Little is known about the evolution of large-bodied theropod dinosaurs during the Early to mid Cretaceous in Asia. Prior to this time, Asia was home to an endemic fauna of basal tetanurans, whereas terminal Cretaceous ecosystems were dominated by tyrannosaurids, but the intervening 60 million years left a sparse fossil record. Here, we redescribe the enigmatic large-bodied Chilantaisaurus maortuensis from the Turonian of Inner Mongolia, China. We refer this species to a new genus, Shaochilong… 
The osteology of Shaochilong maortuensis, a carcharodontosaurid (Dinosauria: Theropoda) from the Late Cretaceous of Asia
TLDR
It is argued that the vicariant hypothesis of allosauroid biogeography, in which lineages split in concert with the fragmentation of Pangaea, is poorly supported and large-scale patterns of theropod evolution and faunal replacement are discussed.
A Reassessment of Kelmayisaurus petrolicus, a Large Theropod Dinosaur from the Early Cretaceous of China
The Early Cretaceous fossil record of large-bodied theropods from Asia is poor, hindering comparison of Asian predatory dinosaur faunas with those from other continents. One of the few large Asian
A bizarre, humped Carcharodontosauria (Theropoda) from the Lower Cretaceous of Spain
TLDR
An almost complete and exquisitely preserved skeleton of a medium-sized theropod from the Lower Cretaceous series (Barremian stage) Konservat-Lagerstätte of Las Hoyas in Cuenca, Spain is described and it is proposed that Concavenator has integumentary follicular structures inserted on the ulna, as in modern birds.
The evolution of large-bodied theropod dinosaurs during the Mesozoic in Asia
The fossil record of large-bodied, apex carnivorous theropod dinosaurs in Eastern Asia is now among the best understood in the world, thanks to new discoveries and reinterpretations of long-neglected
A New Carcharodontosauria (Theropoda) from the Early Cretaceous of Guangxi, Southern China
TLDR
Cladistic analysis supports the idea that this new large‐bodied theropod dinosaur Datanglong guangxiensis is a primitive member of the Carcharodontosauria in possessing two unambiguous synapomorphies: large external pneumatic foramina and internal spaces present in the lateral surface of ilium, and a peg‐and‐socket ischiac articulation with the ilium.
Osteology and phylogenetic relationships of Tyrannotitan chubutensis Novas, de Valais, Vickers-Rich and Rich, 2005 (Theropoda: Carcharodontosauridae) from the Lower Cretaceous of Patagonia, Argentina
TLDR
A phylogenetic analysis of Carcharodontosauridae is presented that recovers Tyrannotitan as a derived carcharodsaurid, being the sister group of theClade formed by Giganotosaurus and Mapusaurus, all nested in the clade Gigansotosaurini.

A large Cretaceous theropod from Patagonia, Argentina, and the evolution of carcharodontosaurids
TLDR
It is suggested that carcharodontosaurid radiated in Gondwana sharing with spinosaurids the role of top-predators until their extinction in Cenomanian–Turonian times, and offers a better understanding of the evolution of Southern theropod faunas.

Abstract The systematics and taxonomy of the large allosauroid Carcharodontosaurus are reviewed and a new species of this theropod is described from the Late Cretaceous (Cenomanian) Echkar Formation
A new ornithomimid dinosaur with gregarious habits from the Late Cretaceous of China
TLDR
Comparative and phylogenetic studies of ornithomimosaurs prove that these skeletons represent a new taxon that is more derived than Archaeornithomimus and more basal than the clade of [(Anserimimus + Gallimimus) + [Struthiomimus + (Dromiceiomimus)]].

The skull of Monolophosaurus jiangi (Dinosauria: Theropoda) and its implications for early theropod phylogeny and evolution
TLDR
The skull of Monolophosaurus is redescribed, which is one of the most complete basal tetanuran skulls known and the only quality source of cranial data for Middle Jurassic Chinese theropods, and several features suggest a basal position within Tetanurae, which contrasts with most published cladistic analyses.

On Asian ornithopods (Dinosauria: Ornithischia). 3. A new species of iguanodontid dinosaur

  • 1998
TLDR
The anatomy of this new ornithopod is described; it shows a number of similarities to the known species ofIguanodon, but also demonstrates features which are in some instances unique to this taxon, while others seem to be either convergent upon, or transformational with respect to, the more derived hadrosaurid Ornithopods of the Late Cretaceous.
