Deinonychosaurian theropods, the dinosaurian sister group of birds, are characterized by a large raptorial claw borne on a highly modified second digit that was thought to be held in a retracted position during locomotion. In this study, we present new trackway evidence for two coeval deinonychosaurian taxa from the Early Cretaceous of Shandong, China that indicate a hitherto unrecognized body size diversity for this period and continent. These fossil tracks confirm diversity and locomotory… Expand

Dinosaurs of Korea
Numerous tracks of ornithopods, theropods, and sauropod dinosaurs have occurred in the Cretaceous basins mainly located in south east and south of the Korean Peninsula. In addition, diverse fossilsExpand
The global record of Cretaceous tetrapod footprints is dominated by the tracks of non-avian dinosaurs and birds; fewer tracks are known of pterosaurs, crocodylians, turtles, mammals, and otherExpand
Tetrapod track assemblages from Lower Cretaceous desert facies in the Ordos Basin, Shaanxi Province, China, and their implications for Mesozoic paleoecology
Tetrapod ichnofaunas are reported from desert, playa lake facies in the Lower Cretaceous Luohe Formation at Baodaoshili, Shaanxi Province, China, which represent the first Asian example of anExpand
Sauropod and theropod dinosaur tracks from the Upper Cretaceous of Mendoza (Argentina): Trackmakers and anatomical evidences
Abstract New findings of dinosaur ichnites from Agua del Choique section (Mendoza Province, Argentina) provides ichnological and anatomical information about the Cretaceous sauropods and theropods.Expand
Hints of the Early Jehol Biota: Important Dinosaur Footprint Assemblages from the Jurassic-Cretaceous Boundary Tuchengzi Formation in Beijing, China
New reports of dinosaur tracksites in the Tuchengzi Formation in the newly established Yanqing Global Geopark, Beijing, China, support previous inferences that the track assemblages from this formation are saurischian-dominated, with the majority of well-preserved tracks conforming to the Grallator type (sensus lato), thus representing relatively small trackmakers.

Pennaraptoran Theropod Dinosaurs Past Progress and New Frontiers
A theropod track assemblage including large deinonychosaur tracks from the Lower Cretaceous of Asia
Abstract A total of more than 40 tridactyl and didactyl tracks were preserved as natural casts on four fallen blocks of sandstone representing the Lower Cretaceous Jiaguan Formation of Gulin CountyExpand
Large Theropod Dinosaur Footprint Associations in Western Gondwana: Behavioural and Palaeogeographic Implications
In modern terrestrial ecosystems, the population size of large predators is low, and a similar pattern has usually been assumed for dinosaurs. However, fossil finds of monospecific, large theropodExpand
Didactyl Tracks of Paravian Theropods (Maniraptora) from the ?Middle Jurassic of Africa
The new ichnotaxon takes an important position in the ichnological fossil record of Gondwana and the mid-Jurassic biota worldwide, because it is among the earliest known records of paravian maniraptorans and of didactyl theropod tracks from Africa. Expand
Multiple parallel deinonychosaurian trackways from a diverse dinosaur track assemblage of the Lower Cretaceous Dasheng Group of Shandong Province, China
Many newly-discovered dinosaur tracksites have recently been reported from the Lower Cretaceous Dasheng Group of Shandong Province. These are proving valuable as tools for characterizing the fauna inExpand


A basal troodontid from the Early Cretaceous of China
The discovery of Sinovenator and the examination of character distributions along the maniraptoran lineage indicate that principal structural modifications toward avians were acquired in the early stages of manIRaptoran evolution. Expand
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. Expand
Earliest zygodactyl bird feet: evidence from Early Cretaceous roadrunner-like tracks
The tracks demonstrate the existence of a Cretaceous bird not currently represented in the body fossil record that occupied a roadrunner (Geococcyx)-like niche, indicating a previously unknown degree of Cret Jurassic avian morphological and behavioral diversity that presaged later Cenozoic patterns. Expand
New information on Cretaceous troodontids (Dinosauria, Theropoda) from the People's Republic of China
Troodontid specimens were recovered from three localities in China by the Sino-Canadian expeditions between 1987 and 1990. These include a Lower Cretaceous form (Sinornithoides youngi), which is theExpand
A Basal Dromaeosaurid and Size Evolution Preceding Avian Flight
Change in theropod body size leading to flight's origin was not unidirectional, and the two dinosaurian lineages most closely related to birds, dromaeosaurids and troodontids, underwent four independent events of gigantism, and in some lineages size increased by nearly three orders of magnitude.

Taphonomy and paleobiological implications of Tenontosaurus-Deinonychus associations
ABSTRACT The discovery of a nearly complete skeleton of Tenontosaurus tilletti and closely associated multiple shed teeth of the dromaeosaur Deinonychus antirrhopus provides evidence that may supportExpand
The earliest dromaeosaurid theropod from South America
A near-complete, small dromaeosaurid is described that is both the most complete and the earliest member of the Maniraptora from South America and which provides new evidence for a unique Gondwanan lineage of DromaeOSauridae with an origin predating the separation between northern and southern landmasses.

A primitive therizinosauroid dinosaur from the Early Cretaceous of Utah
A new, primitive therizinosauroid is described from an extensive paucispecific bonebed at the base of the Cedar Mountain Formation of east-central Utah, indicating that this species documents the earliest known stage in the poorly understood transition from carnivory to herbivory within Therizinosauroidea.
