Journal of Anatomy, Volume 236, Issue 4, Page 630-659, April 2020., 2020 The skull of a well preserved specimen of Champsosaurus lindoei was computed tomography (CT) scanned to describe the cranial elements and comment on the putative choristoderan neomorphic bone. These data provide the first exhaustive description of a choristodere skull using CT scanning, and confirm the presence of the neomorphic bone lateral to the ...

A new phylogenetic hypothesis of Tanystropheidae (Diapsida, Archosauromorpha) and other “protorosaurs”, and its implications for the early evolution of stem archosaurs [PDF]
PeerJ, 2021 The historical clade “Protorosauria” represents an important group of archosauromorph reptiles that had a wide geographic distribution between the Late Permian and Late Triassic.

Do cladistic and morphometric data capture common patterns of morphological disparity? [PDF]
, 2015 The distinctly non-random diversity of organismal form manifests itself in discrete clusters of taxa that share a common body plan. As a result, analyses of disparity require a scalable comparative framework.

Post-natal parental care in a Cretaceous diapsid from northeastern China [PDF]
, 2015 Post-natal parental care seems to have evolved numerous times in vertebrates. Among extant amniotes, it is present in crocodilians, birds, and mammals. However, evidence of this behavior is extremely rare in the fossil record and is only reported for two

The palatal dentition of tetrapods and its functional significance [PDF]
, 2017 The presence of a palatal dentition is generally considered to be the primitive condition in amniotes, with each major lineage showing a tendency toward reduction. This study highlights the variation in palatal tooth arrangements and reveals clear trends

Growth patterns, sexual dimorphism, and maturation modeled in Pachypleurosauria from Middle Triassic of central Europe (Diapsida: Sauropterygia) [PDF]
Fossil Record, 2018 Bone tissue, microanatomy, and growth are studied in humeri of the pachypleurosaurs Dactylosaurus from the early Anisian of Poland and of aff. Neusticosaurus pusillus from the Lettenkeuper (early Ladinian) of southern Germany.

The youngest South American rhynchocephalian, a survivor of the K/Pg extinction [PDF]
, 2014 Rhynchocephalian lepidosaurs, though once widespread worldwide, are represented today only by the tuatara (Sphenodon) of New Zealand. After their apparent early Cretaceous extinction in Laurasia, they survived in southern continents.
