High diversity, low disparity and small body size in plesiosaurs (Reptilia, Sauropterygia) from the Triassic-Jurassic boundary. [PDF]
PLoS ONE, 2012 Invasion of the open ocean by tetrapods represents a major evolutionary transition that occurred independently in cetaceans, mosasauroids, chelonioids (sea turtles), ichthyosaurs and plesiosaurs.

A basal elasmosaurid plesiosaur from the upper Albian– lower Cenomanian? Cambridge Greensand
Acta Palaeontologica PolonicaAn historical indeterminate elasmosaurid specimen CAMSM X50356 (CAMSM = Sedgwick Museum) collected during the 19th century is described. The specimen comes from the Cenomanian Cambridge Greensand although the possibility of an Albian–lower Cenomanian age

Pseudosuchian thermometabolism: A review of the past two decades
The Anatomical Record, Volume 308, Issue 2, Page 315-341, February 2025.Abstract Pseudosuchia, one of the two main clades of Archosauria, is today only represented by some 20 extant species, the crocodilians, representing only a fraction of its extinct diversity. Extant crocodilians are ectotherms but present morphological and anatomical features usually associated with endothermy.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals
Ecology and Evolution, Volume 14, Issue 9, September 2024.Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

FIRST RECORD OF SIMOSAURUS (SAUROPTERYGIA, NOTHOSAUROIDEA) FROM THE CARNIAN (LATE TRIASSIC) OF ITALY
Rivista Italiana di Paleontologia e Stratigrafia, 2008 The nothosauroid sauropterygian Simosaurus is reported for the first time both from Italy and from the early Carnian (earliest Late Triassic). Diagnostic dorsal neural arches and clavicles as well dorsal ribs have been collected in the Rio dal Lago ...

Evolutionary implications of the divergent long bone histologies of Nothosaurus and Pistosaurus (Sauropterygia, Triassic) [PDF]
BMC Evolutionary Biology, 2013 Eosauropterygians consist of two major clades, the Nothosauroidea of the Tethysian Middle Triassic (e.g., Nothosaurus) and the Pistosauroidea. The Pistosauroidea include rare Triassic forms (Pistosauridae) and the Plesiosauria of the Jurassic and Cretaceous. Long bones of Nothosaurus and Pistosaurus from the Muschelkalk (Middle Triassic) of Germany and

PECULIAR PRESERVATION OF A JUVENILE PACHYPLEUROSAURID FROM BESANO (ITALY)
Rivista Italiana di Paleontologia e Stratigrafia, 2006 A small pachypleurosaurid collected in the Besano area of Italy, is described. A comparative analysis of size and proportions with other pachipleurosaurids suggest it represents a juvenile specimen of Neusticosaurus pusillus.
