The origin and early evolution of birds
TLDR
There is no evidence for a major or mass extinction of birds at the end of the Cretaceous, nor for a sudden ‘bottleneck’ in diversity that fostered the early Tertiary origination of living bird ‘Orders’. Expand
A new close relative of Carnotaurus sastrei Bonaparte 1985 (Theropoda: Abelisauridae) from the Late Cretaceous of Patagonia
Infoquest Foundation, 160 Cabrini Boulevard #48, New York, New York 10033, U.S.AINTRODUCTIONAbelisaur dinosaurs, theropods with unusual horned skullssuch as Majungatholus (Sampson et al., 1998) andExpand
Sauropod dinosaur embryos from the Late Cretaceous of Patagonia
TLDR
The first known unequivocal embryonic remains of sauropod dinosaurs—the only known non-avian dinosaur embryos from Gondwana—are described from a nesting ground in the Upper Cretaceous stage of Patagonia, Argentina and it is proposed that these specimens belong to the same sauroPod species. Expand
A nesting dinosaur
TLDR
The specimen described here is the first preserved well enough to determine its precise relationship with the nest, and provides the strongest evidence yet for the presence of avian brooding behaviour in non-avian dinosaurs. Expand
The origin of birds and their flight.

THE MESOZOIC RADIATION OF BIRDS
TLDR
A wealth of recent discoveries combined with new phylogenetic analyses have documented the divergence of a number of lineages by the beginning of the Cretaceous, providing insights into the evolutionary development of feathers and other important features of the avian flight system. Expand
A Theropod Dinosaur Embryo and the Affinities of the Flaming Cliffs Dinosaur Eggs
An embryonic skeleton of a nonavian theropod dinosaur was found preserved in an egg from Upper Cretaceous rocks in the Gobi Desert of Mongolia. Cranial features identify the embryo as a member ofExpand
An oviraptorid skeleton from the late Cretaceous of Ukhaa Tolgod, Mongolia, preserved in an avianlike brooding position over an oviraptorid nest. American Museum novitates ; no. 3265
The articulated postcranial skeleton of an oviraptorid dinosaur (Theropoda, Coelurosauria) from the Late Cretaceous Djadokhta Formation of Ukhaa Tolgod, Mongolia, is preserved overlying a nest. TheExpand
A new Senonian peirosaurid (Crocodylomorpha) from Argentina and a synopsis of the South American Cretaceous crocodilians
ABSTRACT Lomasuchus palpebrosus no v. gen. et sp., from the Upper Cretaceous of northwestern Patagonia (Argentina), is described. Lomasuchus is a “mesosuchian” crocodile with a relatively narrowExpand
