Many isolated dinosaur bones and teeth have been recovered from Cretaceous rocks in India, but associated remains are exceedingly rare. We report on the discovery of associated cranial and postcranial remains of a new abelisaurid theropod from latest Cretaceous rocks in western India. The new taxon is characterized by exceptionally elongated supratemporal fenestrae and a unique median nasofrontal protuberance. Postcranial elements include vertebrae and portions of the pelvic girdle and hind… Expand
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.Expand
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-fiveExpand
An abelisaurid from the latest Cretaceous (late Maastrichtian) of Morocco, North Africa
Abstract During the latest Cretaceous, distinct dinosaur faunas were found in Laurasia and Gondwana. Tyrannosaurids, hadrosaurids, and ceratopsians dominated in North America and Asia, whileExpand
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 characterizeExpand
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, KryptopsExpand
Ornithischian dinosaurs are uncommon elements in Late Cretaceous faunal assemblages of many Gondwanan landmasses, particularly Africa. The best-documented post-Cenomanian record of purportedExpand
An Abelisauroid Theropod Dinosaur from the Turonian of Madagascar
A new theropod dinosaur, Dahalokely tokana, from Turonian-aged strata of northernmost Madagascar is represented by a partial axial column andPhylogenetic analysis definitively recovers the species as an abelisauroid theropid and weakly as a noasaurid. Expand
A new desert-dwelling dinosaur (Theropoda, Noasaurinae) from the Cretaceous of south Brazil
The recovered skeletal parts show that the new dinosaur was just over 1 m long, with a unique anatomy among theropods, and a phylogenetic analysis nests the new taxon within the Noasaurinae clade, which is unresolved because of the multiple alternative positions that Noasaurus leali can acquire in the optimal trees.

Morphology and internal structure of two new abelisaurid remains (Theropoda, Dinosauria) from the Adamantina Formation (Turonian – Maastrichtian), Bauru Group, Paraná Basin, Brazil
Abstract The knowledge on the Brazilian theropod fauna is hampered by the limited number of specimens unearthed so far. The most potential deposits for the finding of those dinosaurs are the layersExpand
New theropod dinosaur from the Late Cretaceous of Brazil improves abelisaurid diversity
Abstract The Late Cretaceous Marilia Formation (Bauru Group, Bauru Basin) is a geological unit that occurs on Sao Paulo, Minas Gerais, Goias, and Mato Grosso do Sul states, Brazil. This formationExpand


Eurasiatic elements in the Upper Cretaceous nonmarine biotas of peninsular India
The Upper Cretaceous terrestrial biotas of the Indian peninsula provide a good example of the presence of several taxa recorded previously in the Late Cretaceous-early Palaeocene sequences ofExpand
A bizarre predatory dinosaur from the Late Cretaceous of Madagascar
The occurrence of Masiakasaurus on Madagascar suggests that small-bodied abelisauroids, like their larger-bodied counterparts, were more cosmopolitan, radiating throughout much of Gondwana and paralleling the diversification of small coelurosaur theropods in Laurasia. Expand
A revision of Titanosaurus Lydekker (dinosauria ‐ sauropoda), the first dinosaur genus with a ‘Gondwanan’ distribution
The early appearance of titanosaur ichnofossils and body fossils precludes a vicariant origin for the group, but such a pattern cannot yet be ruled out for lower‐level taxa within Titanosauria. Expand
A long-snouted predatory dinosaur from africa and the evolution of spinosaurids
The close phylogenetic relationship between the new African spinosaurid and Baryonyx from Europe provides evidence of dispersal across the Tethys seaway during the Early Cretaceous. Expand

The view is put forward that Acrocanthosaurus is a Lower Cretaceous representative of the tyrannosaur group, using this term in a broad sense, and is perhaps related to the Cenomanian Spinosaurus and the Wealden Altispinax. Expand
Early Cretaceous Dinosaurs from the Sahara
The discovery of dinosaurian skeletons from Lower Cretaceous beds in the southern Sahara shows that several lineages of tetanuran theropods and broad-toothed sauropods had a cosmopolitan distribution across Pangaea before the onset of continental fragmentation. Expand
The Giant Crocodyliform Sarcosuchus from the Cretaceous of Africa
New fossils of the giant African crocodyliform Sarcosuchus imperator clarify its skeletal anatomy, growth patterns, size, longevity, and phylogenetic position. The skull has an expansive narial bullaExpand
The evolution of dinosaurs.
The ascendancy of dinosaurs on land near the close of the Triassic now appears to have been as accidental and opportunistic as their demise and replacement by therian mammals at the end of theExpand
A Giant Sauropod Dinosaur from an Upper Cretaceous Mangrove Deposit in Egypt
We describe a giant titanosaurid sauropod dinosaur discovered in coastal deposits in the Upper Cretaceous Bahariya Formation of Egypt, a unit that has produced threeTyrannosaurus-sized theropods andExpand
The Complete Skull and Skeleton of an Early Dinosaur
Fossils of Herrerasaurus and younger dinosaurs from Upper Triassic beds in Argentina suggest that the dinosaurian radiation was well under way before dinosaurs dominated terrestrial vertebrate communities in taxonomic diversity and abundance. Expand
