RECENT explorations in the West have resulted in the discovery of many remains of Dinosaurs, some of which are of more than ordinary interest. A few are from the Jurassic, but most of them are from the Oretaceous, especially from the upper portion, in the so·called Laramie formation. Those found in the latter horizon show a high degree of specialization, and present some anatomical features not before observed in this group of reptiles. Several of the new forms are briefly described below, and… Expand

An Early Ostrich Dinosaur and Implications for Ornithomimosaur Phylogeny
A new ornithomimosaur from the Yixian Formation of Liaoning Province People's Republic of China is described and this taxon is placed in a phylogenetic analysis of Coelurosauria and shown to be near the base of the ornithological clade. Expand
Ugrosaurus olsoni, a new ceratopsian (Reptilia: Ornithischia) from the Hell Creek Formation of eastern Montana
Fragments of a ceratopsian dinosaur from the Maastrichtian Hell Creek Formation, Garfield County, Montana, are unlike any known ceratopsian. Diagnostic features include a low, rounded nasal boss, anExpand
A New Ornithomimid Theropod from the Dinosaur Park Formation of Alberta, Canada
Fusion of the proximal tarsals to the tibia in some ornithomimid specimens was observed to be more complete than previously recognized, increasing the suite of features that these non-avian dinosaurs share homoplastically with birds. Expand
Shallow marine, nearshore strata of earliest Campanian (Gonioteuthis granulataquadrata belemnite Zone) and latest Early Campanian (informal Belemnellocamax mammillatus belemnite zone) age in theExpand
Ontogenetic and stratigraphic cranial variation in the ceratopsid dinosaur 'Triceratops' from the Hell Creek Formation, Montana
Although they have been considered distinct genera for over a century, ontogenetic analyses reveal that Triceratops and 'Torosaurus' actually represent growth stages of a single genus. Major changesExpand
Late Cretaceous dinosaurs from the Blufftown Formation in western Georgia and eastern Alabama
Fragmentary bones and teeth of three Late Cretaceous dinosaur taxa occur along both sides of the Georgia-Alabama border, in the extreme southeastern Coastal Plain Province. The localities lie in theExpand
The First Dinosaur from Washington State and a Review of Pacific Coast Dinosaurs from North America
The Washington theropod represents one of the northernmost occurrences of a Mesozoic dinosaur on the west coast of the United States and one of only a handful from the Pacific coast of Laramidia during the Cretaceous. Expand
A new ornithomimid dinosaur with gregarious habits from the Late Cretaceous of China
At least fourteen ornithomimid skeletons were recovered from the Upper Cretaceous Ulansuhai Formation in Nei Mongol (Inner Mongolia) Autonomous Region of China. They are assigned to a new genus andExpand
A New Ornithomimosaur from the Lower Cretaceous Trinity Group of Arkansas
ABSTRACT Whereas ornithomimosaurs (ostrich-mimic dinosaurs) are well known from Asia during the Early Cretaceous, they are less well known from this time in North America. Represented by a singleExpand
Early Cretaceous Ornithomimosaurs (Dinosauria: Coelurosauria) from Africa
Abstract. A new genus and species of ornithomimosaur, Afromimus tenerensis, is described based on a fragmentary skeleton from the Lower Cretaceous (Aptian—Albian) El Rhaz Formation of Niger. TheExpand
