Osteohistology of the Maastrichtian, small-bodied elasmosaurid Kawanectes lafquenianum (Sauropterygia; Plesiosauria). [PDF]
J AnatThe present contribution brings new osteohistological information on the postcranial bones of Kawanectes lafquenianum and shed some light on Plesiosauria microanatomy and microstructure. The bone architecture shows variability between forelimbs and hindlimbs.

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.

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 ...

Foramina in plesiosaur cervical centra indicate a specialized vascular system [PDF]
Fossil Record, 2017 The sauropterygian clade Plesiosauria arose in the Late Triassic and survived to the very end of the Cretaceous. A long, flexible neck with over 35 cervicals (the highest number of cervicals in any tetrapod clade) is a synapomorphy of Pistosauroidea ...

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
