ABSTRACT A new dromaeosaurid dinosaur—Velociraptor osmolskae n. sp.—is described on the basis of associated paired maxillae and a left lacrimal discovered in Campanian (Upper Cretaceous) deposits at Bayan Mandahu (Inner Mongolia, P. R. China). The maxilla of this new taxon is characterized by its long rostral plate and its enlarged, teardrop-shaped ...

An ungual phalanx of a dromaeosaurid dinosaur from near Blagoveshchensk was studied for the first time. The occurrence of dromaeosaurids apart from other taxa of dinosaurs is evidence of the high biodiversity of the Amur region before the Cretaceous–Paleogene event.

Comparison of forelimb function betweenDeinonychusandBambiraptor(Theropoda: Dromaeosauridae)
Abstract Fossils and casts of forelimb bones of the dromaeosaurids Deinonychus antirrhopus and Bambiraptor feinbergi were manually manipulated to determine range of motion and to test functional hypotheses. Shoulder motion in Bambiraptor resembles that found by a previous study on Deinonychus.

The recent discovery of the early dromaeosaurid Sinornithosaurus millenii Xu et al. 1999 is especially important for our understanding of maniraptoran evolution, particularly of avian origins. This paper presents a thorough description of the skull of this species, revises the diagnosis based on cranial features, and discusses similarities to those of

Abstract Skeletal remains of dromaeosaurid theropods are uncommon in the richly fossiliferous continental strata of the Upper Cretaceous (Turonian) Bissekty Formation of the Kyzylkum Desert in Uzbekistan. The phylogenetic position of the first published specimen, a partial braincase designated as the holotype of Itemirus medullaris Kurzanov, 1976 ...
