The vertebrate lineages that would shape Mesozoic and Cenozoic terrestrial ecosystems originated across Triassic Pangaea1–11. By the Late Triassic (Carnian stage, ~235 million years ago), cosmopolitan ‘disaster faunas’ (refs. 12–14) had given way to highly endemic assemblages12,13 on the supercontinent. Testing the tempo and mode of the establishment of this endemism is challenging—there were few geographic barriers to dispersal across Pangaea during the Late Triassic. Instead… 

Climatic controls on the ecological ascendancy of dinosaurs

A New Rhynchosaur Taxon from the Popo Agie Formation, WY: Implications for a Northern Pangean Early-Late Triassic (Carnian) Fauna

New discoveries in the lower Popo Agie Formation (lower carbonate unit) of central Wyoming necessitated a reevaluation of USNM 494329 from the same unit, the only known hyperodapedontine rhynchosaur

Statistical evaluation of character support reveals the instability of higher-level dinosaur phylogeny

It is concluded that early dinosaur relationships are unlikely to be resolved without fundamental changes to both the quality of available datasets and the techniques used to analyze them.

The dinosaurian femoral head experienced a morphogenetic shift from torsion to growth along the avian stem

The evolutionary history of morphogenesis of the proximal end of the femur from early archosaurs to crown birds is reconstructed, inferring that the medial overhang of the dinosaur femoral head was initially acquired by torsion, which was then superseded by mediad growth.

The absence of an invasive air sac system in the earliest dinosaurs suggests multiple origins of vertebral pneumaticity

The origin of the air sac system present in birds has been an enigma for decades. Skeletal pneumaticity related to an air sac system is present in both derived non-avian dinosaurs and pterosaurs. But

Dynamic biogeographic models and dinosaur origins

ABSTRACT A comprehensive analysis of early dinosaur relationships raised the possibility that the group may have originated in Laurasia (Northern Hemisphere), rather than Gondwana (Southern

Climatically driven biogeographic provinces of Late Triassic tropical Pangea

It is hypothesized that variations in the climatic expression of astronomical forcing produced latitudinal climatic zones that sorted terrestrial vertebrate taxa into distinct biogeographic provinces tracking latitude, not geographic position, as the proto-North American plate translated northward.

The origin and early evolution of dinosaurs

The oldest unequivocal records of Dinosauria were unearthed from Late Triassic rocks accumulated over extensional rift basins in southwestern Pangea, and the group achieved a nearly global distribution by the latest Triassic, especially with the radiation of saurischian groups such as “prosauropods” and coelophysoids.

The oldest dinosaur? A Middle Triassic dinosauriform from Tanzania

Nyasasaurus possesses a unique combination of dinosaur character states and an elevated growth rate similar to that of definitive early dinosaurs, demonstrating that the initial dinosaur radiation occurred over a longer timescale than previously thought and that dinosaurs are better understood as part of a larger Middle Triassic archosauriform radiation.

Northward dispersal of dinosaurs from Gondwana to Greenland at the mid-Norian (215–212 Ma, Late Triassic) dip in atmospheric pCO2

Significance Sharply contrasting climate zonations under high atmospheric pCO2 conditions can exert significant obstacles to the dispersal of land vertebrates across a supercontinent. This is argued

Vertebrate Succession in the Ischigualasto Formation

ABSTRACT The Upper Triassic (Carnian—Norian) Ischigualasto Formation has yielded a diverse vertebrate fauna that records the initial phase of dinosaur evolution. Radioisotopic dates from ash layers

Enigmatic dinosaur precursors bridge the gap to the origin of Pterosauria

It is demonstrated that lagerpetids—a group of cursorial, non-volant dinosaur precursors—are the sister group of pterosaurs, sharing numerous synapomorphies across the entire skeleton, substantially shortening the temporal and morphological gap between the oldest pterosaurus and their closest relatives and simultaneously strengthens the evidence that pter dinosaurs belong to the avian line of archosaurs.

Supradapedon revisited: geological explorations in the Triassic of southern Tanzania

A field trip conducted in July 2015 to the vicinities of Tunduru and Msamara, Ruvuma Region, Tanzania, in search of fossil discoveries was unsuccessful, but the geological mapping conducted during the trip improved knowledge of the deposition systems of the southern margin of the Selous Basin during the Triassic, allowing tentative correlations to its central part and to neighbouring basins.

Gnathovorax cabreirai: a new early dinosaur and the origin and initial radiation of predatory dinosaurs

An ecomorphological analysis employing dental traits indicates that herrerasaurids occupy a particular area in the morphospace of faunivorous dinosaurs, which partially overlaps the area occupied by post-Carnian theropods, indicating that her rerasaurid dinosaurs preceded the ecological role that later would be occupied by large to medium-sized theropoda.
