The Late Triassic pseudosuchian Revueltosaurus callenderi and its implications for the diversity of early ornithischian dinosaurs
TLDR
Dental characters previously used to place Revueltosaurus within the Ornithischia evolved convergently among other archosaur taxa, and cannot be used to diagnose ornithischian dinosaur teeth. Expand
High-resolution U-Pb ages from the Upper Triassic Chinle Formation (New Mexico, USA) support a diachronous rise of dinosaurs
Abstract Though the Late Triassic preserves major paleoenvironmental fluctuations and is key for understanding the evolution of Mesozoic and modern terrestrial ecosystems, comparisons of LateExpand

TECOVASUCHUS CHATTERJEEI, A NEW AETOSAUR (ARCHOSAURIA: STAGONOLEPIDIDAE) FROM THE TECOVAS FORMATION (CARNIAN, UPPER TRIASSIC) OF TEXAS
Abstract A new aetosaur, Tecovasuchus chatterjeei gen. et sp. nov., from the Upper Triassic (middle or upper Carnian) Tecovas Formation of Texas is described, based primarily on osteoderms fromExpand
A new aetosaur from the Upper Triassic Chinle Formation of the Eagle Basin, Colorado, USA
Abstract A small aetosaur skull and skeleton and referred material from the Chinle Formation, Eagle Basin of Colorado, USA, is described as a new taxon, Stenomyti huangae gen. et sp. nov,Expand
Revised Lithostratigraphy of the Sonsela Member (Chinle Formation, Upper Triassic) in the Southern Part of Petrified Forest National Park, Arizona
TLDR
These investigations demonstrate the neglected necessity of walking out contacts and mapping when constructing lithostratigraphic models, and providing UTM coordinates and labeled photographs for all measured sections. Expand
Aetosauria: a clade of armoured pseudosuchians from the Upper Triassic continental beds
TLDR
Aetosauria is a clade of obligately quadrupedal, heavily armoured pseudosuchians known from Upper Triassic strata on every modern continent except Australia and Antarctica, and there is increasing evidence that at least some aetosaurs relied on invertebrates and/or small vertebrates as a food source. Expand
A taxonomic and biostratigraphic re-evaluation of the Post Quarry vertebrate assemblage from the Cooper Canyon Formation (Dockum Group, Upper Triassic) of southern Garza County, western Texas
ABSTRACT The Post Quarry, within the lower part of the type section of the Upper Triassic Cooper Canyon Formation in southern Garza County, western Texas, contains a remarkably diverse vertebrateExpand
