ABSTRACT The ichthyosaur material of the British Middle and Upper Jurassic referable to Ophthalmosaurus icenicus (Ichthyosauria: Ophthalmosauridae) is revisited and re-described; this is the most completely known post-Liassic British ichthyosaur. Much of this material derives from the Callovian Oxford Clay Formation, particularly from the Peterborough Area of Cambridgeshire, UK, deposited in the Leeds Collections. Pre-Callovian ichthyosaur remains are infrequent, incomplete, and non-diagnostic… 
A new Tithonian ophthalmosaurid ichthyosaur from Coahuila in northeastern Mexico
Abstract Historically, Mexican Jurassic ichthyosaurs have been referred to European representatives of the cosmopolitan family-level clade Ophthalmosauridae. Here, we describe one of the most
Revision of Undorosaurus, a mysterious Late Jurassic ichthyosaur of the Boreal Realm
Recent study of ophthalmosaurid ichthyosaurs has brought us a number of new taxa; however, the validity of several ophthalmosaurid taxa from the Volgian (Tithonian) of European Russia still remains
Ichthyosaurs from the Upper Triassic (Carnian–Norian) of the New Siberian Islands, Russian Arctic, and their implications for the evolution of the ichthyosaurian basicranium and vertebral column
TLDR
The first ichthyosaurian specimens discovered from the Upper Triassic of the Russian Arctic (Kotelny Island, New Siberian Islands) are described and anatomy, indicating toretocnemid or parvipelvian affinities, further supports the previously hypothesised sister-group relationships between these two clades.
A prevalence of Arthropterygius (Ichthyosauria: Ophthalmosauridae) in the Late Jurassic—earliest Cretaceous of the Boreal Realm
TLDR
The phylogenetic analyses place the clade of Arthropterygius close to the base of Ophthalmosauria as a sister group either to ophthalmosurines or to platypterygiines, and indicate that at least some ophthalMosaurid genera and species, including Arthropologygius, could be easily recognized based solely on humeral morphology.
A new ichthyosaur from the Late Jurassic of north-west Patagonia (Argentina) and its significance for the evolution of the narial complex of the ophthalmosaurids
TLDR
It is proposed that the division of the external nares (complete or partly osseous) was related functionally to the separation of the air passage from the outlet of nasal salt glands in such a way that the salt glands could be evacuated underwater, while the air passages could be closed by a valvular system.
Internal structure of ichthyosaur rostrum from the Upper Jurassic of Poland with comments on ecomorphological adaptations of ophthalmosaurid skull
ABSTRACT This study presents a detailed analysis of a semi-articulated finding of an ichthyosaur Ophthalmosauridae indet. rostrum fragment from the Upper Jurassic (Oxfordian) in the Morawica quarry
Osteology and phylogeny of Late Jurassic ichthyosaurs from the Slottsmøya Member Lagerstätte (Spitsbergen, Svalbard)
TLDR
The species was recently synonymized with the Russian Undorosaurus gorodischensis, but it is concluded that there are too many differences, for example in the shape of the stapedial head and the proximal head of the humerus; and too little overlap between specimens, to warrant synonymy on species level.
Revision of Nannopterygius (Ichthyosauria: Ophthalmosauridae): reappraisal of the ‘inaccessible’ holotype resolves a taxonomic tangle and reveals an obscure ophthalmosaurid lineage with a wide distribution
TLDR
The Late Jurassic ichthyosaur Nannopterygius is among the poorest known, with the only skeleton on display in the Natural History Museum, London and, therefore, difficult to access, and its lineage was among several ophthalmosaurine lineages that crossed the Jurassic–Cretaceous boundary and survived the Jurassic-Cret Jurassic transition at high latitudes.
A new ophthalmosaurid ichthyosaur from the Upper Jurassic (Early Tithonian) Kimmeridge Clay of Dorset, UK, with implications for Late Jurassic ichthyosaur diversity
TLDR
A well resolved phylogenetic analysis shows T. etchesi as a member of a basal clade within Ophthalmosauridae comprising Nannopterygius, Gengasaurus, Paraophthalmosaurus and Thalassodraco.
Catutosaurus gaspariniae, gen. et sp. nov. (Ichthyosauria, Thunnosauria) of the Upper Jurassic of Patagonia and the Evolution of the Ophthalmosaurids
ABSTRACT Thunnosaurian ichthyosaurs were one of the most successful lineages of Mesozoic tetrapods in terms of adaptation to a pelagic lifestyle. Among them, the ophthalmosaurids are of particular

New Ophthalmosaurid Ichthyosaurs from the European Lower Cretaceous Demonstrate Extensive Ichthyosaur Survival across the Jurassic–Cretaceous Boundary
TLDR
There is currently no evidence that ichthyosaurs were affected by the JCB extinction event, in contrast to many other marine groups.
A New Upper Jurassic Ophthalmosaurid Ichthyosaur from the Slottsmøya Member, Agardhfjellet Formation of Central Spitsbergen
TLDR
The paleobiogeographical implications of this result suggest the presence of a single clade of Boreal ophthalmosaurid ichthyosaurs that existed during the latest Jurassic, a pattern also reflected in the high degree of endemicity among some Boreal invertebrates, particularly ammonoids.

TLDR
A new species of ichthyosaur is described based on a partial articulated specimen from the Middle Jurassic of southwestern Germany that bears numerous similarities in size and in morphology to the Lower Jurassic species of the genus Stenopterygius and provides additional evidence that the major ecological changes hypothesized to have occurred at the end of the Toarcian took place sometime after this point and most likely did not occur suddenly.
