A revision of the ‘coelophysoid-grade’ theropod specimen from the Lower Jurassic of the Isle of Skye (Scotland )
The broadest diversification of early predatory dinosaurs is represented by the ‘coelophysoid-grade’ neotheropods, but their Hettangian–Sinemurian ( 191–201 Ma) record is scarce worldwide. More information is needed to shed light on the evolution of this dinosaur group after the end-Triassic mass extinction ( 201 Ma). Here we revisit the anatomy...Ezcurra, Martín D ; Marke, Daniel ; Walsh, Stig A ; Brusatte, Stephen L

Widespread azendohsaurids (Archosauromorpha, Allokotosauria) from the Late Triassic of western USA and India
Archosauromorph reptiles underwent rapid lineage diversification, increases in morphological and body size disparity, and expansion into new adaptive landscapes. Several of the primary early archosauromorph clades (e.g. rhynchosaurs) are easy to differentiate from others because of their characteristic body types, whereas the more lizard‐like and carnivorous forms with long necks...Nesbitt, Sterling J ; Stocker, Michelle R ; Ezcurra, Martín D ; Fraser, Nicholas C ; Heckert, Andrew B …

Pendraig milnerae, a new small-sized coelophysoid theropod from the Late Triassic of Wales
We describe a new small-bodied coelophysoid theropod dinosaur, Pendraig milnerae gen. et sp. nov, from the Late Triassic fissure fill deposits of Pant-y-ffynnon in southern Wales. The species is represented by the holotype, consisting of an articulated pelvic girdle, sacrum and posterior dorsal vertebrae, and an associated left femur, and...Spiekman, Stephan N F ; Ezcurra, Martín D ; Butler, Richard J ; Fraser , Nicholas C ; Maidment, Susannah C R
