The postcranial skeleton of monolophosaurus jiangi (dinosauria: Theropoda) from the Middle Jurassic of Xinjiang, China, and a review of Middle Jurassic Chinese theropods [PDF]

, 2010
The Middle Jurassic was a critical time in the evolution of theropod dinosaurs, highlighted by the origination and radiation of the large-bodied and morphologically diverse Tetanurae.

Bird-like anatomy, posture, and behavior revealed by an early jurassic theropod dinosaur resting trace. [PDF]

PLoS ONE, 2009
BackgroundFossil tracks made by non-avian theropod dinosaurs commonly reflect the habitual bipedal stance retained in living birds. Only rarely-captured behaviors, such as crouching, might create impressions made by the hands.

Fast-running theropods tracks from the Early Cretaceous of La Rioja, Spain

Scientific Reports, 2021
Theropod behaviour and biodynamics are intriguing questions that paleontology has been trying to resolve for a long time. The lack of extant groups with similar bipedalism has made it hard to answer some of the questions on the matter, yet theoretical ...

T. rex cognition was T. rex-like-A critical outlook on diverging views of the neurocognitive evolution in dinosaurs. [PDF]

Anat Rec (Hoboken)
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Methods of studying early theropod flight

, 2020
The study of early theropod flight involves avialans as well as other pennaraptorans. It requires the study of anatomy that is familiar to the modern ornithologist, but also very different and alien.
