Beautifully preserved, nearly complete theropod skeletons from Alberta (Canada) allow re−evaluation of the taxonomic status of North American tyrannosaurids. It is concluded that the most parsimonious interpretation of relationships leads to the separation of the two species of Albertosaurus (sensu Russell 1970) into Gorgosaurus libratus from the Campanian Dinosaur Park Formation and Albertosaurus sarcophagus from the upper Campanian/lower Maastrichtian Horseshoe Canyon Formation. Albertosaurus… Expand
A Problematic Tyrannosaurid (Dinosauria: Theropoda) Skeleton and Its Implications for Tyrannosaurid Diversity in the Horseshoe Canyon Formation (Upper Cretaceous) of Alberta
TLDR
It is shown that only a single species of tyrannosaurid is definitively present in the Horseshoe Canyon Formation, greatly simplifying interpretations of tyrannosaursaurid evolution and ecology in this setting. Expand
Albertosaurus (Dinosauria: Theropoda) material from an Edmontosaurus bonebed (Horseshoe Canyon Formation) near Edmonton: clarification of palaeogeographic distribution
Tyrannosaurid cranial bones — including a maxilla, dentary, and pterygoid — were collected from a monodominant Edmontosaurus bonebed in the Horseshoe Canyon Formation exposed near the city ofExpand
Tyrannosauroid dinosaurs from the Aguja Formation (Upper Cretaceous) of Big Bend National Park, Texas
ABSTRACT Rare remains of tyrannosauroid dinosaurs from the Aguja Formation in West Texas indicate the presence here of a relatively gracile species, comparable in form and adult size toExpand
New Examples of Tyrannosaurus rex from the Lance Formation of Wyoming, United States
ABSTRACT The dinosaur remains from the Upper Cretaceous Lance Formation of Wyoming, USA, have been known since 1870. Most of the fossils that are attributed to theropod dinosaurs are fragmentaryExpand
A new tyrannosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Menefee Formation of New Mexico
TLDR
A new tyrannosaurid represented by an associated skeleton from the lower Campanian Allison Member of the Menefee Formation of New Mexico is reported, and the specimen is made the holotype of the new genus and species Dynamoterror dynastes. Expand
The Anatomy of Dryptosaurus aquilunguis (Dinosauria: Theropoda) and a Review of Its Tyrannosauroid Affinities
TLDR
This description confirms the tyrannosauroid affinities of Dryptosaurus and supports its placement as an “intermediate” taxon bracketed between small, basal forms and the derived, Late Cretaceous tyrannosaurids. Expand
Reassessment of a juvenile Daspletosaurus from the Late Cretaceous of Alberta, Canada with implications for the identification of immature tyrannosaurids
TLDR
The new postorbital provides insights into early Daspletosaurus ontogeny, revealing that the cornual process developed earlier or faster than in other tyrannosaurids. Expand
TYRANNOSAURUS REX FROM THE UPPER CRETACEOUS (MAASTRICHTIAN) NORTH HORN FORMATION OF UTAH: BIOGEOGRAPHIC AND PALEOECOLOGIC IMPLICATIONS
The discovery of a Tyrannosaurus rex specimen from the Upper Cretaceous (Maastrichtian) North Horn Formation provides the first documented occurrence of this theropod dinosaur from an upland,Expand
Osteology of Cryolophosaurus ellioti (Dinosauria: Theropoda) from the Early Jurassic of Antarctica and implications for early theropod evolution
TLDR
An in-depth morphological description of Cryolophosaurus is pre-sented here, along with a rigorous phylogenetic analysis of theropod relationships consisting of 347 characters and 56 taxa, in an attempt to clarify the relationships of Crylophosaurus and to provide insight into questions sur-rounding early theropid evolution. Expand
Evidence for high taxonomic and morphologic tyrannosauroid diversity in the Late Cretaceous (Late Campanian) of the American Southwest and a new short-skulled tyrannosaurid from the Kaiparowits formation of Utah
TLDR
An incomplete skull and postcranial skeleton of an unusual tyrannosaurid from the Kaiparowits Formation of Utah that represents a new genus and species, Teratophoneus curriei, suggests that dinosaur faunas were regionally endemic in the west during the upper Campanian. Expand

A preliminary account of a new tyrannosauroid theropod from the Wessex Formation (Early Cretaceous) of southern England
TLDR
It is concluded that the new genus and species of coelurosaurian theropod dinosaur from the Wessex Formation of the Isle of Wight is one of the earliest and (with the exception of some teeth and an isolated ilium from Portugal) the first from Europe. Expand

TLDR
The analysis of cranial characters and comparison of postcranial features reveal that Tarbosaurus bataar is not the sister taxon of Tyrannosaurus rex, and should be considered a genus distinct from Tyrannosaurus. Expand

Dinosaur Systematics: Theropod teeth from the Judith River Formation of southern Alberta, Canada
TLDR
The identification of theropod teeth has the potential of refining stratigraphic determinations, extending temporal and geographic ranges, indicating relationships, and allowing paleoecological statements to be made on the relative diversity or abundance of certain taxa. Expand

Craniofacial ontogeny in Tyrannosauridae (Dinosauria, Coelurosauria)
TLDR
An increase in tooth width, accompanied by loss of tooth positions, and a global shift from an immature gracile to a mature robust morphotype in the craniofacial skeleton typifies the ontogenetic changes in T. rex. Expand

A paleogeographically based division of the Tyrannosaurinae into the Asiatic forms (Tarbosaurus and possibly Alioramus) and North American forms (Daspletosaurus and Tyranno− saurus) is supported by differences in anatomy of the two groups. Expand
