Protarchaeopteryx (meaning "before

theropod dinosaur from China.[1] Known from the Jianshangou bed of the Yixian Formation, it lived during the early Aptian age of the Early Cretaceous, approximately 124.6 million years ago.[2] It was probably a herbivore or omnivore, although its hands were very similar to those of small carnivorous dinosaurs. It appears to be one of the most basal members of the Oviraptorosauria, closely related to Incisivosaurus,[3][4] or a taxon slightly less closely related to birds than oviraptorosaurs were.[5][6]

Description

Protarchaeopteryx size, compared to a human
Skeletal reconstruction of known material

The holotype and only known specimen of Protarchaeopteryx is NGMC 2125, a partial skeleton.[7]

Protarchaeopteryx had long legs, and could have been a quick runner. It had well-developed, vaned feathers extended from a relatively short tail; the hands were long and slender, and had three fingers with sharp, curved claws. Its bones were hollow and bird-like, and it possessed a

arboreal lifestyle, jumping from tree limbs and using its forelimbs for a form of parachuting.[11]
