ABSTRACT The discovery of a new dentary of “Stenonychosaurus inequalis” with six germ teeth prompted a critical examination of all jaws and teeth attributed to Troodon, Stenonychosaurus, and Pectinodon. It is concluded that Troodon is the senior synonym of these genera, and that the name Troodontidae has priority over Saurornithoididae. Troodontid dentaries are unique amongst the Theropoda in that they lack interdental plates. Previous reports that Dromaeosaurus, Deinonychus, and… 

The first juvenile dromaeosaurid (Dinosauria: Theropoda) from Arctic Alaska

TLDR
This is the first confirmed non-dental fossil specimen from a member of Dromaeosauridae in the Arctic, expanding on the role of Beringia as a dispersal route for this clade between Asia and North America.

A New Troodontid (Theropoda: Troodontidae) from the Lower Cretaceous Yixian Formation of Western Liaoning, China

TLDR
A specimen collected from the Lower Cretaceous Yixian Formation of western Liaoning, China, represents a new genus and species of troodontid theropod, indicating a rapid evolution at the base of the Troodontidae.

The first appearance of Troodon in the Upper Cretaceous site of Danek Bonebed, and a reevaluation of troodontid quantitative tooth morphotypes

The systematic position of the small theropod dinosaur Troodon has had a confusing history and has been identified at different times as a lizard, a pachycephalosaurid, and a coelurosaurid. Troodon

A New Troodontid Theropod from the Late Cretaceous of Central China, and the Radiation of Asian Troodontids

A new troodontid dinosaur, Xixiasaurus henanensis gen. et sp. nov., from the Upper Cretaceous Majiacun Formation of the Xixia Basin, Henan Province, is erected, based on a partial skull. It is

Troodontids (Theropoda) from the Dinosaur Park Formation, Alberta, with a description of a unique new taxon: implications for deinonychosaur diversity in North America

Troodontids are known from Asia and North America, with the most complete specimens from the Jurassic of China and the Cretaceous of Mongolia. North American troodontids are poorly known, and

Abstract The dinosaur fauna from the Barremian locality of Una, east-central Spain, is described on the basis of isolated teeth. Apart from an unidentified sauropod and a probably new basal

The Dentition of Megalosaurid Theropods

TLDR
A discriminant analysis performed on a dataset of numerical data collected on the teeth of 62 theropod taxa reveals that megalosaurid teeth are hardly distinguishable from other theropid clades with ziphodont dentition.

A Review of the Mongolian Cretaceous Dinosaur Saurornithoides (Troodontidae: Theropoda)

TLDR
The morphology, taxonomy, and phylogenetic relationships of the upper Cretaceous Mongolian troodontid Saurornithoides are reviewed, and empirical support for this clade is currently tenuous.

Cranial anatomy of Stenonychosaurus inequalis (Saurischia, Theropoda) and its bearing on the origin of birds

TLDR
The middle ear cavity is well defined and is connected to at least two systems of sinuses in the skull bones, which strengthen the claim that small carnivorous dinosaurs are more plausible bird ancestors than either pseudosuchians or crocodiles.

A new Coelurid dinosaur from the Belly River Cretaceous of Alberta

It has long been recognized by vertebrate palzeontologists that one or more undescribed members of the carnivorous dinosauria are present in the Belly River fauna, as indicated by certain fragmentary

Dentaries of small theropods from the Judith River Formation (Campanian) of Alberta, Canada

Three dentaries of small theropod dinosaurs from the Judith River Formation of Alberta are described and their taxonomy is discussed. Two are referable to the Dromaeosauridae (Dromaeosaurus sp.) and

A new small theropod dinosaur from the Judith River Formation (Campanian) of Alberta Canada.

TLDR
A new small theropod dinosaur is described from the Judith River Formation of south-central Alberta by an incomplete skeleton and three frontals, which resembles Stenonychosaurus in the structure of the frontal and the Dromaeosauridae in the shape of the endocranial cavity and other skeletal features.
