Carcharodontosaurs were the largest predatory dinosaurs, and their early evolutionary history seems to be more intricate than was previously thought. Until recently, carcharodontosaurs were restricted to a group of large theropods inhabiting the Late Cretaceous Gondwanan land masses, but in the last few years Laurasian evidence has been causing a reevaluation of their initial diversification. Here we describe an almost complete and exquisitely preserved skeleton of a medium-sized (roughly six… 
A New Carcharodontosaurian Theropod from the Lusitanian Basin: Evidence of Allosauroid Sympatry in the European Late Jurassic
ABSTRACT Carcharodontosaurian allosauroids were temporally restricted to the Cretaceous, being known from all land masses with the exception of Antarctica. In addition to Veterupristisaurus from
An Unusual New Theropod with a Didactyl Manus from the Upper Cretaceous of Patagonia, Argentina
A new, partially articulated mid-sized theropod was found in rocks from the Huincul Formation and represents the first likely neovenatorid from this unit, the most basal tetatanuran to exhibit common patterns of digit III reduction that evolved independently in a number of other tetanuran lineages.
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 New Crested Pterosaur from the Early Cretaceous of Spain: The First European Tapejarid (Pterodactyloidea: Azhdarchoidea)
The discovery of Europejara in the Barremian of the Iberian Peninsula reveals an earlier and broader global distribution of tapejarids, suggesting a Eurasian origin of this group.
Carcharodontosaurian remains (Dinosauria, Theropoda) from the Upper Jurassic of Portugal
Abstract A new specimen of a theropod dinosaur found in the Upper Jurassic (Freixial Formation, late Tithonian) of the Lusitanian Basin is described. It corresponds to a single individual and
Abundance of large ornithopod dinosaurs in the El Castellar Formation (Hauterivian-Barremian, Lower Cretaceous) of the Peñagolosa sub-basin (Teruel, Spain)
The El Castellar Formation (upper Hauterivian-lowermost Barremian, Lower Cretaceous) in the southwest of the Maestrat Basin (Spain) has yielded diverse dinosaur remains, mostly fragmentary bones.
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.


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.
The first definitive carcharodontosaurid (Dinosauria: Theropoda) from Asia and the delayed ascent of tyrannosaurids
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.
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
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
A new giant carnivorous dinosaur from the Cretaceous of Patagonia
A new giant carnivorous dinosaur from the Upper Creta-ceous of northwestern Patagonia (Argentina) is reported, characterized by a proportionally low skull, a reduced shoulder girdle, and robust vertebrae and hind limbs, and provides an opportunity to exam-ine the Gondwanan dinosaur palaeocommunities and their relation to those from Laurasia.
The osteology of Neovenator salerii (Dinosauria: Theropoda) from the Wealden Group (Barremian) of the Isle of Wight
Allosauroids were a widespread theropod superfamily, but the best-known representatives are Allosaurus itself (Gilmore, 1920; Madsen, 1976) from North America and Sinraptor (Currie and Zhao, 1993)
A new clade of archaic large-bodied predatory dinosaurs (Theropoda: Allosauroidea) that survived to the latest Mesozoic
It is demonstrated that the problematic allosauroids Aerosteon, Australovenator, Fukuiraptor and Neovenator form a previously unrecognised but ecologically diverse and globally distributed clade (Neovenatoridae, new clade) with the hitherto enigmatic theropods Chilantaisaurus, Megaraptora and the Maastrichtian Orkoraptor.
Phylogeny of Allosauroidea (Dinosauria: Theropoda): Comparative analysis and resolution
A core subset of allosauroids is analysed using cladistic methodology and several comparative methods and the recovered most parsimonious topology shows a strong overall match with the stratigraphical record and is much more congruent with stratigraphy than any alternative topology.
An Early Cretaceous heterodontosaurid dinosaur with filamentous integumentary structures
Tianyulong extends the geographical distribution of heterodontosaurids to Asia and confirms the clade’s previously questionable temporal range extension into the Early Cretaceous period, and represents the first confirmed report, to the authors' knowledge, of filamentous integumentary structures in an ornithischian dinosaur.
The Phylogeny of Ceratosauria (Dinosauria: Theropoda)
A new cladistic analysis of Ceratosauria from the Late Jurassic‐Late Cretaceous of North and South America, Europe, Africa, India and Madagascar suggests that Elaphrosaurus and its relatives are the most basal ceratosaurs, followed by Ceratosaurus and Noasauridae + Abelisauridae (= Abelisauroidea).
