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

open access: yes, 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.

On the Classification of the Dinosauria, with observations on the Dinosauria of the Trias [PDF]

open access: yesQuarterly Journal of the Geological Society of London, 1870
T he recognition of what are now commonly termed the Dinosauria , as a peculiar group of the Reptilia , is due to that remarkable man whose recent death all who are interested in the progress of sound palæeontology must deplore–Hermann von Meyer.

A new dromaeosaurid (Dinosauria: Theropoda) from the Upper Cretaceous Wulansuhai Formation of Inner Mongolia, China [PDF]

open access: yes, 2010
We describe a new dromaeosaurid theropod from the Upper Cretaceous Wulansuhai Formation of Bayan Mandahu, Inner Mongolia. The new taxon, Linheraptor exquisitus gen. et sp.

Estimating cranial musculoskeletal constraints in theropod dinosaurs [PDF]

open access: yesRoyal Society Open Science, 2015
Many inferences on the biology, behaviour and ecology of extinct vertebrates are based on the reconstruction of the musculature and rely considerably on its accuracy.

Inside a duck-billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

The evolution of large-bodied theropod dinosaurs during the Mesozoic in Asia [PDF]

open access: yes, 2010
The fossil record of large-bodied, apex carnivorous theropod dinosaurs in Eastern Asia is now among the best understood in the world, thanks to new discoveries and reinterpretations of long-neglected fossils.

Taxonomic and stratigraphic update of the material historically attributed to Megalosaurus from Portugal [PDF]

open access: yesActa Palaeontologica Polonica
The first paleontological works on Mesozoic vertebrates from Portugal, carried out from the end of the 19th and the first half of the 20th century, provided the discovery of significant collections of vertebrate fossils.

The first Jurassic theropod from the Sergi Formation, Jatobá Basin, Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2021
Archosaur osteological remains are abundant in Brazil, particularly from the Triassic and Cretaceous strata, but in Jurassic, the record is predominantly represented by ichnofossils.

Variability in biological diversity of dinosaurs and types of their diet [PDF]

open access: yesE3S Web of Conferences, 2023
Biodiversity analysis underlies macroevolutionary studies and allows to identify mass extinctions. Numerous studies of mass extinctions show that geological factors play a central role in determining the diversity dynamics. The late Cretaceous extinction

Postcranial osteology of the first early-stage juvenile skeleton of Plateosaurus trossingensis from the Norian of Frick, Switzerland [PDF]

open access: yesActa Palaeontologica Polonica, 2020
Owing to monospecific mass-accumulation sites in Central Europe, the early-branching sauropodomorph Plateosaurus has one of the best fossil records among dinosaurs. Despite this, early-stage juveniles have been conspicuously absent.
