Osteohistology of the Maastrichtian, small-bodied elasmosaurid Kawanectes lafquenianum (Sauropterygia; Plesiosauria). [PDF]
J AnatAbstractPlesiosauria is a clade of marine reptiles that thrived from the Late Triassic to the end of the Cretaceous. Among plesiosaurs, the elasmosaurids are particularly notable for their diverse body sizes. Small‐sized specimens of Kawanectes lafquenianum exhibit fully closed neuro‐central sutures indicating skeletal maturity. To independently assess

Recognising and quantifying the evolution of skeletal paedomorphosis in Plesiosauria [PDF]
Fossil Record, 2023 Plesiosaurs are one of the longest-ranging tetrapod groups in the Mesozoic and underwent a major adaptive radiation in the Late Triassic/Early Jurassic, so they are an ideal clade to study the long-term implications and deep-time evolution of specific ...

A reappraisal of Polyptychodon (Plesiosauria) from the Cretaceous of England [PDF]
PeerJ, 2016 Pliosauridae is a globally distributed clade of aquatic predatory amniotes whose fossil record spans from the Lower Jurassic to the Upper Cretaceous. However, the knowledge of pliosaurid interrelationships remains limited.

An unusual early-diverging plesiosauroid from the Lower Jurassic Posidonia Shale of Holzmaden, Germany [PDF]
PeerJThe lower Toarcian Posidonia Shale at Holzmaden, Southwest Germany, has yielded some of the most remarkable Lower Jurassic marine tetrapod specimens, including five plesiosaur taxa identified from nearly complete skeletons.

Hematological convergence between Mesozoic marine reptiles (Sauropterygia) and extant aquatic amniotes elucidates diving adaptations in plesiosaurs [PDF]
PeerJ, 2019 Plesiosaurs are a prominent group of Mesozoic marine reptiles, belonging to the more inclusive clades Pistosauroidea and Sauropterygia. In the Middle Triassic, the early pistosauroid ancestors of plesiosaurs left their ancestral coastal habitats and ...

A new plesiosaur from the Lower Jurassic of Portugal and the early radiation of Plesiosauroidea [PDF]
Acta Palaeontologica Polonica, 2021 A new plesiosaur partial skeleton, comprising most of the trunk and including axial, limb, and girdle bones, was collected in the lower Sinemurian (Coimbra Formation) of Praia da Concha, near São Pedro de Moel in central west Portugal.

The osteology, taxonomy, and phylogenetic affinities of the Early Jurassic plesiosaur Lusonectes sauvagei [PDF]
PeerJThe transition from the Early to the Middle Jurassic was marked by significant restructuring of plesiosaur communities. While knowledge of the earliest Middle Jurassic plesiosaurs is generally limited, Toarcian plesiosaur occurrences are abundant, though

Estimating the evolutionary rates in mosasauroids and plesiosaurs: discussion of niche occupation in Late Cretaceous seas [PDF]
PeerJ, 2020 Observations of temporal overlap of niche occupation among Late Cretaceous marine amniotes suggest that the rise and diversification of mosasauroid squamates might have been influenced by competition with or disappearance of some plesiosaur taxa.
