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 theropod specimens from this interval is a partial skull (maxilla and dentary) from the Lianmugin Formation (?Valanginian—Albian), the holotype of Kelmayisaurus petrolicus. Most authors have either considered this specimen as an indeterminate basal tetanuran or a nomen dubium. We redescribe K… 
A New Carcharodontosauria (Theropoda) from the Early Cretaceous of Guangxi, Southern China
A new large-bodied theropod dinosaur, Datanglong guangxiensis gen. et sp. nov., was recovered from the Lower Cretaceous Xinlong Formation of the Datang Basin, Guangxi. It is unique in several
A new carcharodontosaurian theropod (Dinosauria: Saurischia) from the Lower Cretaceous of Thailand
TLDR
The phylogenetic analyses revealed that Siamraptor is a basal taxon of Carcharodontosauria, involving a new sight of the paleobiogeographical context of this group.
Osteology and phylogenetic relationships of Tyrannotitan chubutensis Novas, de Valais, Vickers-Rich and Rich, 2005 (Theropoda: Carcharodontosauridae) from the Lower Cretaceous of Patagonia, Argentina
The theropod clade Carcharodontosauridae is a broadly distributed group of large allosauroid theropods. The carcharodontosaurids recorded in the Albian–Cenomanian of Gondwana are the youngest and
The first dinosaurs from the Early Cretaceous Hami Pterosaur Fauna, China
TLDR
Besides the pterosaur Hamipterus and one theropod tooth, these dinosaurs are the first vertebrates reported in this region, increasing the diversity of the fauna as well as the information on Chinese sauropods, further supporting a widespread diversification of somphospondylans during the Early Cretaceous of Asia.
New information on Lonchognathosaurus (Pterosauria: Dsungaripteridae) from the Lower Cretaceous of the southern Junggar Basin (NW China)
Abstract Lonchognathosaurus is a poorly known dsungaripterid pterosaur based on a partial skull from the Lower Cretaceous Lianmuxin Formation of the southern Junggar Basin. In 2001, several
"Megalosaurus cf. superbus" from southeastern Romania: the oldest known Cretaceous carcharodontosaurid (Dinosauria: Theropoda) and its implications for earliest Cretaceous Europe-Gondwana connections
Abstract Some of the best records of continental vertebrates from the Cretaceous of Europe come from Romania, particularly two well-known occurrences of dwarfed and morphologically aberrant dinosaurs
Anatomy, taphonomy, and phylogenetic implications of a new specimen of Eolambia caroljonesa (Dinosauria: Ornithopoda) from the Cedar Mountain Formation, Utah, USA
TLDR
A recently discovered associated partial postcranial skeleton of a large Eolambia caroljonesa is described, providing new anatomical data regarding the vertebral column and pelvic girdle and revealing new information on growth history in a basal hadrosauromorph.
Evolution of the carnivorous dinosaurs during the Cretaceous: The evidence from Patagonia
Patagonia has yielded the most comprehensive fossil record of Cretaceous theropods from Gondwana, consisting of 31 nominal species belonging to singleton taxa and six families: Abelisauridae,
A review of theropod dinosaurs from the Late Jurassic to mid-Cretaceous of Southeast Asia
Abstract Several non-avian theropod dinosaurs, as well as some Mesozoic birds, have been reported from Southeast Asia. The fossils are dominantly found in northeastern Thailand, however, one bizarre
Appendicular Osteology of Concavenator corcovatus (Theropoda; Carcharodontosauridae; Early Cretaceous; Spain)
ABSTRACT The holotype of Concavenator corcovatus (MCCM-LH 6666) is a carcharodontosaurid skeleton from the Lower Cretaceous Las Hoyas fossil site in Spain. The appendicular skeleton of Concavenator

The first definitive carcharodontosaurid (Dinosauria: Theropoda) from Asia and the delayed ascent of tyrannosaurids
TLDR
The discovery of an Asian carcharodontosaurid indicates that this clade was cosmopolitan in the Early to mid Cretaceous and that Asian large-bodied theropod faunas were no longer endemic at this time, and may suggest that the ascent of tyrannosaurids into theLarge-bodied dinosaurian predator niche was a late event that occurred towards the end of the Cret Jurassic.
A NEW SPECIES OF CARCHARODONTOSAURUS (DINOSAURIA: THEROPODA) FROM THE CENOMANIAN OF NIGER AND A REVISION OF THE GENUS
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
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.
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.
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.
A description of Megalosaurus bucklandii (Dinosauria: Theropoda) from the Bathonian of the UK and the relationships of Middle Jurassic theropods
TLDR
Megalosaurus bucklandii (Dinosauria: Theropoda), the oldest named dinosaur taxon, from the Bathonian of England, is a valid taxon diagnosed by a unique character combination of the lectotype dentary, and a new phylogenetic analysis focuses on basal tetanurans, revealing several new results.
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.
