A reappraisal of Polyptychodon (Plesiosauria) from the Cretaceous of England [PDF]

open access: yesPeerJ, 2016
Pliosauridae is a globally distributed clade of aquatic predatory amniotes whose fossil record spans from the Lower Jurassic to the Upper Cretaceous. However, the knowledge of pliosaurid interrelationships remains limited.

Early-diverging plesiosaurs from the Pliensbachian (Lower Jurassic) of northwestern Germany [PDF]

open access: yesPeerJ
The knowledge of Pliensbachian (Early Jurassic, ∼192.9–184.2 Ma) plesiosaurs is notoriously insufficient. Although there have been specimens described from different parts of the world, only three of them have been established as diagnosable taxa.

The cranial anatomy and taxonomy of Peloneustes philarchus (Sauropterygia, Pliosauridae) from the Peterborough Member (Callovian, Middle Jurassic) of the United Kingdom

open access: closedPalaeontology, 2011
Abstract:  Peloneustes philarchus is the most abundant pliosaurid from the Peterborough Member of the Oxford Clay Formation (Callovian) of the UK. It is a valid taxon possessing a unique character combination, including a single autapomorphy: the interdentary symphysis is raised dorsally on a narrow platform.

The giant pliosaurid that wasn’t—revising the marine reptiles from the Kimmeridgian, Upper Jurassic, of Krzyżanowice, Poland [PDF]

open access: yesActa Palaeontologica Polonica, 2021
Marine reptiles from the Upper Jurassic of Central Europe are rare and often fragmentary, which hinders their precise taxonomic identification and their placement in a palaeobiogeographic context.

A new plesiosaur from the Lower Jurassic of Portugal and the early radiation of Plesiosauroidea [PDF]

open access: yes, 2021
A new plesiosaur partial skeleton, comprising most of the trunk and including axial, limb, and girdle bones, was collected in the lower Sinemurian (Coimbra Formation) of Praia da Concha, near São Pedro de Moel in central west Portugal.

The evolution of bone-eating worm diversity in the Upper Cretaceous Chalk Group of the United Kingdom. [PDF]

open access: yesPLoS One
The bone-eating worm Osedax is today a member of the highly adapted invertebrate assemblages associated with whale carcasses on the ocean floor. The worm has also been found in a variety of other vertebrates in marine environments.

A new pliosaurid from the Oxford Clay Formation of Oxfordshire, UK

open access: yesActa Palaeontologica Polonica, 2022
We describe the anatomy of a new longirostrine pliosaurid, Eardasaurus powelli gen. et sp. nov., based on a substantially complete skeleton from the Middle Jurassic Oxford Clay Formation of Oxfordshire, UK.

Youngest occurrences of rhomaleosaurid plesiosaurs indicate survival of an archaic marine reptile clade at high palaeolatitudes [PDF]

open access: yesActa Palaeontologica Polonica, 2015
Rhomaleosaurid plesiosaurians were a common and ecologically significant component of Early Jurassic marine faunas, primarily as large-bodied predators. They declined in abundance and made their last fossil appearance in the Middle Jurassic. However, the
