  author={Pei-ji Chen and Zhi-ming Dong and Shuonan Zhen},
Two spectacular fossilized dinosaur skeletons were recently discovered in Liaoning in northeastern China. Here we describe the two nearly complete skeletons of a small theropod that represent a species closely related to Compsognathus. Sinosauropteryx has the longest tail of any known theropod, and a three-fingered hand dominated by the first finger, which is longer and thicker than either of the bones of the forearm. Both specimens have interesting integumentary structures that could provide… 
A primitive ornithopod from the Early Cretaceous Yixian Formation of Liaoning
A new ornithopod dinosaur is named and described on the basis of two specimens from the Early Cretaceous Yixian Formation at Lujiatun Locality, Liaoning Province, China. Diagnostic features of this
Therizinosauroidea) from the Lower Cretaceous Yixian Formation
Pygostyle was previously considered as a unique structure of ornithothoracine birds, used to maneuver tail feathers. A similar structure from an oviraptorosaurian dinosaur was considered functionally
Pygostyle‐like Structure from Beipiaosaurus (Theropoda, Therizinosauroidea) from the Lower Cretaceous Yixian Formation of Liaoning, China
Abstract  Pygostyle was previously considered as a unique structure of ornithothoracine birds, used to maneuver tail feathers. A similar structure from an oviraptorosaurian dinosaur was considered
A new family of primitive mammal from the Mesozoic of western Liaoning, China
This animal has several derived characteristics, such as well-developed dentary/squamosal articulation, reduced number of tooth, differentiation of premolars and molars in postcanine teeth, and presence of a dorsal process of the premaxilla that is not in contact with the nasal.
Skeletal remains of a small theropod dinosaur with associated soft structures from the Lower Cretaceous Santana Formation of northeastern Brazil
Associated well-preserved, uncrushed skeletal remains, comprising the pelvic girdle, partial sacrum, both femora, and parts of the right tibia and fibula, from the Romualdo Member of the Lower
A primitive enantiornithine bird and the origin of feathers.
A fossil enantiornithine bird, Protopteryx fengningensis gen. et sp. nov., was collected from the Early Cretaceous Yixian Formation of Northern China. It provides fossil evidence of a triosseal canal
Basal tyrannosauroids from China and evidence for protofeathers in tyrannosauroids
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.
New Material of Sinosauropteryx (Theropoda: Compsognathidae) from Western Liaoning, China
This specimen shows some diagnostic features of Sinosauropteryx prima, such as the very short forelimb in relation to hindlimb with the length ratio of humerus plus radius to femur plus tibia just around 30%, and the long and massive first manual ungual subequal in length to radius.
Anatomy of Sinosauropteryx prima from Liaoning, northeastern China
A spectacular pair of Sinosauropteryx skeletons from Jurassic–Cretaceous strata of Liaoning in northeastern China attracted worldwide notoriety in 1996 as the first dinosaurs covered with
An exceptionally preserved Lower Cretaceous ecosystem
Findings include feathered theropod dinosaurs and early birds, which provide additional, indisputable support for the dinosaurian ancestry of birds, and much new evidence on the evolution of feathers and flight.


A unique multitoothed ornithomimosaur dinosaur from the Lower Cretaceous of Spain
A new specimen, the first ornithomimosaur theropod found in Europe, is reported, which suggests an alternative evolutionary process towards the toothless condition in Ornithomi-mosauria, which could be explained by an exaptation.
A new carnosaur (Dinosauria, Theropoda) from the Jurassic of Xinjiang, People's Republic of China
In 1987, a Sino-Canadian expedition known as the Dinosaur Project (China – Canada – Alberta – Ex Terra) discovered a large theropod skeleton in the Upper Jurassic Shishugou Formation of the Junggar
Multituberculate and other mammal hair recovered from Palaeogene excreta
This record constitutes the first tangible evidence that, along with monotremes and therian mammals, multituberculates were hirsuite, and lends support for the presence of this mammalian feature in the most recent common ancestor of these three groups.
Early Cretaceous dinosaur faunas in China: an introduction
  • Z. Dong

  • 1993
Preliminary evidence suggests that during the Early Cretaceous there were separate dinosaur faunas in northern and southern Asia. The northern fauna, the Psittacosaurus fauna, is well known and based
Early Adaptive Radiation of Birds: Evidence from Fossils from Northeastern China
Late Jurassic and Early Cretaceous birds from northeastern China, including many complete skeletons of Confuciusornis, provide evidence for a fundamental dichotomy in the class Aves that may antedate
On the discovery of an oviraptorid skeleton on a nest of eggs at Bayan Mandahu, Inner Mongolia, People's Republic of China
A partial skeleton of Oviraptor (which means egg thief), collected at Bayan Mandahu (Inner Mongolia, People's Republic of China) in 1990 was lying on top of a nest of eggs. Of the six known skeletons
A beaked bird from the Jurassic of China
As the first Jurassic birds to be described from outside Germany, they show that birds with long fingers terminating in large recurved claws were widely distributed and are not found in the Early Cretaceous sediments of the same region, where there is a diverse assemblage of more advanced flying birds with smaller fingers and claws.
The Carnivorous Saurischia in the Jura and Cretaceous Formations, principally in Europe
The carnivorous Saurischia of the jurassic and cretaceous fornations of North America are relatively well known by the many papers principally of Marsh, Osborn, Lambe, Gilmore, and others. All the
Fossilization of feathers
There may be a significant bias in the avian fossil record in favor of inland water habitats because Preservation in terrestrial and normal-marine settings involves very different processes (in amber and in authigenically mineralized coprolites, respectively).
Nest and egg clutches of the dinosaur Troodon formosus and the evolution of avian reproductive traits
Non-avian coelurosaurians possess several primitive features found in crocodilians and several derived features shared with birds (relatively larger and potentially asymmetric eggs, one egg produced per oviduct at a time, loss of egg retention, open nests, brooding).
