ABSTRACT Cryptocleidoid plesiosaurs from the Upper Jurassic are well known from the Oxford Clay (Callovian) of the United Kingdom. The plesiosaurs of the nearly coeval Sundance Formation (Oxfordian) of North America are poorly known, but are thought to include two cryptocleidoid taxa: Pantosaurus striatus and Tatenectes laramiensis. Here we present two specimens recently recovered from the Bighorn Basin of Wyoming. The first specimen comprises three articulated adult cervical vertebrae and… 
A New Skeleton of the Cryptoclidid Plesiosaur Tatenectes laramiensis Reveals a Novel Body Shape Among Plesiosaurs
TLDR
It is hypothesized that Tatenectes had a dorsoventrally compressed, oblate spheroid body shape, with a high skeletal mass concentration in the ventral elements, perhaps allowing access to above normal wave base, inshore environments in the shallow Sundance Seaway.
OF A PLESIOSAUR FROM THE SUNDANCE FORMATION ( JURASSIC ) , HOT SPRINGS COUNTY , WYOMING , AND IMPLICATIONS FOR THE PALEOBIOLOGY OF CRYPTOCLEIDID PLESIOSAURS
The discovery of a semi articulated partial skeleton of a plesiosaur from the Redwater Shale Member of the Sundance Formation of the Bighorn Basin, Wyoming, may represent the most complete
Anatomy of Colymbosaurus megadeirus (Reptilia, Plesiosauria) from the Kimmeridge Clay Formation of the U.K., and High Diversity Among Late Jurassic Plesiosauroids
TLDR
Substantial differences between the atlas-axis complexes and cervical vertebrae of Kimmerosaurus langhami, ‘Plesiosaurus’ manselii, C. megadeirus, and specimens referred here to cf.
Osteology and Relationships of Colymbosaurus Seeley, 1874, Based on New Material of C. svalbardensis from the Slottsmøya Member, Agardhfjellet Formation of Central Spitsbergen
TLDR
A phylogenetic analysis recovers a monophyletic and well-supported Colymbosaurus, and confirms that this species is not synonymous with other described Slottsmøya Member plesiosauroids, demonstrating considerable diversity of the clade at high latitudes close to the Jurassic-Cretaceous boundary.
Postcranial elements of "Maledictosuchus riclaensis" (Thalattosuchia) from the Middle Jurassic of Spain
Maledictosuchus riclaensis is a metriorhynchid crocodylomorph from the Callovian (Middle Jurassic) of Ricla (Spain). It is the most basal member of the Rhacheosaurini Tribe; it has recently been
Osteology of Aristonectes quiriquinensis (Elasmosauridae, Aristonectinae) from the Upper Maastrichtian of Central Chile
ABSTRACT The upper Maastrichtian elasmosaurid plesiosaur Aristonectes quiriquinensis from central Chile is here redescribed following further preparation of the holotype. New cranial characters
MORPHOLOGY OF THE CAUDAL VERTEBRAE IN RHOMALEOSAURUS ZETLANDICUS AND A REVIEW OF THE EVIDENCE FOR A TAIL FIN IN PLESIOSAURIA
TLDR
The osteology of the tail is described and two morphological characteristics are interpreted as evidence for a caudal fin in Rhomaleosaurus, which corroborates evidence from other plesiosaurian taxa and suggests that a caUDal fin may have been widespread among plesioaurians, with implications for locomotion and behavior.
Palaeoecology of the marine reptiles of the Redwater Shale Member of the Sundance Formation (Jurassic) of central Wyoming, USA
Abstract The Redwater Shale Member (Oxfordian) of the Sundance Formation was deposited in the foreland basin of the Cordillera during the last and largest marine transgression of the Jurassic in
THE OCCURRENCE OF VERTEBRATE AND INVERTEBRATE FOSSILS IN A SEQUENCE STRATIGRAPHIC CONTEXT: THE JURASSIC SUNDANCE FORMATION, BIGHORN BASIN, WYOMING, U.S.A
ABSTRACT Previous studies of the sequence stratigraphic distribution of fossils have focused on the record of relatively abundant marine invertebrates. Only a handful of studies have examined how
Faunal turnover of marine tetrapods during the Jurassic–Cretaceous transition
TLDR
The observation of discordant extinction patterns in other marine tetrapod groups such as ichthyosaurs and marine crocodylomorphs suggests that clade‐specific factors may have been more important than overarching extrinsic drivers of faunal turnover during the Jurassic–Cretaceous boundary interval.

Current Taxonomic Status of the Plesiosaur Pantasaurus Striatus from the Upper Jurassic Sundance Formation, Wyoming
TLDR
The taxon MuraenQSOUrus reedii Mebl 1912 is shown to be a junior synonym of Pantowurus striatus and it is believed that Panlosaurus striatus is a valid taxon.

Evidence of Pachyostosis in the Cryptocleidoid Plesiosaur Tatenectes laramiensis from the Sundance Formation of Wyoming
In this paper we present evidence for pachyostosis in the cryptocleidoid plesiosaur Tatenectes laramiensis Knight, 1900 (O’Keefe and Wahl, 2003a). Pachyostosis is not common in plesiosaurs and is
A Cladistic Analysis and Taxonomic Revision of the Plesiosauria (Reptilia: Sauropterygia)
TLDR
The Plesiosauria is found to by polyphyletic due to the inclusion of the Polycotylidae; this second clade is instead a member of the Plesiosauroidea, and thus more closely related to elasmosaurs than to other ‘pliosaurs’.
A Plesiosaur Containing an Ichthyosaur Embryo as Stomach Contents from the Sundance Formation of the Bighorn Basin, Wyoming
TLDR
The embryo was discovered in close association with the abdomen of an articulated partial plesiosaur skeleton, and several lines of evidence support the interpretation of the embryo as plesioaur stomach contents, and is the first Jurassic ichthyosaur embryo from North America.
