LARGE carnivorous animals, the top members of the trophic chain, are rare, and flesh-eating dinosaurs were rarer still. For years the only known giant theropods were Tyrannosaums rex1 and the poorly known Deinocheirus mirificus2, both from the Northern Hemisphere, but many important new dinosaurs have been dis-covered in the Southern Hemisphere during the past decade, con-siderably increasing our knowledge of ancient ecosystems. Here we report a new giant carnivorous dinosaur from the Upper… Expand
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. Expand
New Patagonian Cretaceous theropod sheds light about the early radiation of Coelurosauria
TLDR
Bicentenaria amplifies the array of basal coelurosaurs that inhabited Gondwana during the Cretaceous, also including compsognathids, Aniksosaurus and Santanaraptor, and reveals the importance of the new taxon in the understanding of the early diversification of Coelurosauria. Expand
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,Expand
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.

A new megaraptoran theropod dinosaur from the Upper Cretaceous Bajo de la Carpa Formation of northwestern Patagonia
Abstract We describe Tratayenia rosalesi gen. et sp. nov., a new megaraptoran theropod dinosaur from the Upper Cretaceous of Patagonia, Argentina. The holotype consists of a well-preserved, mostlyExpand
A NEW PHYLOGENY OF THE CARNIVOROUS DINOSAURS
The last several years have seen the discovery of many new theropod dinosaur taxa. Data obtained from these and from fragmentary forms not previously utilized in cladistic analyses are examined. AnExpand
Neovenatorid theropods are apex predators in the Late Cretaceous of North America.
TLDR
A giant new species of allosauroid--Siats meekerorum gen. et sp. nov.--is described, providing the first evidence for the cosmopolitan clade Neovenatoridae in North America and demonstrating that the clade endured there into the Late Cretaceous. Expand
THE BRAINCASE OF GIGANOTOSAURUS CAROLINII (DINOSAURIA: THEROPODA) FROM THE UPPER CRETACEOUS OF ARGENTINA
Abstract Giganotosaurus carolinii is one of the largest known theropod dinosaurs. Its remains include a well-preserved braincase that displays a suite of derived characters unique to the animal, andExpand
Theropod (Dinosauria) diversity from the Açu Formation (mid-Cretaceous), Potiguar Basin, Northeast Brazil
Abstract The theropod record from the Cretaceous of northeastern Brazil is rare and consists mostly of isolated and incomplete remains, with only four species described. Here we describe, identifyExpand
Megaraptorid (Theropoda: Tetanurae) Partial Skeletons from the Upper Cretaceous Bajo Barreal Formation of Central Patagonia, Argentina: Implications for the Evolution of Large Body Size in Gondwanan MegaraptoranS
ABSTRACT We describe two partial postcranial skeletons belonging to the enigmatic theropod dinosaur clade Megaraptoridae from the Upper Cretaceous (lower Cenomanian–upper Turonian) Bajo BarrealExpand

The phylogenetic position of the Tyrannosauridae; implications for theropod systematics
TLDR
The inclusion of the Tyrannosauridae within Maniraptora suggests a major adaptive radiation of coelurosaurs within Cretaceous Asiamerica comparable to contemporaneous radiations in various herbivorous dinosaurian clades. Expand
