The origin and early evolution of Sauria: reassessing the permian Saurian fossil record and the timing of the crocodile-lizard divergence.

open access: yesPLoS ONE, 2014
Sauria is the crown-group of Diapsida and is subdivided into Lepidosauromorpha and Archosauromorpha, comprising a high percentage of the diversity of living and fossil tetrapods.

THE FIRST ITALIAN SPECIMEN OF AUSTRIADACTYLUS CRISTATUS (DIAPSIDA, PTEROSAURIA) FROM THE NORIAN (UPPER TRIASSIC) OF THE CARNIC PREALPS

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2009
The Triassic pterosaur Austriadactylus cristatus is reported for the first time from the Norian (Upper Triassic) of north-eastern Italy. It is only the second specimen of this taxon and provides new information on the mandibular dentition, cranium and ...

MicroRNAs support a turtle + lizard clade

open access: yes, 2011
Despite much interest in amniote systematics, the origin of turtles remains elusive. Traditional morphological phylogenetic analyses place turtles outside Diapsida—amniotes whose ancestor had two fenestrae in the temporal region of the skull (among the ...

A new, exceptionally preserved juvenile specimen of Eusaurosphargis dalsassoi (Diapsida) and implications for Mesozoic marine diapsid phylogeny

open access: yesScientific Reports, 2017
Recently it was suggested that the phylogenetic clustering of Mesozoic marine reptile lineages, such as thalattosaurs, the very successful fish-shaped ichthyosaurs and sauropterygians (including plesiosaurs), among others, in a so-called ‘superclade’ is ...

Skull shape and feeding strategy in Sphenodon and other Rhynchocephalia (Diapsida: Lepidosauria) [PDF]

open access: yesJournal of Morphology, 2008
AbstractThe Rhynchocephalia are a group of small diapsid reptiles that were globally distributed during the early Mesozoic. By contrast, the only extant representatives, Sphenodon punctatus and S. guntheri (Tuatara), are restricted to New Zealand off‐shore islands.

Transitional fossils and the origin of turtles

open access: yes, 2010
The origin of turtles is one of the most contentious issues in systematics with three currently viable hypotheses: turtles as the extant sister to (i) the crocodile–bird clade, (ii) the lizard–tuatara clade, or (iii) Diapsida (a clade ...

A Late Campanian sphenodontid (Reptilia, Diapsida) from northern Patagonia

open access: yesComptes Rendus Palevol, 2005
Abstract The fossil record of sphenodontids in the Southern Hemisphere is much longer than in Laurasia, where they became extinct after Early Cretaceous times. Recent works demonstrated the persistence of at least eilenodontine sphenodontids until the ‘mid’-Cretaceous of Patagonia.

A REVISION OF LANGOBARDISAURUS ROSSII BIZZARINI AND MUSCIO, 1995 FROM THE LATE TRIASSIC OF FRIULI (ITALY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2007
A nearly complete but poorly preserved amniote from the Middle-Upper Norian of Friuli (NE Italy), previously attributed to a new species of the protorosaur genus Langobardisaurus (L. rossii Bizzarini & Muscio, 1995), is re-described.
