In the dusk of the Mesozoic, advanced duck-billed dinosaurs (Hadrosauridae) were so
successful that they likely outcompeted other herbivores, contributing to declines in dinosaur …

Here we report an unequivocal arboreal coelurosaur, Epidendrosaurus ningchengensis
gen. et sp. nov. This juvenile coelurosaur's third manual digit is extremely elongated …

Protoporphyrin (PP) and biliverdin (BV) give rise to the enormous diversity in avian egg
coloration. Egg color serves several ecological purposes, including post-mating signaling …

Alvarezsauria is a group of early-branching maniraptoran theropods that are distributed
globally from the Late Jurassic to the latest Cretaceous. Despite recent increases in the …

Abstract The Early Cretaceous Jehol dromaeosaurids are taxonomically and
morphologically diverse, and one of them, Microraptor zhaoianus, has been suggested to be …

Paleontological information and information about living vertebrate predators are combined
to enhance speculation about the feeding ecology of carnosaurs. Like young crocodilians …

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

Non-avian theropod dinosaurs attained large body sizes, monopolising terrestrial apex
predator niches in the Jurassic–Cretaceous. From the Middle Jurassic onwards …

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

Early members of the dinosaur–pterosaur clade Ornithodira are very rare in the fossil record,
obscuring our understanding of the origins of this important group. Here, we describe an …
