Stomach contents preserved in fossil specimens provide direct evidence for the diet of
extinct animals. Such exceptional fossils remain rare for predatory non-avian dinosaurs and …

Understanding the ecological roles of pterosaurs is a challenging pursuit, but one aided by a
growing body of fossil evidence for their dietary preferences and roles as food sources for …

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 …

Reconstructing the palaeoecology of extinct tetrapods is fraught with difficulties. Fossilized
evidence of direct trophic interactions between tetrapods is rare, whether the interactions …

Predatory theropod dinosaurs can usually be identified as such by features of their jaws,
teeth, and postcrania, but different clades of these reptiles differed in their adaptations for …

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 …

The diets of ornithomimosaurian dinosaurs (Theropoda: Ornithomimosauria) have proved to
be contentious owing to a dearth of unambiguous evidence in support of carnivory, omnivory …

Birds have a highly specialized and efficient digestive system, but when this system
originated remains uncertain. Here we report six gastric pellets attributable to the recently …

Prosauropods were not scavenger‐predators, rather they were the dominant large terrestrial
herbivores during the late Triassic and early Jurassic. The herbivorous adaptations of …

Many lines of evidence have been brought to bear on the question of theropod feeding
ecology, including functional and physiological considerations, morphological constraints …
