New postcranial remains from the Lealt Shale Formation of the Isle of Skye, Scotland, showcase hidden pterosaur diversity in the Middle Jurassic
The Early to Middle Jurassic transition was significant in pterosaur evolution, during which these volant reptiles exploded in diversity alongside dinosaurs and other animals. It has long been thought, however, that pterosaurs did not develop large wingspans until after the Jurassic, a notion challenged by the recent discovery of in...Jagielska, Natalia ; Challands, Thomas J ; O'Sullivan, Michael ; Ross, Dugald A ; Fraser, Nicholas C …

A skeleton from the Middle Jurassic of Scotland illuminates an earlier origin of large pterosaurs
Pterosaurs were the first vertebrates to evolve flight1,2 and include the largest flying animals in Earth history.3,4 While some of the last-surviving species were the size of airplanes, pterosaurs were long thought to be restricted to small body sizes (wingspans ca. <1.8–1.6 m) from their Triassic origins through the Jurassic,...Jagielska, Natalia ; O’Sullivan, Michael ; Funston, Gregory F ; Butler, Ian B ; Challands, Thomas J …

Novel track morphotypes from new tracksites indicate increased Middle Jurassic dinosaur diversity on the Isle of Skye, Scotland
Dinosaur fossils from the Middle Jurassic are rare globally, but the Isle of Skye (Scotland, UK) preserves a varied dinosaur record of abundant trace fossils and rare body fossils from this time. Here we describe two new tracksites from Rubha nam Brathairean (Brothers’ Point) near where the first dinosaur footprint...dePolo, Paige E ; Brusatte, Stephen L ; Challands, Thomas J ; Foffa, Davide ; Wilkinson, Mark …

Sauropod dinosaur trackways in a Middle Jurassic lagoon on the Isle of Skye, Scotland
The Middle Jurassic was a dynamic interval in dinosaur evolution, but the dinosaur fossil record from this time is extremely poor throughout the world. The Isle of Skye (Scotland) preserves marginal marine and terrestrial deposits of Middle Jurassic age, which have yielded sparse bones, teeth, footprints and small segments of...Brusatte, Stephen L ; Challands, Thomas James ; Ross, Dugald A ; Young, Mark T ; Wilkinson, Mark

Ichthyosaurs from the Jurassic of Skye, Scotland
Fossils of Mesozoic vertebrates are rare in Scotland, particularly specimens of marine reptiles such as plesiosaurs and ichthyosaurs. We describe a suite of ichthyosaur fossils from the Early to Middle Jurassic of Skye, which to our knowledge are the first ichthyosaurs from Scotland to be described and figured in detail....Brusatte, Stephen L ; Young, Mark T ; Challands, Thomas James ; Clark, Neil D L ; Fischer, Valentin …
