Plesiosaurs are one of the common groups of aquatic reptiles in the Mesozoic, which mainly lived in marine environments. Freshwater plesiosaurs are rare in the world, especially from the Jurassic. The present paper reports the first freshwater plesiosaur, represented by four isolated teeth from the Middle Jurassic fluviolacustrine strata of Qingtujing area, Jinchang City, Gansu Province, Northwest China. These teeth are considered to come from one individual. The comparative analysis of the…

The Kap Stewart Group (Rhaetian‐Sinemurian, Triassic–Early Jurassic) of the Jameson Land Basin in central East Greenland has traditionally been regarded as a strictly continental unit with delta and
Ecophysiological steps of marine adaptation in extant and extinct non‐avian tetrapods
TLDR
Ecophysiological features in extant non-avian marine tetrapods representing 31 marine colonizations are reviewed to test whether there is a common pattern across higher taxonomic groups, such as mammals and reptiles, to reconstruct the evolutionary history of marine adaptation.

PRELIMINARY DESCRIPTION AND PHYLOGENETIC POSITION OF A NEW PLESIOSAUR (REPTILIA: SAUROPTERYGIA) FROM THE TOARCIAN OF HOLZMADEN, GERMANY
TLDR
A phylogenetic analysis places Plesiopterys as the sister group of the Plesiosauroidea, and as such the taxon is the most basal taxon yet known on the branch leading to this major clade.
Early Jurassic plesiosaurs from Australia
Remains of plesiosaurs (aquatic reptiles of the suborder Plesiosauria, order Sauropterygia) are known from Cretaceous sediments in every continent1, including Antarctica2. Jurassic plesiosaurs, by
Reassessment of the Lower Cretaceous (Barremian) pliosauroid Leptocleidus superstes Andrews, 1922 and other plesiosaur remains from the nonmarine Wealden succession of southern England
TLDR
To test the competing hypotheses, L. superstes together with all closely related species were rescored into the most comprehensive published phylogenetic data sets of Plesiosauria and Pliosauroidea and confirmed placement within either Rhomaleosauridae sensu stricto, or a discrete ‘leptocleidoid’ clade.
