Abelisaurids are a clade of large, bizarre predatory dinosaurs, most notable for their high, short skulls and extremely reduced forelimbs. They were common in Gondwana during the Cretaceous, but exceedingly rare in the Northern Hemisphere. The oldest definitive abelisaurids so far come from the late Early Cretaceous of South America and Africa, and the early evolutionary history of the clade is still poorly known. Here, we report a new abelisaurid from the Middle Jurassic of Patagonia… 
A new abelisaurid dinosaur from the Late Cretaceous of southern France: Palaeobiogeographical implications
Abstract The Abelisauridae are a family of mainly Cretaceous theropod dinosaurs with a wide distribution across the Gondwanan land masses. Although their presence in Europe was reported twenty-five
A reappraisal of a putative record of abelisauroid theropod dinosaur from the Middle Jurassic of England
Abstract Abelisauroidea are a recently recognized clade of theropod dinosaurs that have a predominantly Gondwanan distribution. Recently, a distal theropod tibia from the Middle Jurassic of England
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.
A new medium-sized abelisaurid (Theropoda, Dinosauria) from the late cretaceous (Maastrichtian) Allen Formation of Northern Patagonia, Argentina
Abstract Abelisaurid theropods are well known in Cretaceous beds along South America, particularly Patagonia. However, the record of latest Cretaceous abelisauroids is still far from satisfactory.
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 new megalosaurid theropod dinosaur from the late Middle Jurassic (Callovian) of north-western Germany: Implications for theropod evolution and faunal turnover in the Jurassic
Fragmentary remains of a large, robustly built theropod dinosaur were recovered from the marine middle Callovian Ornatenton Formation of north-eastern Northrhine-Westphalia, Germany. The specimen
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 Theropod Dinosaur from the Late Jurassic Cañadón Calcáreo Formation of Central Patagonia, and the Evolution of the Theropod Tarsus
Abstract. A fragmentary postcranial skeleton from the Late Jurassic (Oxfordian—Tithonian) Cañadón Calcáreo Formation of Chubut, Argentina, represents a new taxon of theropod dinosaur, which is here
Phylogenetic analysis of Gondwanan basal eusauropods from the Early-Middle Jurassic of Patagonia, Argentina
Gondwanan Jurassic non-neosauropod eusauropods are key for the understanding of sauropod evolution, although their phylogenetic interrelationships remain poorly understood. However, following the
Ceratosaur palaeobiology: new insights on evolution and ecology of the southern rulers
The results presented here suggest that abelisaurids had different soft tissues on the skull which might have been associated with evolution of a strong cervicocephalic complex and should have allowed derived taxa to have low-displacement headbutting matches.


Abstract The fossil record of abelisauroid carnivorous dinosaurs was previously restricted to Cretaceous sediments of Gondwana and probably Europe. The discovery of an incomplete specimen of a new
A Large Abelisauroid Theropod Dinosaur from the Early Cretaceous of Libya
Abstract Despite increasingly intensive paleontological sampling, Cretaceous terrestrial vertebrates from continental Africa remain relatively poorly known, frustrating efforts to characterize
An abelisauroid dinosaur from the Middle Jurassic of Laurasia and its implications on theropod palaeobiogeography and evolution
Abstract We review here the phylogenetic relationships of a theropod distal end of tibia (MB. R.2351) from the Middle Jurassic Stonesfield Slate (Taunton Formation, middle Bathonian) of Oxfordshire,
Dinosaur remains from the Lower Cretaceous of the Chubut Group, Argentina
Abstract Some fragmentary dinosaur remains from the uppermost Hauterivian–Barremian La Paloma Member of the Cerro Barcino Formation of northern Chubut, Argentina are described. Together with the
A Middle Jurassic heterodontosaurid dinosaur from Patagonia and the evolution of heterodontosaurids
A new ornithischian dinosaur from the Middle Jurassic Cañadón Asfalto Formation in central Patagonia, Argentina is reported, and derived features of its anatomy indicate that Manidens belongs to Heterodontosauridae, as the sister taxon of HeterODontosaurus and other South African heterodontsaurids.
A new carnivorous dinosaur from the Late Jurassic Solnhofen archipelago
A cladistic analysis indicates that the new theropod dinosaur described from the Late Jurassic period of Schamhaupten in southern Germany is closer to maniraptorans than to tyrannosauroids, grouping it with taxa often considered to be compsognathids.
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
New dinosaurs link southern landmasses in the Mid–Cretaceous
Fossils from three stratigraphic levels in the Cretaceous of Niger provide definitive evidence that abelisauroid dinosaurs and their immediate antecedents were also present on Africa and provide key evidence for continued faunal exchange among Gondwanan landmasses until the end of the Early Cret Jurassic.
A Basal Alvarezsauroid Theropod from the Early Late Jurassic of Xinjiang, China
A more complete early specimen is described, dating to about 160 million years ago, which supports the conclusion that Alvarezsauroidea are a basal group of the clade containing both birds and their close theropod relatives and confirms that this group is a basal member of Maniraptora.
A Jurassic mammal from South America
The discovery of a Jurassic mammal represented by a dentary, which is the first, to the authors' knowledge, from South America, indicates that the Australosphenida had diversified and were widespread in Gondwanaland well before the end of the Jurassic, and that mammalian faunas from the Southern Hemisphere already showed a marked distinction from their northern counterparts by the Middle to Late Jurassic.
