The anatomy of the saurischian dinosaurStaurikosaums pricei Colbert from the Santa Maria Formation (Middle or Upper Triassic) of Rio do Sul, Brazil is redescribed.Staurikosaurus has 9 (or possibly 10) short cervicals, 15 dorsals and 2 sacral vertebrae, a modified brachyiliac pelvic girdle and an elongate hindlimb with the tibia longer than the femur.The new family Staurikosauridae is erected, the Herrerasauridae is redefined, and both families are considered to be Saurischia incertae sedis.

A new herrerasaurid (Dinosauria, Saurischia) from the Upper Triassic Ischigualasto Formation of northwestern Argentina
TLDR
The presence of Sanjuansaurus at the base of the Ischigualasto Formation, along with other dinosaurs such as Herrerasaurus, Eoraptor, Panphagia, and Chromogisaurus suggests that saurischian dinosaurs in southwestern Pangea were already widely diversified by the late Carnian rather than increasing in diversity across the Carnian-Norian boundary.
The anatomy and phylogenetic position of the Triassic dinosaur Staurikosaurus pricei Colbert, 1970
TLDR
The phylogenetic position of S. pricei is constrained by that of its sister taxon H. ischigualastensis, which is known from much more complete material, and the absence of some characters observed in the clades Theropoda and Sauropodomorpha suggests that S.pricei is not a member of Eusaurischia.
A new poposaurid from the Upper Triassic of Argentina
ABSTRACT The Poposauridae are a group of Middle to Late Triassic rauisuchian archosaurs that are the sister-group of the Crocodylomorpha. A new specimen from the Ischigualasto Formation (Carnian) of
Postosuchus, a New Thecodontian Reptile from the Triassic of Texas and the Origin of Tyrannosaurs
TLDR
Although Postosuchus exhibits many carnosaurian traits, its ankle joint is of \`crocodile-normal' pattern, which suggests its pseudosuchian affinity, and Tyrannosaurs probably evolved from poposaurids, as indicated by the correlation between skull, pelvis and ankle structure.
Cranial remains of Poposaurus gracilis (Pseudosuchia: Poposauroidea) from the Upper Triassic, the distribution of the taxon, and its implications for poposauroid evolution
TLDR
The character states of P. gracilis demonstrate that the evolution of bipedalism, the origin/loss of a dorsal ‘sail’ and the shift to an edentulous beak are complex in poposauroids.
New information on the systematics and postcranial skeleton of Herrerasaurus ischigualastensis (Ther
TLDR
New evidence supports this group as saurischian dinosaurs: the posterior process of the jugal is forked, a hyposphene-hypantrum articulation is present in dorsal vertebrae, the distal shaft of the ischium is rod-like, and six other saurishian synapomorphies are present.
A revision ofPoposaurus gracilis (Archosauria: Suchia) based on two new specimens from the Late Triassic of the southwestern U.S.A.
TLDR
The ilia of these new fossils are the first ofPoposaurus to preserve the complete preacetabular blade, which is long and “blade-like” rather than “paddle-shaped” as previously thought.
The tibia and tarsus in Herrerasauridae (Dinosauria, incertae sedis) and the origin and evolution of the dinosaurian tarsus
TLDR
It is concluded that Herrerasauridae retained the primitive tibiotarsal condition for Dinosauria, from which those of the Omithischia, Sauropodomorpha, and Theropoda were derived.
Anatomy and systematics of the sauropodomorph Sarahsaurus aurifontanalis from the Early Jurassic Kayenta Formation
TLDR
The phylogenetic analysis supports the conclusion that Sarahsaurus aurifontanalis is nested within the primarily Gondwanan clade Massospondylidae, while agreeing with previous analyses that the three North American sauropodomorphs do not themselves form an exclusive clade.
The Osteology and Phylogenetic Position of Luperosuchus fractus (Archosauria: Loricata) from the Latest Middle Triassic or Earliest Late Triassic of Argentina
TLDR
It is confirmed that Luperosuchus is a loricatan (composed mostly of the taxa classically termed as ‘rauisuchians’) using a well sampled phylogeny and find a close relationship with the other large southwestern Pangean forms, Prestosuchu chiniquensis and Saurosuchus galilei.

On the anatomy and relationships ofEfraasia diagnostica (Huene) n. gen., a prosauropod dinosaur (Reptilia: Saurischia) from the Upper Triassic of Germany
TLDR
The anatomy of Efraasia diagnostica is conservative and it was an ideal ancestor for the later and more specializedAnchisaurus polyzelus of North America.
On the origin of the sauropods and the classification of the Saurischia
TLDR
Re-examination of melanorosaurid material in South Africa shows that none is properly associated and that the proportions cannot be determined, and concepts of sauropodomorph phylogeny are incompatible with the stratigraphical position of the Melanorosauridae below the Thecodontosauridae (in South Africa).

Dinosaur Monophyly and a New Class of Vertebrates
TLDR
Evidence is presented that dinosaurs are a single, monophyletic group, and that the key advancements of endothermy and high exercise metabolism are justification for removing dinosaurs from the Reptilia and placing them with birds in a new class, the Dinosauria.
