The rise and diversification of the dinosaurs in the Late Triassic, from 230 to 200 million years ago, is a classic example of an evolutionary radiation with supposed competitive replacement. A comparison of evolutionary rates and morphological disparity of basal dinosaurs and their chief “competitors,” the crurotarsan archosaurs, shows that dinosaurs exhibited lower disparity and an indistinguishable rate of character evolution. The radiation of Triassic archosaurs as a whole is characterized…

ReviewModels for the Rise of the Dinosaurs

Dinosaurs arose in the early Triassic in the aftermath of the greatest mass extinction ever and became hugely successful in the Mesozoic. Their initial diversification is a classicexampleofa

The origin and early radiation of dinosaurs

The first 50 Myr of dinosaur evolution: macroevolutionary pattern and morphological disparity

TLDR
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.

Resetting the evolution of marine reptiles at the Triassic-Jurassic boundary

TLDR
The end-Triassic mass extinction had a previously unsuspected profound effect in resetting the evolution of apex marine predators of the Mesozoic.

Macroevolutionary patterns in the evolutionary radiation of archosaurs (Tetrapoda: Diapsida)

TLDR
New data is provided on archosaur lineage origination, diversity and lineage evolution, morphological disparity, rates of morphological character change, and faunal abundance during the Triassic–Early Jurassic.

The role of clade competition in the diversification of North American canids

TLDR
Contrary to current expectation, it is found that competition from phylogenetically distant, but ecologically similar, clades played a more substantial role in canid diversification than climate change and body size evolution.

Dinosaur morphological diversity and the end-Cretaceous extinction.

TLDR
There was no universal biodiversity trend and the intensively studied North American record may reveal primarily local patterns, but at least some dinosaur groups did endure long-term declines in morphological variability before their extinction.

The Jurassic rise of squamates as supported by lepidosaur disparity and evolutionary rates

The squamates (lizards, snakes, and relatives) today comprise more than 10,000 species, and yet their sister group, the Rhynchocephalia, is represented by a single species today, the tuatara. The

Early crocodylomorph increases top tier predator diversity during rise of dinosaurs

TLDR
Carnufex bridges a problematic gap in the early evolution of pseudosuchians by spanning key transitions in bauplan evolution and body mass near the origin of Crocodylomorpha.

TLDR
There is no evidence that either thecodontians or dinosaur demonstrated their superiority over mammal-like reptiles in massive competitive take-overs in the latest Triassic, and explanations of dinosaur success based on the competitive superiority of their thermoregulation or locomotory capability are unnecessary.

Tempo and Mode of Evolutionary Radiation in Iguanian Lizards

TLDR
A comparative analytical framework for examining phylogenetic patterns of diversification and morphological disparity with data from four iguanian-lizard taxa that exhibit substantially different patterns of evolution is presented.

TLDR
The transition between the first dinosaurs and more archaic faunas may have extended for 15 to 20 million years and was probably diachronous at different paleolatitudes.

Ascent of Dinosaurs Linked to an Iridium Anomaly at the Triassic-Jurassic Boundary

TLDR
Analysis of tetrapod footprints and skeletal material from more than 70 localities in eastern North America shows that large theropod dinosaurs appeared less than 10,000 years after the Triassic-Jurassic boundary, marking the establishment of dinosaur-dominated communities that prevailed for the next 135 million years.

Comparison with generic richness reveals that the full range of form was essentially attained by the early part of the Caradocian, long before the time of maximal taxonomic diversity.

TLDR
A new Late Triassic suchian archosaur with unusual, highly specialized features that are convergent with ornithomimid dinosaurs is reported, suggesting that these archosaurs show iterative patterns of morphological evolution.

Patterns of morphologic diversification among the Rostroconchia

TLDR
Various metrics indicate that the pattern is not due to poor sampling of Cambro-Ordovician species and thus merits a biological explanation, and the data do not suggest that morphologic evolution became more constrained among rostroconchs as a whole, but instead suggest a reduced characteristic rate of morphologic change in the clade that happened to survive the end-Ordovan extinction.

TLDR
The fossil evidence strongly suggests that no small dinosaurs ever existed in either Jurassic or Cretaceous, and the most convincing proof of the lack of truly small dinosaur species is their absence in the carefully studied microvertebrate concentrates.
