Abstract New plesiosaur remains from the Upper Cretaceous Lopez de Bertodano Formation (late Campanian-Maastrichtian) of Seymour Island, Antarctic Peninsula include Cryptoclididae and Elasmosauridae. The occurrence of Cryptoclididae is reported from the Antarctic region for the first time. The taxon represents a new genus and species, based on a skull and associated cervical vertebrae. The long, slender and delicate teeth may have formed a ‘trapping’ device that enabled cryptoclidids to feed on… 
New elasmosaurids (Sauropterygia, Plesiosauria) from the Late Cretaceous of the Magallanes Basin, Chilean Patagonia: Evidence of a faunal turnover during the Maastrichtian along the Weddellian Biogeographic Province
Several Upper Cretaceous plesiosaur specimens recovered from southernmost Chile are described here. These were collected from upper levels of the Dorotea Formation exposed on three different
Cretaceous Antarctic plesiosaurs: stratigraphy, systematics and paleobiogeography
The last twenty million years (Maastrichtian–Santonian) of Southern Hemisphere plesiosaur history is especially well recorded in the Weddellian Province (Patagonia; Western Antarctica and New
A LATE CRETACEOUS CALLORHYNCHID (CHONDRICHTHYES, HOLOCEPHALI) FROM SEYMOUR ISLAND, ANTARCTICA
The discovery of chimaeroid tooth plates in late Cretaceous deposits on Seymour Island, Antarctica extends the fossil record of the chimaeriform holocephalian fishes and helps to elucidate their
A reappraisal of the Late Cretaceous Weddellian plesiosaur genus Mauisaurus Hector, 1874
TLDR
A re-assessment of the most complete specimen previously assigned to Mauisaurus suggests it is a typical long-necked elasmosaurid closely comparable to Tuarangisaurus keyesi Wiffen and Moisley, 1986.
Cryptoclidid Plesiosaurs (Sauropterygia, Plesiosauria) from the Upper Jurassic of the Atacama Desert
ABSTRACT This study presents the first plesiosaurs recovered from the Jurassic of the Atacama Desert that are informative at the genus level. One specimen is represented by an articulated axial
The oldest plesiosaur (Reptilia, Sauropterygia) from Antarctica
Antarctic plesiosaurs are known from the Upper Cretaceous López de Bertodano and Snow Hill Island formations (Campanian to upper Maastrichtian), which crop out within the James Ross Basin region of
Osteology of the Cryptocleidoid Plesiosaur Tatenectes laramiensis, with Comments on the Taxonomic Status of the Cimoliasauridae
TLDR
New fossil material of Tatenectes is described, and the phylogenetic position of this genus is reevaluate based on all known material, with TatenECTes as being most closely related to the Oxford Clay taxon Kimmerosaurus.

Plesiosaur Ancestors from the Upper Permian of Madagascar
TLDR
The nature of the Upper Permian sediments in Madagascar and the tectonic environment of their deposition indicate accumulation in deep rift valleys, some parts of which were open to the sea, and the presence of oolites replaced with collophane suggests a rich phosphate source such as deep marine upwellings.

The skull of a new eosuchian reptile from the Lower Jurassic of South Wales
TLDR
Comparison with earlier non-archosaurian diapsid reptiles indicates that Gephyrosaurus is a member of the Eosuchia, an infraclass of the subclass Diapsida, and was a small insectivore with large eyes and good hearing.
The Nothosaur Pachypleurosaurus and the Origin of Plesiosaurs
TLDR
It is concluded that the transition between primitive terrestrial diapsids and plesiosaurs occurred via a succession of changes in patterns of aquatic locomotion and Pachypleurosaurus has the greatest degree of development of the anterior portion of the shoulder girdle, suggesting that the recovery stroke was of considerable importance.
