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 …

Gut contents are extremely important for inferring trophic interactions between extinct
species. These are, however, very rare in the fossil record and it is not always possible to …

The largest specimen of the four-winged dromaeosaurid dinosaur Microraptor gui includes
preserved gut contents. Previous reports of gut contents and considerations of functional …

Direct indicators of diet and predator-prey relationships are exceedingly rare in the fossil
record [1, 2]. However, it is through such traces that we can best understand trophic …

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 …

Non-avian dinosaurs are mostly medium to large-sized animals, and to date all known
mature specimens are larger than the most primitive bird, Archaeopteryx. Here we report on …

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 …

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

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 …

The'Archaeoraptor'fossil, once proclaimed as a key intermediate between carnivorous
dinosaurs and birds but now known to be a forgery, is a chimaera formed of bird and …
