Exceptional dinosaur fossils show ontogenetic development of early feathers
Recent discoveries of feathered dinosaur specimens have greatly improved our understanding of the origin and early evolution of feathers, but little information is available on the ontogeneticExpand

A new feather type in a nonavian theropod and the early evolution of feathers
All described feathers in nonavian theropods are composite structures formed by multiple filaments. They closely resemble relatively advanced stages predicted by developmental models of the origin ofExpand

A bizarre Jurassic maniraptoran theropod with preserved evidence of membranous wings
The wings of birds and their closest theropod relatives share a uniform fundamental architecture, with pinnate flight feathers as the key component. Here we report a new scansoriopterygid theropod,Expand

A new arboreal haramiyid shows the diversity of crown mammals in the Jurassic period
A major unsolved problem in mammalian evolution is the origin of Allotheria, including Multituberculata and Haramiyida. Multituberculates are the most diverse and best known Mesozoic era mammals andExpand

Fossil evidence of avian crops from the Early Cretaceous of China
The crop is characteristic of seed-eating birds today, yet little is known about its early history despite remarkable discoveries of many Mesozoic seed-eating birds in the past decade. Here we reportExpand

Unique caudal plumage of Jeholornis and complex tail evolution in early birds
Significance We describe the presence of essentially two functional tails in the Early Cretaceous Jeholornis (the second most primitive bird)—one like that of some modern birds with a fan-shapedExpand

Hind Wings in Basal Birds and the Evolution of Leg Feathers
Four-Winged Birds? Recently, nonavialan dinosaurs with feathers on their fore- and hindlimbs have been described. Zheng et al. (p. 1309) describe eleven basal avialan fossils with clear evidence ofExpand

A short-armed dromaeosaurid from the Jehol Group of China with implications for early dromaeosaurid evolution
Recent discoveries of basal dromaeosaurids from the Early Cretaceous Jiufotang and Yixian formations of Liaoning, China, add significant new information about the transition from non-avian dinosaursExpand

An Early Cretaceous eutherian and the placental–marsupial dichotomy
Molecular estimates of the divergence of placental and marsupial mammals and their broader clades (Eutheria and Metatheria, respectively) fall primarily in the Jurassic period. Supporting theseExpand

Basal paravian functional anatomy illuminated by high-detail body outline
Body shape is a fundamental expression of organismal biology, but its quantitative reconstruction in fossil vertebrates is rare. Due to the absence of fossilized soft tissue evidence, the functionalExpand
