Large plant-eating dinosaurs are usually presumed to have been strictly herbivorous,
because their derived teeth and jaws were capable of processing fibrous plant foods. This …

Rare assemblages of woody coprolites from different strata of the Two Medicine Formation
provide surprising perspectives on the feeding behavior of Late Cretaceous ornithischian …

Herbivorous dinosaurs were abundant, species-rich components of Late Triassic–
Cretaceous terrestrial ecosystems. Obligate high-fiber herbivory evolved independently on …

Interpreting key ecological parameters, such as diet, of extinct organisms without the benefit
of direct observation or explicit fossil evidence poses a formidable challenge for …

Particle size reduction is a primary means of improving efficiency in herbivores. The mode of
food particle size reduction is one of the main differences between herbivorous birds …

Tyrannosaurids were large carnivorous dinosaurs that underwent major changes in skull
robusticity and body proportions as they grew, suggesting that they occupied different …

Summary The importance of adaptation [1–4] versus organizational constraints [5–7] in
shaping common macroevolutionary trends remains unclear [8]. The fossil record is key to …

For most of their existence, herbivorous dinosaurs fed on a gymnospermdominated flora.
Starting from a simple reptilian herbivory, ornithischian dinosaurs evolved complex chewing …

Ornithopod dinosaurs evolved numerous craniodental innovations related to herbivory.
Nonetheless, the relationship between occlusion, tooth wear rate, and tooth replacement …

Preserved indicators of diet are extremely rare in the fossil record; even more so is
unequivocal direct evidence for predator–prey relationships. Here, we report on a unique …
