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
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
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
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
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
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.
Basal Abelisaurid and Carcharodontosaurid Theropods from the Lower Cretaceous Elrhaz Formation of Niger
We report the discovery of basal abelisaurid and carcharodontosaurid theropods from the mid Cretaceous (Aptian—Albian, ca. 112 Ma) Elrhaz Formation of the Niger Republic. The abelisaurid, Kryptops
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
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)]].
Sauropod dinosaurs from the Lower Cretaceous of eastern Asia: taxonomic and biogeographical implications
Sauropod dinosaurs are poorly represented in the Lower Cretaceous of eastern Asia. Here, we describe a number of isolated sauropod teeth from the Kuwajima Formation (?Berriasian–?Hauterivian) of
A new carcharodontosaurid (Dinosauria, Theropoda) from the Upper Cretaceous of Argentina
A new carcharodontosaurid theropod from the Huincul Formation (Aptian-Cenomanian, Upper Cretaceous) of Neuquen Province, Argentina, is described. Approximately the same size as Giganotosaurus
The skull of Monolophosaurus jiangi (Dinosauria: Theropoda) and its implications for early theropod phylogeny and evolution
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.
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
A longirostrine tyrannosauroid from the Early Cretaceous of China
The fossil record of tyrannosauroid theropods is marked by a substantial temporal and morphological gap between small-bodied, Barremian taxa, and extremely large-bodied taxa from the latest

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.
