The initial radiation of the dinosaurs in the Triassic period (about 200 million years ago) has been generally regarded as a result of successful competition with the previously dominant mammal-like reptiles. A detailed review of major terrestrial reptile faunas of the Permo-Triassic, including estimates of relative abundance, gives a different picture of the pattern of faunal replacements. Dinosaurs only appeared as dominant faunal elements in the latest Triassic after the disappearance of… Expand
Triassic environments, climates and reptile evolution
Abstract A consideration of all the available data on Triassic vertebrate faunas, and their stratigraphic location reveals a relatively sudden extinction event among the last of the mammal-likeExpand
The Origin of the Dinosaurs El origen de los dinosaurios
The origin of the dinosaurs has long been debated. There are two aspects, phylogenetic and ecological-evolutionary. Much of the phylogenetic confusion has been resolved by cladistic analysis of basalExpand
The roles of herbivory and omnivory in early dinosaur evolution
Consideration of diversity patterns and relative abundance suggests that the ability to eat plants might have been a major factor promoting sauropodomorph success, but that it was less important in the early evolution of Ornithischia. Expand
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
The beginning of the ‘Age of Dinosaurs’: a brief overview of terrestrial biotic changes during the Triassic

Future work directed toward improved absolute age assessments for major faunal assemblages will be critical for a better understanding of the transition from therapsid-dominated to dinosaur-dominated communities during the early Mesozoic. Expand
The Carnian Pluvial Episode in Italy : History of the research and perspectives
The Carnian Pluvial Episode (CPE) was a perturbation of the Late Triassic climate that had a strong impact on marine and terrestrial ecosystems. The CPE is still a relatively neglected episode ifExpand
Dinosaur diversification linked with the Carnian Pluvial Episode
Palaeontological and dated stratigraphic evidence is synthesized to show that dinosaur diversification followed the Carnian Pluvial Episode 234–232 mya, a time when climates switched from arid to humid and back to arid again. Expand
Did dinosaurs invent flowers? Dinosaur—angiosperm coevolution revisited

  • 2001
It is concluded that there are no strong spatiotemporal correlations in support of the hypothesis that dinosaurs were causative agents in the origin of angiosperms; however, dinosaur–angiosperm interactions in the Late Cretaceous may have resulted in some coevolutionary interactions, although direct evidence of such interactions is scanty at present.

Niche partitioning shaped herbivore macroevolution through the early Mesozoic
This work identifies five main herbivore guilds (ingestion generalists, prehension specialists, durophagous specialists, shearing pulpers, and heavy oral processors), and finds that herbivor clades generally avoided competition by almost exclusively occupying different guilds. Expand
Avoiding Competition: the Ecological History of Late Cenozoic Metatherian Carnivores in South America

Any passive replacement or active displacement between the Hathliacynidae and carnivorous Didelphoidea are supported by the fossil record and a partition of the metatherian carnivorous guild seems to have occurred through to the Neogene. Expand


Ecological succession among late palaeozoic and mesozoic tetrapods
The replacement of mammal-like reptiles by dinosaurs is tentatively explained in terms of palaeoclimatology and thermoregulatory physiology and Ornithischians capable of dealing with tough vegetation evolved to occupy the new niches produced by the radiation of conifers in the Jurassic. Expand
The term chronofauna 1 is proposed to differentiate faunal units in which time is an important factor from those in which it is not, and to gain information concerning both physical and biological aspects of environment adequate to provide a background for study of many phases of adaptive modifications of animals.

Permo-Triassic Extinctions: Relation to Sea-Floor Spreading
An analysis of the Permo-Triassic fauna and paleogeography on a stage-by-stage basis supports previous more general summaries by concluding that the number of families of marine invertebrates wasExpand

It is suggested that a trend towards the reduction of the anterior pterygoid muscle took place in aetosaurids, in parallel with a similar trend in ornithischian dinosaurs. Expand
The Evolution of Endothermy in the Phylogeny of Mammals

It is concluded that many of the characteristics that distinguish mammals from reptiles, including endothermy, viviparity, and even lactation, may be related to the marked decrease in body size that occurred in the evolution of mammals from advanced therapsids. Expand
Reconstructing Triassic vegetation of eastern Australasia: a new approach for the biostratigraphy of Gondwanaland
As is widely recognised, fossil florules are difficult to correlate because they appear to have been more controlled by environmental and ecological factors than uniform changes which reflect theExpand

During the Age of Mammals, South America was an isolated continent until the emergence of the Panamanian land bridge about 3.0 Ma; thereafter an intermingling of the long-separated North and SouthExpand
