An almost complete ichthyosaur skeleton 10 m long was discovered in January 2021 at the Rutland Water Nature Reserve in the county of Rutland, UK. This was excavated by a small team of palaeontologists in the summer of the same year. Nicknamed 'The Rutland Sea Dragon', this almost fully articulated skeleton is an example of the large-bodied Early J...
A previously unrecognized specimen of Protoichthyosaurus prostaxalis , LEICT G142.1991, from the Lower Jurassic of Barrow-upon-Soar, Leicestershire, UK, includes an almost complete three-dimensional skull that provides new information on the configuration of the skull roof. The position of the pineal foramen (between the frontals and the parietals)...
Four isolated sauropod axial elements from the Oxford Clay Formation (Callovian, Middle Jurassic) of Peterborough, UK, are described. Two associated posterior dorsal vertebrae show a dorsoventrally elongated centrum and short neural arch, and nutrient or pneumatic foramina, most likely belonging to a non-neosauropod eusauropod, but showing ambiguou...
The holotype of Wahlisaurus massarae is known only from a partial skull and postcranial skeleton from the Lower Jurassic, collected near Normanton on Soar, Nottinghamshire, UK. It is diagnosed relative to other ichthyosaurs on the basis of autapomorphies of the coracoid and a unique combination of characters. Here, we report a second specimen of W....
Brachauchenine pliosaurids were marine macropredatory reptiles that might have been the only evolutionary lineage of pliosaurid plesiosaurians that crossed the Jurassic-Cretaceous boundary. Yet progress in understanding their origins and phylogenetic relationships has been hindered by limited knowledge of Early Cretaceous brachauchenine pliosaurid...
We provide a complete description of one of the oldest plesiosaurians, Stratesaurus taylori from the earliest Hettangian of the United Kingdom. At least 25 apomorphies distinguish S. taylori from the sympatric Thalassiodracon hawkinsii, to which all three specimens of S. taylori were originally referred. Several features of the skull of S. taylori...
Pliosaurids were a long-lived and cosmopolitan group of marine predators that spanned 110 million years and occupied the upper tiers of marine ecosystems from the Middle Jurassic until the early Late Cretaceous. A well-preserved giant pliosaurid skull from the Late Jurassic Kimmeridge Clay Formation of Dorset, United Kingdom, represents a new speci...
The study of latest Neoproterozoic fossils that comprise the Ediacara biota is a relatively new frontier of palaeontology. That it started when it did is due, in no small measure, to the discovery of macrofossils in Charnwood Forest in 1957, and their description in a paper to the Proceedings of the Yorkshire Geological Society by Trevor Ford in 19...
Invasion of the open ocean by tetrapods represents a major evolutionary transition that occurred independently in cetaceans, mosasauroids, chelonioids (sea turtles), ichthyosaurs and plesiosaurs. Plesiosaurian reptiles invaded pelagic ocean environments immediately following the Late Triassic extinctions. This diversification is recorded by three i...

The early history of reptile palaeontology is reviewed in order to assess the different roles played by museums, collections and collectors. The formal characterization and description of several fossil reptile groups (mosasaurs, pterosaurs, ichthyosaurs, plesiosaurs and dinosaurs) is then examined in a series of case histories. Fossil reptile bone...
A newly recognized left exoccipital-opisthotic of a Callovian pliosaur, derived from the Peterborough or lower Stewarby Members of the Oxford Clay Formation of Peterborough, is described and figured. This isolated bone is tentatively identified as belonging to an ‘adult’ individual of Liopleurodon
ferox that is inferred to have had a skull length o...
A new reconstruction of the skull of the elasmosaurid plesiosaur Muraenosaurus leedsii is presented, based on a partial but well preserved specimen. The bony labyrinth of the inner ear is used to orient the skull in the horizontal plane. In the new reconstruction, the skull is higher, with more anteriorly directed orbits and a more vertical suspens...
