Non-avian theropod dinosaurs attained large body sizes, monopolising terrestrial apex predator niches in the Jurassic–Cretaceous. From the Middle Jurassic onwards, Allosauroidea and Megalosauroidea comprised almost all large-bodied predators for 85 million years. Despite their enormous success, however, they are usually considered absent from terminal Cretaceous ecosystems, replaced by tyrannosaurids and abelisaurids. We demonstrate that the problematic allosauroids Aerosteon, Australovenator… 
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.
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 carcharodontosaurian theropod dinosaur occupies apex predator niche in the early Late Cretaceous of Uzbekistan
TLDR
The discovery of Ulughbegsaurus records the geologically latest stratigraphic co-occurrence of carcharodontosaurid and tyrannosauroid dinosaurs from Laurasia, and evidence indicates carcharsauroids remained the dominant predators relative to tyrannosAUroids, at least in Asia, as late as the Turonian.
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 Barreal
Theropod dinosaurs from the Middle Jurassic (Bajocian–Bathonian) of Skye, Scotland
The Isle of Skye, Scotland, has yielded a diverse Middle Jurassic terrestrial vertebrate fauna, but little is known about the predatory dinosaurs (theropods) occupying the top and secondary carnivore
The phylogeny of Tetanurae (Dinosauria: Theropoda)
TLDR
An exhaustive examination of all basal tetanurans and all existing character data, taking advantage of recent discoveries and adding new morphological, temporal and geographic data achieved significantly improved phylogenetic resolution.
Probable basal allosauroid from the early Middle Jurassic Cañadón Asfalto Formation of Argentina highlights phylogenetic uncertainty in tetanuran theropod dinosaurs

One of the oldest known and most complete pre-Late Jurassic tetanuran, the probable allosauroid Asfaltovenator vialidadi gen. et sp.

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 description of Megalosaurus bucklandii (Dinosauria: Theropoda) from the Bathonian of the UK and the relationships of Middle Jurassic theropods

  • 2010
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.
Phylogeny of Allosauroidea (Dinosauria: Theropoda): Comparative analysis and resolution
TLDR
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.
A Megaraptor-like theropod (Dinosauria: Tetanurae) in Australia: support for faunal exchange across eastern and western Gondwana in the Mid-Cretaceous
TLDR
This ulna from the Early Cretaceous Eumeralla Formation of Australia is described, representing the first Australian non-avian theropod with unquestionable affinities to taxa from other Gondwanan landmasses, suggesting faunal interchange between eastern and western Gondwana during the Mid-Cretaceous.
Dragon's Paradise Lost: Palaeobiogeography, Evolution and Extinction of the Largest-Ever Terrestrial Lizards (Varanidae)
TLDR
The palaeobiogeography of Neogene giant varanids is reconstructed and a new (unnamed) species from the island of Timor is identified, rejecting the long-held perception that V. komodoensis became a giant because of insular evolution or as a specialist hunter of pygmy Stegodon.

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)
OVERVIEW OF THE HISTORY OF DISCOVERY, TAXONOMY, PHYLOGENY, AND BIOGEOGRAPHY OF MAJUNGASAURUS CRENATISSIMUS (THEROPODA: ABELISAURIDAE) FROM THE LATE CRETACEOUS OF MADAGASCAR
Abstract We review the historical sequence of discoveries of Majungasaurus crenatissimus, an abelisaurid theropod from the Upper Cretaceous (Maastrichtian) Maevarano Formation, Mahajanga Basin,
Osteology of Cryolophosaurus ellioti (Dinosauria: Theropoda) from the Early Jurassic of Antarctica and implications for early theropod evolution
TLDR
An in-depth morphological description of Cryolophosaurus is pre-sented here, along with a rigorous phylogenetic analysis of theropod relationships consisting of 347 characters and 56 taxa, in an attempt to clarify the relationships of Crylophosaurus and to provide insight into questions sur-rounding early theropid evolution.
New Mid-Cretaceous (Latest Albian) Dinosaurs from Winton, Queensland, Australia
TLDR
The occurrence of Australovenator from the Aptian to latest Albian confirms the presence in Australia of allosauroids basal to the Carcharodontosauridae, and indicates a diverse Early Cretaceous sauropod and theropod fauna in Australia.
Phylogenetic status of Megaraptor namunhuaiquii Novas based on a new specimen from Neuquén, Patagonia, Argentina
TLDR
A new specimen of Megaraptornamunhuaiquii was discovered on the north coast of the Barreales lake, Neuquen, Argentina and offers more information to elucidate its phylogenetic relationships.
