A new eosauropterygian (Diapsida, Sauropterygia) from the Triassic of China
Journal of Vertebrate Paleontology, 2012ABSTRACT A new Middle Triassic sauropterygian, Qianxisaurus chajiangensis, gen. et sp. nov., is described on the basis of a skeleton from the Zhuganpo Member (Ladinian) of the Falang Formation, Xingyi, southwestern Guizhou Province, China. It is primarily characterized by a premaxilla with eight teeth, marginal teeth with a slightly constricted ...

Peculiarities of the Structure and Locomotor Function of the Tail in Sauropterygia
Biology Bulletin, 2019Among ancient and modern marine reptiles, several structural types of the locomotor apparatus were or are present, supporting different styles of swimming. Ichthyosaurs, mosasaurs, saltwater crocodiles, and representatives of many other groups swam or swim with horizontal undulations of the body primarily using the tail with a vertical caudal fin.

The pachypleurosaurid Dactylosaurus schroederi (Diapsida: Sauropterygia)
Canadian Journal of Earth Sciences, 1985Redescription of the small pachypleurosaurid nothosaur Dactylosaurus schroederi Nopsca, 1928, from the Muschelkalk of Upper Silesia (Gorny Slask), Poland, indicates that it closely resembles Neusticosaurus but differs from the latter in a number of features. The forelimb, especially the antebrachium, is very gracile.

The evolution of plesiosaur and pliosaur morphotypes in the Plesiosauria (Reptilia: Sauropterygia)
Paleobiology, 2002The dichotomy between short-necked, large-headed “pliosaurs” and long-necked, small-headed “plesiosaurs” has formed the basis of plesiosaur taxonomy for over one hundred years. Recent work has cast doubt on the taxonomic validity of this dichotomy, suggesting that the pliosaur morphotype may have evolved independently in more than one clade. This paper

The cranial anatomy of Chinese placodonts and the phylogeny of Placodontia (Diapsida: Sauropterygia)
2015Placodonts are Triassic marine reptiles that inhabited the eastern and western margins of the Tethys Ocean (modern South China and Europe/Middle East). Although the crania of European taxa are relatively well understood, those of Chinese taxa have not been extensively studied, and most of them have not been incorporated into a comprehensive phylogeny ...

Historical Biology, 2013
Preparation of the holotype specimen of Bobosaurus forojuliensis, a large sauropterygian from the lower Carnian of northeastern Italy, revealed new morphological data relevant in establishing its phylogenetic affinities among pistosauroid taxa and its relationships with plesiosaurians. Inclusion of B. forojuliensis in two phylogenetic analyses focusing,
