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

Growth patterns, sexual dimorphism, and maturation modeled in Pachypleurosauria from Middle Triassic of central Europe (Diapsida: Sauropterygia) [PDF]
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.

Intraorganismal Homology, Character Construction, and the Phylogeny of Aetosaurian Archosaurs (Reptilia, Diapsida) [PDF]
Character construction, the methods by which characters and character states are produced from observations of variation, is a crucial but poorly understood step in phylogenetic analysis. Alternative approaches are used in practice, but there has been relatively little investigation of their theoretical bases and analytical consequences.

EVIDENCES FOR A SEMI AQUATIC LIFE STYLE IN THE TRIASSIC DIAPSID REPTILE TANYSTROPHEUS
The paleoecology of the bizarre, long-necked tanystropheid diapsid Tanystropheus from the Middle and Late Triassic of Western and Eastern Tethys has been debated since the first discoveries.

The neodiapsid Thadeosaurus colcanapi from the upper Permian of Madagascar
Abstract The enigmatic neodiapsid Thadeosaurus colcanapi (Lower Sakamena Formation, southwestern Madagascar), sole species of the genus Thadeosaurus, is revised here. The attribution of 12 of the 21 referred specimens is confirmed, spanning all ontogenetic stages, and the anatomy of Thadeosaurus is redescribed in detail with comments on ontogenetical ...

A new diapsid reptile is described from the locality of Cene (Seriana Valley, near Bergamo, Lombardy, Northern ltaly) from an outcrop of the Calcare di Zorzino (Zorzino Limestone) Formation (Middle Norian, Late Triassic).
