Synopsis The most comprehensive phylogenetic analysis of the theropod clade Coelurosauria to date, is presented here, with 85 coelurosaurian ingroups and 360 characters, using Allosaurus and Sinraptoras outgroups. The strict consensus tree is highly resolved and has the following topology: Tyrannosauroidea + (Compsognathidae + (Arctometatarsalia + (Ornitholestes + (Therizinosauroidea + (Alvarezsauridae + (Oviraptorosauria + (Avialae + (Troodontidae + Dromaeosauridae)))))))). The analysis places… 

The phylogenetic affinities of the bizarre Late Cretaceous Romanian theropod Balaur bondoc (Dinosauria, Maniraptora): dromaeosaurid or flightless bird?

TLDR
The reinterpretation of Balaur implies that a superficially dromaeosaurid-like taxon represents the enlarged, terrestrialised descendant of smaller and probably volant ancestors, and its phylogenetic placement within Avialae is not biased by character weighting.

New therizinosaurid dinosaur from the marine Osoushinai Formation (Upper Cretaceous, Japan) provides insight for function and evolution of therizinosaur claws

The record of therizinosaurs is rich in Asian countries such as Mongolia and China. Fragmentary therizinosaur specimens have been reported from the Lower and Upper Cretaceous deposits in Japan. One

A New Large-Bodied Oviraptorosaurian Theropod Dinosaur from the Latest Cretaceous of Western North America

TLDR
Phylogenetic analysis indicates that Anzu is most closely related to Caenagnathus collinsi, a taxon that is definitively known only from a mandible from the Campanian Dinosaur Park Formation of Alberta, and the problematic oviraptorosaurs Microvenator and Gigantoraptor are recovered as basal caenagnaths, as has previously been suggested.

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

TLDR
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.

European ornithomimosaurs (Dinosauria, Theropoda): an undetected record

Early Cretaceous ornithomimosaurian theropod dinosaurs have been reported from various localities in Asia, whereas they remain poorly represented and extremely rare in North America, Africa and

A New Troodontid Theropod Dinosaur from the Lower Cretaceous of Utah

TLDR
A theropod maxilla from the Lower Cretaceous Cedar Mountain Formation of Utah is described and a phylogenetic analysis is performed to determine its phylogenetic position, distinctive enough to assign to a new genus and species, Geminiraptor suarezarum.

Anatomy of Juravenator starki (Theropoda: Coelurosauria) from the Late Jurassic of Germany

: We provide a detailed study of the morphology of the holotype of Juravenator starki from the Late Jurassic of the Solnhofen area of southern Germany. The incompletely ossified surface of multiple

A new North American therizinosaurid and the role of herbivory in ‘predatory’ dinosaur evolution

TLDR
It is suggested that hypercarnivory in paravian dinosaurs is a secondarily derived dietary specialization and provide a potential mechanism for the invasion of novel morpho- and ecospace early in coelurosaurian evolution—the loss of obligate carnivory and origin of dietary opportunism.

The phylogenetic position of the Tyrannosauridae: implications for theropod systematics

  • T. Holtz
  • Environmental Science, Geography

TLDR
The inclusion of the Tyrannosauridae within Maniraptora suggests a major adaptive radiation of coelurosaurs within Cretaceous Asiamerica comparable to contemporaneous radiations in various herbivorous dinosaurian clades.

A new ornithomimid dinosaur with gregarious habits from the Late Cretaceous of China

TLDR
Comparative and phylogenetic studies of ornithomimosaurs prove that these skeletons represent a new taxon that is more derived than Archaeornithomimus and more basal than the clade of [(Anserimimus + Gallimimus) + [Struthiomimus + (Dromiceiomimus)]].

Avialan status for Oviraptorosauria

TLDR
A phylogenetic analysis using 195 characters scored for four outgroup and 13 maniraptoriform (ingroup) terminal taxa, including new data on ovirptorids places Oviraptorosauria within Avialae, in a sister−group relationship with Confuciusornis.

New information on the anatomy and relationships of Dromaeosaurus albertensis (Dinosauria: Theropoda)

TLDR
Repreparation and restudy of the holotype of Dromaeosaurus albertensis has produced new anatomical information useful for evaluating the relationships of dromaeosaurids.

A primitive therizinosauroid dinosaur from the Early Cretaceous of Utah

TLDR
A new, primitive therizinosauroid is described from an extensive paucispecific bonebed at the base of the Cedar Mountain Formation of east-central Utah, indicating that this species documents the earliest known stage in the poorly understood transition from carnivory to herbivory within Therizinosauroidea.

TLDR
Reexamination of the holotype revealed the presence of several autapomorphies that provide the basis for a revised diagnosis of Microvenator celer, the earliest known oviraptorosaurian or ovarian theropod represented by diagnostic skeletal remains.

Phylogeny of Drepanosauridae (Reptilia: Diapsida)

TLDR
Phylogenetic analysis reveals that the Triassic diapsid family Drepanosauridae is closely related to Coelurosauravus and Longisquama and Avicephala is a sister taxon to Neodiapsida.
