Dentaries of small theropods from the Judith River Formation (Campanian) of Alberta, Canada [PDF]
, 1977 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 the other to the Saurornithoididae.

Skeletal completeness of the non‐avian theropod dinosaur fossil record
Palaeontology, Volume 62, Issue 6, Page 951-981, November 2019., 2019 Abstract Non‐avian theropods were a highly successful clade of bipedal, predominantly carnivorous, dinosaurs. Their diversity and macroevolutionary patterns have been the subject of many studies. Changes in fossil specimen completeness through time and space can bias our understanding of macroevolution.

The geometry of taking flight: Limb morphometrics in Mesozoic theropods
Journal of Morphology, Volume 276, Issue 2, Page 152-166, February 2015., 2015 ABSTRACT Theropoda was one of the most successful dinosaurian clades during the Mesozoic and has remained a dominant component of faunas throughout the Cenozoic, with nearly 10,000 extant representatives. The discovery of Archaeopteryx provides evidence that avian theropods evolved at least 155 million years ago and that more than half of the tenure of

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Integrative Zoology, EarlyView.This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Dromaeosaurid systematics and evolution. [PDF]
, 2012 206 p. : ill. (some col.), maps ; 26 cm.Coelurosauria is the most diverse clade of theropod dinosaurs. Much of this diversity is present in Paraves--the clade of dinosaurs containing dromaeosaurids, troodontids, and avialans. Paraves has over 160 million

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
