Fossils of a predatory dinosaur provide novel information about the evolution of unenlagiines, a poorly known group of dromaeosaurid theropods from Gondwana. The new dinosaur is the largest dromaeosaurid yet discovered in the Southern Hemisphere and depicts bizarre cranial and postcranial features. Its long and low snout bears numerous, small-sized conical teeth, a condition resembling spinosaurid theropods. Its short forearms depart from the characteristically long-armed condition of all…

  • 2009
Hesperonychus is the youngest known member of this lineage, extending the temporal range of the clade by 45 million years, and it is the first microraptorine known from North America, providing further evidence for an affinity between the dinosaur faunas of North America and Asia.

A new dromaeosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Wulansuhai Formation of Inner Mongolia, China

A number of cranial and dental features seen in L. exquisitus and T. mangas suggest that these two taxa are probably intermediate in systematic position between known basal and derived dromaeosaurids, and the discovery of Linheraptor exquis Titus is thus important for understanding the evolution of some salient feature seen in the derived dronaeosaurusids.

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…

The Osteology of Balaur bondoc, an Island-Dwelling Dromaeosaurid (Dinosauria: Theropoda) from the Late Cretaceous of Romania

ABSTRACT The Haţeg Island fauna of the terminal Late Cretaceous (ca. 71–65 million years ago) of Romania is one of the most unusual dinosaur assemblages in the global fossil record. It has long been…

A bony-crested Jurassic dinosaur with evidence of iridescent plumage highlights complexity in early paravian evolution

A distinctive new Yanliao theropod species bearing prominent lacrimal crests, bony ornaments previously known from more basal theropods, and a suite of unusual skeletal and feather characteristics consistent with proposed rapid character evolution and significant diversity in signalling and locomotor strategies near bird origins.

A giant dromaeosaurid theropod from the Upper Cretaceous (Turonian) Bissekty Formation of Uzbekistan and the status of Ulughbegsaurus uzbekistanensis

The Upper Cretaceous (Turonian) Bissekty Formation of Uzbekistan has yielded many isolated bones and teeth representing a variety of non-avian theropod dinosaurs. A pedal phalanx II-2 indicates the…

New Dromaeosaurids (Dinosauria: Theropoda) from the Lower Cretaceous of Utah, and the Evolution of the Dromaeosaurid Tail

A phylogenetic analysis places Y. doellingi in a clade with Utahraptor, Achillobator, and Dromaeosaurus and traces changes in character states of the tail across Coelurosauria to elucidate the evolution of the dromaeosaurid tail.

New Patagonian Cretaceous theropod sheds light about the early radiation of Coelurosauria

Bicentenaria amplifies the array of basal coelurosaurs that inhabited Gondwana during the Cretaceous, also including compsognathids, Aniksosaurus and Santanaraptor, and reveals the importance of the new taxon in the understanding of the early diversification of Coelurosauria.

An aberrant island-dwelling theropod dinosaur from the Late Cretaceous of Romania

A new dromaeosaurid theropod is described, based on an articulated skeleton from the Maastrichtian of Romania, which represents the most complete predatory dinosaur from the middle to Late Cretaceous of Europe and indicates that predators on these islands were not necessarily small, geographically endemic, or primitive.

A Basal Dromaeosaurid and Size Evolution Preceding Avian Flight

Change in theropod body size leading to flight's origin was not unidirectional, and the two dinosaurian lineages most closely related to birds, dromaeosaurids and troodontids, underwent four independent events of gigantism, and in some lineages size increased by nearly three orders of magnitude.
