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 …

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 …

The first definitive Middle Jurassic atoposaurid (Crocodylomorpha, Neosuchia), and a discussion on the genus Theriosuchus
Atoposaurids were a clade of semiaquatic crocodyliforms known from the Late Jurassic to the latest Cretaceous. Tentative remains from Europe, Morocco, and Madagascar may extend their range into the Middle Jurassic. Here we report the first unambiguous Middle Jurassic (late Bajocian–Bathonian) atoposaurid: an anterior dentary from the Isle of Skye,...Young, Mark T ; Tennant, Johnathan P ; Brusatte, Stephen L ; Challands, Thomas James ; Fraser, Nicholas C …

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

Theropod dinosaurs from the Middle Jurassic (Bajocian-Bathonian) of Skye, Scotland
The Isle of Skye, Scotland, has yielded a diverse Middle Jurassic terrestrial vertebrate fauna, but little is known about the predatory dinosaurs (theropods) occupying the top and secondary carnivore roles in these ecosystems, as their fossils have been limited to rare footprints of small- to mid-sized taxa. We describe two...Brusatte, Stephen L ; Clark, Neil D L

New specimen and revision of the late Jurassic teleosaurid 'Steneosaurus’ megarhinus.
Teleosaurids were a successful group of semi-aquatic crocodylomorphs that were an abundant part of coastal marine/lagoonal faunas during the Jurassic. Their fossil record suggests that the group declined in diversity and abundance during the Late Jurassic. 'Steneosaurus’ megarhinus (Hulke, 1871) from the Kimmeridge Clay Formation is a little known gracile...Foffa, Davide ; Young, Mark T ; Brusatte, Stephen L ; Steel, Lorna

The braincase and neurosensory anatomy of an Early Jurassic marine crocodylomorph: Implications for crocodylian sinus evolution and sensory transitions
Modern crocodylians are a morphologically conservative group, but extinct relatives (crocodylomorphs) experimented with a wide range of diets, behaviors, and body sizes. Among the most unusual of these fossil groups is the thalattosuchians, an assemblage of marine-dwellers that transitioned from semiaquatic species (teleosaurids and kin) into purely open-ocean forms (metriorhynchids)...Brusatte, Stephen L ; Muir, Amy ; Young, M T ; Walsh, Stig A ; Steel, L …

A reassessment of the postcanine dentition and systematics of the tritylodontid Stereognathus (Cynodontia, Triltylodontidae, Mammaliamorpha) from the Middle Jurassic of the United Kingdom
Tritylodontidae was a successful advanced cynodont clade with a close relationship to mammals, but falling outside the clade Mammaliaformes. Stereognathus ooliticus was the first tritylodontid to be named and described in 1854, but since then no comprehensive description for this species has been produced. A second species, S. hebridicus, was...Panciroli, Elsa ; Walsh, Stig A ; Fraser, Nicholas C ; Brusatte, Stephen L ; Corfe, Ian

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

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 …
