Filling the Corallian gap: New information on Late Jurassic marine reptile faunas from England [PDF]
Acta Palaeontologica Polonica, 2018 Two of the best known Mesozoic marine reptile assemblages can be found in units deposited in the Jurassic Sub-Boreal Seaway of the UK: the late Middle Jurassic Oxford Clay Formation (OCF) and Late Jurassic Kimmeridge Clay Formation (KCF). They record two

Determination of muscle strength and function in plesiosaur limbs: finite element structural analyses of Cryptoclidus eurymerus humerus and femur [PDF]
PeerJ, 2022 Background The Plesiosauria (Sauropterygia) are secondary marine diapsids. They are the only tetrapods to have evolved hydrofoil fore- and hindflippers. Once this specialization of locomotion had evolved, it remained essentially unchanged for 135 Ma.

A CRETACEOUS PLESIOSAUR REMAIN (REPTILIA, SAUROPTERYGIA) FROM THE ARGILLE VARICOLORI OF VARZI (PAVIA, LOMBARDY, NORTHERN ITALY) [PDF]
Rivista Italiana di Paleontologia e Stratigrafia, 2017 The first finding of a plesiosaur remain in Italy is reported. The specimen, a single humerus has been collected in the Argille Varicolori formation, in an outcrop close to the village ol Zavattarello near Varzi (Pavia, Lombardy, Northern Italy ...

Quantitative histological models suggest endothermy in plesiosaurs [PDF]
PeerJ, 2018 Background Plesiosaurs are marine reptiles that arose in the Late Triassic and survived to the Late Cretaceous. They have a unique and uniform bauplan and are known for their very long neck and hydrofoil-like flippers.

The completeness of the fossil record of plesiosaurs, marine reptiles from the Mesozoic [PDF]
Acta Palaeontologica Polonica, 2017 Plesiosaurs were a highly successful group of marine reptiles occurring worldwide in the Jurassic and Cretaceous, but to date few studies have focused on their preservation through time.

Bone-eating Osedax worms lived on Mesozoic marine reptile deadfalls. [PDF]
Biol Lett, 2015 We report fossil traces of Osedax, a genus of siboglinid annelids that consume the skeletons of sunken vertebrates on the ocean floor, from early-Late Cretaceous (approx. 100 Myr) plesiosaur and sea turtle bones.

Habitat Availability, Jurassic and Cretaceous Origins of the Deep-Bodied Shark Morphotype and the Rise of Pelagic Sharks. [PDF]
Ecol EvolWe find support for a benthic origin of sharks, with four discrete transitions towards pelagic‐type morphology occurring during the Jurassic and Cretaceous. Increased habitat availability driven by biotic and abiotic environmental change may have driven shifts towards pelagic‐type morphology. These results may help explain discordance between molecular

The fossil vertebrate primary type specimens in the collection of the University of Otago Department of Geology. [PDF]
J R Soc N ZABSTRACT The 47 vertebrate type specimens held in the University of Otago Geology Department are catalogued in detail. A short history of the collection is followed by lists of the type specimens under the Classes Actinopterygii, Reptilia, Aves and Mammalia. A fish trace‐fossil is included at the end of the Actinopterygii.
