ABSTRACT The problem of the origin of dinosaurs has historically had three dimensions. The first is the question of whether Dinosauria is monophyletic, and of its relationships to other archosaurs. This question was plagued from the beginning by a lack of relevant fossils, an historical burden of confusing taxonomic terms and a rudimentary approach to devising phylogenies. The second dimension concerns the functional and ecological adaptations that differentiated dinosaurs from other archosaurs… Expand
The precise temporal calibration of dinosaur origins
Using precise radioisotopic ages, it is demonstrated that the temporal gap between assemblages containing only dinosaur precursors and those with the first dinosaurs was 5–10 million years shorter than previously thought, suggesting that the origin of dinosaurs was a relatively rapid evolutionary event. Expand
Increases in sampling support the southern Gondwanan hypothesis for the origin of dinosaurs
Dinosaurs were ubiquitous in terrestrial ecosystems through most of the Mesozoic and are still diversely represented in the modern fauna in the form of birds. Recent efforts to better understand theExpand
The Origin and Early Radiation of Archosauriforms: Integrating the Skeletal and Footprint Record
Analysis of body size, as deduced from track size, suggests that archosauriform average body size did not change significantly from the Late Permian to the Early Triassic, and a survey of facies yielding both skeletal and track record indicate an ecological preference for inland fluvial (lacustrine) environments for early Archosauromorphs. Expand
A new hypothesis of dinosaur relationships and early dinosaur evolution
This study has found a sister-group relationship between Ornithischia and Theropoda (united in the new clade Ornithoscelida), with Sauropodomorpha and Herrerasauridae (as the redefined Saurischia) forming its monophyletic outgroup. Expand
Triassic sauropodomorph dinosaurs from South America: The origin and diversification of dinosaur dominated herbivorous faunas
Abstract Sauropodomorpha is the first major dinosaurian group that radiated during the Triassic. During this time the group underwent major changes in body plan, including the acquisition of featuresExpand
The age of transformation: the Triassic Period and the rise of today's land vertebrate fauna
The Triassic Period (about 251 to 200 million years ago on the most recent geological timescales) was revolutionary in two senses. First, faunal turnover among terrestrial tetrapods was greater, byExpand
Pisanosaurus mertii and the Triassic ornithischian crisis: could phylogeny offer a solution?
Abstract Two recent studies have independently recovered Pisanosaurus mertii – long thought to represent the oldest known member of Ornithischia – within Silesauridae. These finds are expanded uponExpand
Scelidosaurus harrisonii (Dinosauria: Ornithischia) from the Early Jurassic of Dorset, England: biology and phylogenetic relationships
A layer of keratinous scutes encased the skull of Scelidosaurus. The neurocranium and the associated principal sensory systems of this dinosaur are described. The cranial musculature isExpand
Phylogenetic reassessment of Pisanosaurus mertii Casamiquela, 1967, a basal dinosauriform from the Late Triassic of Argentina
The present analysis indicates that Pisanosaurus should be removed from the base of the Ornithischia and should no longer be considered the oldest representative of this dinosaurian clade. Expand
Structure and Evolution of the Ankle Bones in Pterosaurs and Other Ornithodirans

A synoptic survey of available tarsal bones of pterosaurs shows that the morphology of these bones remained relatively unchanged from the most basal pter dinosaurs to the pteranodontids and the azhdarchoids, although some ornithodiran subgroups evolved unique schemes of development and sequential ossification.

The origin and early radiation of dinosaurs
Abstract Dinosaurs were remarkably successful during the Mesozoic and one subgroup, birds, remain an important component of modern ecosystems. Although the extinction of non-avian dinosaurs at theExpand
On the tracks of the earliest dinosaurs: implications for the hypothesis of dinosaurian monophyly
This study finds no convincing evidence of dinosaur tracks before the late Ladinian and envisages the origin of dinosaurs as a series of three cladogenetic events over an interval of at least 10 million years and possibly as much as 25 million years, which is as well-supported by fossil evidence as is the currently favoured view of dinosaurian monophyly. Expand
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. Expand
The first 50 Myr of dinosaur evolution: macroevolutionary pattern and morphological disparity
Different aspects of the dinosaur radiation (diversity, disparity and abundance) were decoupled, and the overall macroevolutionary pattern of the first 50 Myr of dinosaur evolution is more complex than often considered. Expand

The recognition of what are now commonly termed the Dinosauria, as a peculiar group of the Reptilia, is due to that remarkable man whose recent death all who are interested in the progress of soundExpand
On the origin of high growth rates in archosaurs and their ancient relatives: Complementary histological studies on Triassic archosauriforms and the problem of a “phylogenetic signal” in bone histology
The new data suggest that the possibility of reaching and maintaining very high growth rates through ontogeny could have been a basal characteristic of archosauriforms, and ornithosuchians apparently retained and even enhanced the high growth rate of many basal archosuriforms during most of their ontogenetic trajectories.

The Early Evolution of Archosaurs: Relationships and the Origin of Major Clades
A time-calibrated phylogeny of Archosauriformes indicates that the origin and initial diversification of archosauria occurred during the Early Triassic following the Permian-Triassic extinction. Expand
Phylogeny and classification of thecodontian reptiles
An understanding of thecodontian tarsi is necessary if the authors are to understand the evolution of the later archosaurs, and this work attempts to trace some of the the codontian lineages on the basis of tarsal anatomy. Expand
Faunal replacement in the Triassic of South America
Improvements in the locomotor apparatus are discernible in seven groups of archosaurs and indicate that a great adaptive radiation took place before the oldest recorded fauna dominated by archosaurs appeared. Expand

ABSTRACT Many hypotheses have been proposed for the rise of dinosaurs, but their early diversification remains poorly understood. This paper examines the occurrences, species diversity and abundanceExpand
