Scleromochlus and the early evolution of Pterosauromorpha
Pterosaurs, the first vertebrates to evolve powered flight, were key components of Mesozoic terrestrial ecosystems from their sudden appearance in the Late Triassic until their demise at the end of the Cretaceous1,2,3,4,5,6. However, the origin and early evolution of pterosaurs are poorly understood owing to a substantial stratigraphic and morphological...Foffa, Davide ; Dunne, Emma M ; Nesbitt, Sterling J ; Butler, Richard J ; 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 …

First and most northern occurrence of a thalattosuchian crocodylomorph from the Jurassic of the Isle of Skye, Scotland
The Jurassic was a key interval for the evolution of dinosaurs, crocodylomorphs and many other vertebrate groups. In recent years, new vertebrate fossils have emerged from the Early–Middle Jurassic of the Isle of Skye, Scotland; however, much more is known about Skye's dinosaur fauna than its crocodylomorphs. Here we report...Kean, Kim J ; Foffa , Davide ; Johnston, Michela M ; Young, Mark T ; Greitens, Gert …

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 …

Revision of the Late Jurassic deep-water teleosauroid crocodylomorph Teleosaurus megarhinus Hulke, 1871 and evidence of pelagic adaptations in Teleosauroidea
Teleosauroids were a successful group of semi-aquatic crocodylomorphs that were an integral part of coastal marine/lagoonal faunas during the Jurassic. Their fossil record suggests that the group declined in diversity and abundance in deep water deposits during the Late Jurassic. One of the few known teleosauroid species from the deeper...Foffa, Davide ; Johnson, Michela M ; Young, Mark T ; Steel, Lorna ; Brusatte, Stephen L

New theropod dinosaur teeth from the Middle Jurassic of the Isle of Skye, Scotland
The Middle Jurassic is a largely mysterious interval in dinosaur evolution, as few fossils of this age are known worldwide. In recent years, the Isle of Skye has yielded a substantial record of trackways, and a more limited inventory of body fossils, that indicate a diverse fauna of Middle Jurassic...Young, Chloe M E ; Hendrickx, Christopher ; Challands, Thomas James ; Foffa, Davide ; Ross, Dugald A …

An unusual small-bodied crocodyliform from the Middle Jurassic of Scotland, UK, and potential evidence for an early diversification of advanced neosuchians
The Middle Jurassic is a poorly sampled time interval for non-pelagic neosuchian crocodyliforms, which obscures our understanding of the origin and early evolution of major clades. Here we report a lower jaw from the Middle Jurassic (Bathonian) Duntulm Formation of the Isle of Skye, Scotland, UK, which consists of an...Yi, Hongyu ; Tennant, Johnathan P ; Young, Mark T ; Challands, Thomas James ; Foffa, Davide …

A new metriorhynchid crocodylomorph from the Oxford Clay Formation (Middle Jurassic) of England, with implications for the origin and diversification of Geosaurini
Metriorhynchids are an extinct group of Jurassic–Cretaceous crocodylomorphs secondarily adapted to a marine lifestyle. A new metriorhynchid crocodylomorph from the Oxford Clay Formation (Callovian, Middle Jurassic) of England is described. The specimen is a large, fragmentary skull and associated single ramus of a lower jaw uniquely preserved in a septarian...Foffa, Davide ; Young, Mark T ; Brusatte, Stephen L ; Graham, Mark R ; Steel, L

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
