TL;DR: New fossils from the Early Triassic sauropterygian Lariosaurus sanxiaensis and associated reptile fauna recovered from South China are presented and phylogenetic analysis places L.sanxiaensis as a basal nothosaur.
Abstract: The timing and pattern of biotic recovery from the Permo-Triassic Mass Extinction remains elusive. Here we report new material of the Early Triassic sauropterygian Lariosaurus sanxiaensis and associated fauna from the Jialingjiang Formation in Hubei Province, South China. Phylogenetic analysis based on a novel data matrix of sauropterygians recognizes L. sanxiaensis as a basal nothosaur. Stratigraphic congruence analysis shows that the new phylogenetic consensus tree matches to the stratigraphic distribution of sauropterygians very well. The diversified reptilian fauna and inferred simple food web in the Nanzhang-Yuan’an fauna where L. sanxiaensis was discovered suggest that the Triassic biotic recovery adopted a top-down pattern, in contrast to the prevailing view. Comparison with the Middle Triassic Luoping biota from the same carbonate platform suggests that the Triassic biotic recovery is delayed and healthy ecosystems were not established until the Middle Triassic in South China. Qiang Li & Jun Liu present new fossils from the Early Triassic sauropterygian Lariosaurus sanxiaensis and associated reptile fauna recovered from South China. Their phylogenetic analysis places L. sanxiaensis as a basal nothosaur.

TL;DR: The first Triassic sauropterygian to be described from China was Keichousaurus hui (Young, 1958) found in Xingyi, Guizhou Province.
Abstract: The first Triassic sauropterygian to be described from China was Keichousaurus hui (Young, 1958) found in Xingyi, Guizhou. Shingyisaurus unexpectus, another sauropterygian found in Xingyi, Was referred to the Simosauridae by Young (1965). It was identified as Nothosaurus or a closely related gnus, and the name Shingyisaurus unexpectus was considered a nomen dubium (Rieppel, 1998). Here we report a well-preserved specimen from Xingyi, Guizhou Province. It represents the first undoubted specimen and a new species of Lariosaurus ever found outside western Tethyan faunal province.

TL;DR: In this paper, the anatomy of Lariosaurus xingyiensis (IVPP V 11866) from the Middle Triassic of southern China is described in detail, which ranks among the best preserved of its genus.
Abstract: The anatomy of a specimen of Lariosaurus xingyiensis (IVPP V 11866) from the Middle Triassic of southern China is described in detail. The specimen ranks among the best preserved of its genus. Specimen IVPP V 11866 is the first unequivocal record of the occurrence of Lariosaurus in the Triassic of southern China, indeed the first record of this genus outside the western Tethyan province. A cladistic analysis using parsimony found IVPP V 11866 to represent the sister taxon of Lariosaurus calcagnii from the Middle Triassic of the southern Alps. This result reinforces the signal for western Tethyan paleobiogeographic relationships of the Triassic marine reptiles from southern China.

TL;DR: In this paper, the taxonomic position of the genus Lariosaurus and Ceresiosaurus was rewieve by means of cladistic analysis and discussed some paleobiological and paleoecological aspects.
Abstract: The Ceresiosaurus genus was a Nothosauria group, that inhabited in the more meridional Alpine basins of the Tethys sea during Ladinian age (Middle Triassic). In this paper, we to describe the first finding of this genus in the Iberian peninsula, in Mont-ral- Alcover (Tarragona), an outcrop with abundant fauna and flora but where dolomitization destroyed all original skeletal material. We rewieve the taxonomic position of the genus Lariosaurus and Ceresiosaurus to belong to Lariosauridae branch by means of cladistic analysis and we discuss some paleobiological and paleoecological aspects.
