Four-winged dinosaurs from China
TLDR
New evidence is provided suggesting that basal dromaeosaurid dinosaurs were four-winged animals and probably could glide, representing an intermediate stage towards the active, flapping-flight stage of proavians. Expand
The smallest known non-avian theropod dinosaur
TLDR
This is the first mature non-avian dinosaur to be found that is smaller than Archaeopteryx, and it eliminates the size disparity between the earliest birds and their closest non-Avian theropod relatives. Expand
Pterosaur diversity and faunal turnover in Cretaceous terrestrial ecosystems in China
TLDR
Two new pterosaurs that are referred to European groups previously unknown in deposits of northeastern China are reported, showing a wide range of groups including both primitive and derived forms that are not matched by any other deposit in the world. Expand
A therizinosauroid dinosaur with integumentary structures from China
TLDR
This new taxon from the Yixian Formation provides fresh evidence that therizinosauroids are nested within the coelurosaurian theropods, and supports the hypothesis that the filamentous integumentary structures may be homologous to the feathers of birds. Expand
Basal tyrannosauroids from China and evidence for protofeathers in tyrannosauroids
TLDR
A new basal tyrannosauroid from the Early Cretaceous Yixian Formation of western Liaoning, China, which is small and gracile and has relatively long arms with three-fingered hands and provides the first direct fossil evidence that Tyrannosauroids had protofeathers. Expand
An unusual long-tailed pterosaur with elongated neck from western Liaoning of China.
TLDR
A phylogenetic analysis including most non-pterodactyloid pterosaurs shows that Wukongopterus lii gen. et sp. Expand
A bizarre Jurassic maniraptoran from China with elongate ribbon-like feathers
TLDR
This finding shows that a member of the avialan lineage experimented with integumentary ornamentation as early as the Middle to Late Jurassic, and provides further evidence relating to this aspect of the transition from non-avian theropods to birds. Expand
Gut microbiome and serum metabolome alterations in obesity and after weight-loss intervention
TLDR
These findings identify previously unknown links between intestinal microbiota alterations, circulating amino acids and obesity, suggesting that it may be possible to intervene in obesity by targeting the gut microbiota. Expand
Fossilized melanosomes and the colour of Cretaceous dinosaurs and birds
TLDR
It is reported that melanosomes (colour-bearing organelles) are not only preserved in the pennaceous feathers of early birds, but also in an identical manner in integumentary filaments of non-avian dinosaurs, thus refuting recent claims that the filaments are partially decayed dermal collagen fibres. Expand
New long-tailed pterosaurs (Wukongopteridae) from western Liaoning, China.
TLDR
Two almost complete long-tailed pterosaurs from the Linglongta, Jianchang County, western Liaoning, China, are described and represent new taxa referred to the non-pterodactyloid clade Wukongopteridae, suggesting that they might have occupied slightly different ecological niches. Expand
