Apparent sixth sense in theropod evolution: The making of a Cretaceous weathervane
TLDR
Dentary groove apertures in certain tyrannosaurid lines (specifically albertosaurines) not only have a unique appearance, but one with significant functional and behavior implications, and it is suggested that these expanded chambers function in perceiving and aligning the body relative to the direction of wind.
The role of ontogeny on character polarization in early dinosaurs: a new specimen from the Late Triassic of southern Brazil and its implications
TLDR
Light is shed on the morphologic pathways seen during dinosauromorph ontogenetic development, which is crucial to more reliably assess phylogenetic reconstructions and macroevolutionary patterns of this widespread and successful group.
Growing up Tyrannosaurus rex: Osteohistology refutes the pygmy “Nanotyrannus” and supports ontogenetic niche partitioning in juvenile Tyrannosaurus
TLDR
Together, the results support the synonomization of “Nanotyrannus” into Tyrannosaurus and fail to support the hypothesized presence of a sympatric tyrannosaurid species of markedly smaller adult body size, but suggest that this species singularly exploited mid- to large-sized theropod niches at the end of the Cretaceous.
New archosauromorph fragments from the Dockum Group of Texas and assessment of the earliest dinosaurs in North America
Abstract Three small and gracile jaw fragments are recovered from the Boren Quarry, one of the lowest fossil quarries of the Upper Triassic Dockum Group of Texas. The specimens are referred to
The Cranial Osteology of Buitreraptor gonzalezorum Makovicky, Apesteguía, and Agnolín, 2005 (Theropoda, Dromaeosauridae), from the Late Cretaceous of Patagonia, Argentina
TLDR
A phylogenetic analysis was performed, recovering Buitreraptor as an unenlagiine dromaeosaurid, in agreement with previous works, including characters not previously considered for this taxon, such as the presence of the mylohyoid foramen.
Assessing ontogenetic maturity in extinct saurian reptiles
TLDR
The various methods that have been used to assess maturity in every major saurian group are described, integrating data from both extant and extinct taxa to give a full account of the current state of the field and providing method‐specific pitfalls, best practices, and fruitful directions for future research.
Size-driven preservational and macroecological biases in the latest Maastrichtian terrestrial vertebrate assemblages of North America
Abstract. The end-Cretaceous (K/Pg) mass extinction event is the most recent and well-understood of the “big five” and triggered establishment of modern terrestrial ecosystem structure. Despite the

A high-resolution growth series of Tyrannosaurus rex obtained from multiple lines of evidence
TLDR
The extreme number of changes at the transition between juveniles and subadults shows that the ontogeny of T. rex exhibits secondary metamorphosis, analogous to the abrupt ontogenetic changes that are seen at sexual maturity among teleosts.

An Unusual Basal Therizinosaur Dinosaur with an Ornithischian Dental Arrangement from Northeastern China
TLDR
A nearly complete, articulated skeleton of a new basal therizinosaur from the Early Cretaceous Yixian Formation of Jianchang County, western part of Liaoning Province is reported, which sheds light on the understanding of anatomy of basal therizinosaurs.
A Reassessment of Kelmayisaurus petrolicus, a Large Theropod Dinosaur from the Early Cretaceous of China
The Early Cretaceous fossil record of large-bodied theropods from Asia is poor, hindering comparison of Asian predatory dinosaur faunas with those from other continents. One of the few large Asian

  • 2010
Magnosaurus nethercombensis from the Lower Bajocian (Middle Jurassic) of Dorset, UK is a valid species, possessing a single autapomorphy: the presence of anteroposteriorly elongate foramina, inclined
Diversity of late Maastrichtian Tyrannosauridae (Dinosauria: Theropoda) from western North America
TLDR
The tooth taxon Aublysodon mirandus was reinstated following the collection of nondenticulate tyrannosaurid premaxillary teeth from late Maastrichtian deposits in western North America, but is a nomen dubium because of the small size of Aublysdon crowns and evidence that some denticles develop late in growth in theropods.
A large Cretaceous theropod from Patagonia, Argentina, and the evolution of carcharodontosaurids
TLDR
It is suggested that carcharodontosaurid radiated in Gondwana sharing with spinosaurids the role of top-predators until their extinction in Cenomanian–Turonian times, and offers a better understanding of the evolution of Southern theropod faunas.
The phylogeny of Tetanurae (Dinosauria: Theropoda)
TLDR
An exhaustive examination of all basal tetanurans and all existing character data, taking advantage of recent discoveries and adding new morphological, temporal and geographic data achieved significantly improved phylogenetic resolution.
The evolution of cranial form and function in theropod dinosaurs: insights from geometric morphometrics
TLDR
It is found that theropod skulls primarily differ in relative anteroposterior length and snout depth and to a lesser extent in orbit size and depth of the cheek region, and oviraptorosaurs deviate most strongly from the “typical” and ancestral theropid morphologies.
Nanotyrannus, a new genus of pygmy tyrannosaur, from the Latest Cretaceous of Montana
Nanotyrannus, type species Gorgosaurus lancensis, is the smallest known tyrannosaurid dinosaur and represents, with Tyrannosaurus rex, the last and most advanced members of the Family Tyran­
New Information on the Cranial Anatomy of Acrocanthosaurus atokensis and Its Implications for the Phylogeny of Allosauroidea (Dinosauria: Theropoda)
TLDR
Systematic analysis of this dataset recovers a single most parsimonious topology placing Acrocanthosaurus atokensis as a member of Allosauroidea, in agreement with several recent analyses that nest the taxon well within Carcharodontosauridae.
Bird-like characteristics of the jaws and teeth of troodontid theropods (Dinosauria, Saurischia)
TLDR
A critical examination of all jaws and teeth attributed to Troodon, Stenonychosaurus, and Pectinodon concluded that Troodon is the senior synonym of these genera, and that the name Troodontidae has priority over Saurornithoididae.
