Troodontid dinosaurs form one of the most avian-like dinosaur groups. Their phylogenetic position is hotly debated, and they have been allied with almost all principal coelurosaurian lineages. Here we report a basal troodontid dinosaur, Sinovenator changii gen. et sp. nov., from the lower Yixian Formation of China. This taxon has several features that are not found in more derived troodontids, but that occur in dromaeosaurids and avialans. The discovery of Sinovenator and the examination of…

A Troodontid Dinosaur from Ukhaa Tolgod (Late Cretaceous Mongolia)
Abstract Here we describe a fragmentary troodontid specimen from the sublocality of Grangers Flats at the Late Cretaceous locality of Ukhaa Tolgod, Omnogov, Mongolia. This specimen is provisionally
A New Troodontid (Theropoda: Troodontidae) from the Lower Cretaceous Yixian Formation of Western Liaoning, China
A specimen collected from the Lower Cretaceous Yixian Formation of western Liaoning, China, represents a new genus and species of troodontid theropod. The new taxon is named and described on the
A new troodontid dinosaur from China with avian-like sleeping posture
The discovery of a new troodontid taxon from the Early Cretaceous Yixian Formation of western Liaoning, China is reported, preserves several features that have been implicated in avialan origins and is preserved in the stereotypical sleeping or resting posture found in extant Aves.
An Early Ostrich Dinosaur and Implications for Ornithomimosaur Phylogeny
A new ornithomimosaur from the Yixian Formation of Liaoning Province People's Republic of China is described and this taxon is placed in a phylogenetic analysis of Coelurosauria and shown to be near the base of the ornithological clade.
A New Troodontid Theropod from the Late Cretaceous of Central China, and the Radiation of Asian Troodontids
A new troodontid dinosaur, Xixiasaurus henanensis gen. et sp. nov., from the Upper Cretaceous Majiacun Formation of the Xixia Basin, Henan Province, is erected, based on a partial skull. It is
A Short-Armed Troodontid Dinosaur from the Upper Cretaceous of Inner Mongolia and Its Implications for Troodontid Evolution
The discovery of Linhevenator suggests that derived troodontids have independently evolved a highly specialized pedal digit II and have significantly shortened the forelimb over the course of their evolution.
A New Troodontid Theropod, Talos sampsoni gen. et sp. nov., from the Upper Cretaceous Western Interior Basin of North America
The presence of a distinct troodontid taxon in the Kaiparowits Formation supports the hypothesis that late Campanian dinosaurs of the Western Interior Basin exhibited restricted geographic ranges and suggests that the taxonomic diversity of Late Cretaceous troodonids from North America is currently underestimated.
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.
New Specimens of Microraptor zhaoianus (Theropoda: Dromaeosauridae) from Northeastern China
New specimens of the diminutive theropod dinosaur Microraptor zhaoianus are described, found to be the sister taxon to other dromaeosaurs and apparently small size is primitive for Deinonychosauria, which has implications for bird origins.


The theropod ancestry of birds: new evidence from the late cretaceous of madagascar
Rahona has a robust, hyperextendible second digit on the hind foot that terminates in a sicklelike claw, a unique characteristic of the theropod groups Troodontidae and Dromaeosauridae.
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
A new family of primitive mammal from the Mesozoic of western Liaoning, China
A fairly well-preserved specimen of a new primitive mammal,Repenomamus robustus gen. et sp. nov., has been described from the Yixian Formation (Lower Cretaceous), western Liaoning, China. This animal
The evolution of dinosaurs.
The ascendancy of dinosaurs on land near the close of the Triassic now appears to have been as accidental and opportunistic as their demise and replacement by therian mammals at the end of the
A juvenile specimen of Saurornithoides mongoliensis from the Upper Cretaceous of northern China
A hind limb of Saurornithoides mongoliensis from the Djadokhta Formation equivalent beds (Upper Cretaceous) of Bayan Mandahu (People's Republic of China) provides more information on the anatomy of
The affinities of a new theropod from the Alxa Desert, Inner Mongolia, People's Republic of China
Remains of bipedal saurischians from lacustrine strata of Albian age in the Alxa ("Alashan") Desert of Inner Mongolia represent a new taxon and the most complete remains of an Early Cretaceous

A new troodontid (Dinosauria, Theropoda) braincase from the Dinosaur Park Formation (Campanian) of Alberta
A new, well-preserved specimen of Troodon formosus is the first to reveal the internal anatomy of the lower part of the braincase. In addition to providing new information on the brain of this high...
The phylogenetic position of the Tyrannosauridae; implications for theropod systematics
The inclusion of the Tyrannosauridae within Maniraptora suggests a major adaptive radiation of coelurosaurs within Cretaceous Asiamerica comparable to contemporaneous radiations in various herbivorous dinosaurian clades.
