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 most derived members of this clade. Tyrannotitan chubutensis, from the Cerro Castaño Member of Cerro Barcino Formation (Albian; Chubut Group), Central Patagonia, Argentina, is of prime interest among Gondwanan carcharodontosaurids as it represents the oldest record of the group. Here we offer a… Expand
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

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
Small-sized abelisaurid (Theropoda: Ceratosauria) remains from the Upper Cretaceous of northwest Patagonia, Argentina
Abstract A new abelisaurid theropod from the Cenomanian of Candeleros Formation (Neuquen Province, NW Patagonia, Argentina) is described. It includes an isolated frontal, partial pelvis, two fusedExpand
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. Expand
The first Jurassic theropod from the Sergi Formation, Jatobá Basin, Brazil.
TLDR
The specimen provides new data to the paleogeographic distribution of carcharodontosaurians before the South America-Africa break-up, as well as understanding the theropod faunal turnover of paleoenvironments during the Jurassic-Cretaceous transition in Brazil. Expand
"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 dinosaursExpand
The cranial osteology of Concavenator corcovatus (Theropoda; Carcharodontosauria) from the Lower Cretaceous of Spain
TLDR
This description provides a detailed revision of the cranial anatomy of carcharodontosaurids, which is relevant to their general phylogenetic relationships and allows for a complete 3D reconstruction of the skull of Concavenator. Expand
New theropod (Tetanurae: Avetheropoda) material from the ‘mid’-Cretaceous Griman Greek Formation at Lightning Ridge, New South Wales, Australia
TLDR
New postcranial theropod material from the early Late Cretaceous Griman Creek Formation at Lightning Ridge is reported, including an associated set consisting of two anterior caudal vertebrae and a pubic peduncle of the ilium, to which a morphologically similar partial vertebral centra from a separate locality is tentatively referred.

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

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.

The Osteology of Chubutisaurus insignis Del Corro, 1975 (Dinosauria: Neosauropoda) from the ‘Middle’ Cretaceous of Central Patagonia, Argentina

The new specimen broadens the temporal and geographical distribution of Peirosauridae during the Cretaceous of Gondwana, representing the southern-most and the most ancient record of the group in Patagonia. Expand
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. Expand
