The predatory ecology of Deinonychus and the origin of flapping in birds. [PDF]
PLoS ONE, 2011 Most non-avian theropod dinosaurs are characterized by fearsome serrated teeth and sharp recurved claws. Interpretation of theropod predatory ecology is typically based on functional morphological analysis of these and other physical features.

Paravian Phylogeny and the Dinosaur-Bird Transition: An Overview [PDF]
Frontiers in Earth Science, 2019 Recent years witnessed the discovery of a great diversity of early birds as well as closely related non-avian theropods, which modified previous conceptions about the origin of birds and their flight. We here present a review of the taxonomic composition

The endocranium and trophic ecology of Velociraptor mongoliensis. [PDF]
J Anat, 2020 We reconstructed the brain cavity and inner ear of Velociraptor to better understand its lifestyle and hunting abilities. We found brain structures that are present in modern birds, indicating an exceptional sense of balance and agility. The inner ear also closely resembles that of flightless birds, and Velociraptor had a similar hearing ability to ...

Iridescent plumage in a juvenile dromaeosaurid theropod dinosaur
Acta Palaeontologica Polonica, 2023 Colour reconstructions have provided new insights into the lives of dinosaurs and other extinct animals, by predicting colouration patterns from fossilised pigment-bearing organelles called melanosomes.

The first giant raptor (Theropoda: Dromaeosauridae) from the Hell Creek Formation [PDF]
Paleontological Contributions, 2015 ABSTRACT Most dromaeosaurids were small- to medium-sized cursorial, scansorial, and arboreal, sometimes volant predators, but a comparatively small percentage grew to gigantic proportions. Only two such giant “raptors” have been described from North America. Here, we describe a new giant dromaeosaurid, Dakotaraptor steini gen. et sp.

Journal of Anatomy, Volume 242, Issue 6, Page 1124-1145, June 2023., 2023 Spinosaurids were unusual large‐bodied tetanuran theropods with semi‐aquatic ecologies. The neuroanatomy of baryonychine spinosaurids has yet to be studied, and may inform about the early evolution of the spinosaurid brain and sensory capabilities. With unexceptional hearing and olfaction, baryonychine endocasts share morphological similarities with ...

Papers in Palaeontology, Volume 9, Issue 2, March/April 2023., 2023 Abstract Current research suggests that the initial radiation of maniraptoran theropods occurred in the Middle Jurassic, although their fossil record is known almost exclusively from the Cretaceous. However, fossils of Jurassic maniraptorans are scarce, usually consisting solely of isolated teeth, and their identifications are often disputed.
