Homologies and homeotic transformation of the theropod ‘semilunate’ carpal [PDF]
Scientific Reports, 2014 The homology of the 'semilunate' carpal, an important structure linking non-avian and avian dinosaurs, has been controversial. Here we describe the morphology of some theropod wrists, demonstrating that the 'semilunate' carpal is not formed by the same carpal elements in all theropods possessing this feature and that the involvement of the lateralmost ...

Journal of Anatomy, EarlyView.A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Cranial functional specialisation for strength precedes morphological evolution in Oviraptorosauria
Communications BiologyOviraptorosaurians were a theropod dinosaur group that reached high diversity in the Late Cretaceous. Within oviraptorosaurians, the later diverging oviraptorids evolved distinctive crania which were extensively pneumatised, short and tall, and had a ...

The Journal of Geology, 2007 Abstract A dinosaur trackway in the Middle Jurassic eolian Entrada Sandstone of southern Utah, U.S.A., exposes three undertracks that we have modeled as isolated tectonic regimes showing the development of fold‐thrust ramp systems induced by the dinosaur’s feet.

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
Journal of Anatomy, EarlyView.The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Body Size as a Driver of Scavenging in Theropod Dinosaurs [PDF]
The American Naturalist, 2016 Theropod dinosaurs dominated Earth's terrestrial ecosystem as a diverse group of predators for more than 160 million years, yet little is known about their foraging ecology. Maintaining a balanced energy budget presented a major challenge for therapods, which ranged from the chicken-sized Microraptor up to the whale-sized Giganotosaurus, in the face of
