A basal ceratopsian with transitional features from the Late Jurassic of northwestern China
TLDR
Character distributions along the marginocephalian lineage reveal that, compared to the bipedal Pachycephalosauria, the dominantly quadrupedal ceratopsians lost many marginocesphalian features and evolved their own characters early in their evolution. Expand
Osteology and Relationships of Byronosaurus jaffei (Theropoda: Troodontidae)
TLDR
Several interesting characters of Byronosaurus jaffei have implications both for theropod relationships and for understanding patterns of variation within coelurosaurian theropods. Expand
A Jurassic ceratosaur from China helps clarify avian digital homologies
TLDR
A new basal Ceratosaur from the Oxfordian stage of the Jurassic period of China is reported, representing the first known Asian ceratosaur and the only known beaked, herbivorous Jurassic theropod, and possesses a strongly reduced manual digit I, documenting a complex pattern of digital reduction within the Theropoda. Expand
The Earliest Pterodactyloid and the Origin of the Group
TLDR
Phylogenetic comparative methods support this reconstruction of a terrestrial origin and a predominantly terrestrial history for the Pterodactyloidea by means of a significant correlation between wing shape and environment also found in modern flying vertebrates, indicating that pterosaurs lived in or were at least adapted to the environments in which they were preserved.

A nesting dinosaur
TLDR
The specimen described here is the first preserved well enough to determine its precise relationship with the nest, and provides the strongest evidence yet for the presence of avian brooding behaviour in non-avian dinosaurs. Expand
An oviraptorid skeleton from the late Cretaceous of Ukhaa Tolgod, Mongolia, preserved in an avianlike brooding position over an oviraptorid nest. American Museum novitates ; no. 3265
The articulated postcranial skeleton of an oviraptorid dinosaur (Theropoda, Coelurosauria) from the Late Cretaceous Djadokhta Formation of Ukhaa Tolgod, Mongolia, is preserved overlying a nest. TheExpand
A New Rhamphorhynchid Pterosaur from the Upper Jurassic of Xinjiang, China, and the Phylogenetic Relationships of Basal Pterosaurs
ABSTRACT A new rhamphorhynchid pterosaur species, Sericipterus wucaiwanensis, gen. et sp. nov., is described from the Upper Jurassic part of the Shishugou Formation in the Xinjiang AutonomousExpand
A basal tyrannosauroid dinosaur from the Late Jurassic of China
The tyrannosauroid fossil record is mainly restricted to Cretaceous sediments of Laurasia, although some very fragmentary Jurassic specimens have been referred to this group. Here we report a newExpand
A Middle Jurassic ‘sphenosuchian’ from China and the origin of the crocodylian skull
TLDR
Important features of the modern crocodylian skull evolved during a phase when the postcranial skeleton was evolving towards greater cursoriality, rather than towards their current semi-aquatic habitus. Expand
PROBLEMS DUE TO MISSING DATA IN PHYLOGENETIC ANALYSES INCLUDING FOSSILS: A CRITICAL REVIEW
TLDR
Missing data simply represent the unknown and should not be viewed as an impediment to considering all available evidence in phylogenetic analyses, nor used as justification for excluding specific taxa or characters. Expand
