivory before getting into the direct and indirect evidence for dinosaur diets. Skeletal and dental adaptations provide indirect evidence for particular diets. The indirect evidence for dinosaur diet discussed includes tooth morphology, jaw shape, jaw musculature, jaw articulation, bony correlates of cheeks, skeletal anatomy, and feces (coprolites). Some fossil evidence also provides direct evidence of dinosaur diets. Direct evidence discussed includes things like tooth marks, embedded teeth, and stomach contacts.
