The higher-level phylogeny of Archosauria (Tetrapoda: Diapsida)

This analysis produces a well-resolved phylogeny, which recovers mostly traditional relationships within Avemetatarsalia, places Phytosauria as a basal crurotarsan clade, finds a close relationship between Aetosaurian and Crocodylomorpha, and recovers a monophyletic Rauisuchia comprised of two major subclades.

Superiority, Competition, and Opportunism in the Evolutionary Radiation of Dinosaurs

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 osteology of Neovenator salerii (Dinosauria: Theropoda) from the Wealden Group (Barremian) of the Isle of Wight

Allosauroids were a widespread theropod superfamily, but the best-known representatives are Allosaurus itself (Gilmore, 1920; Madsen, 1976) from North America and Sinraptor (Currie and Zhao, 1993)…

The evolution of Metriorhynchoidea (mesoeucrocodylia, thalattosuchia): an integrated approach using geometric morphometrics, analysis of disparity, and biomechanics

This study illustrates the importance of using a varied toolkit of techniques that together with phylogeny, quantitative assessment of diversity, form, and function help elucidate the macroevolutionary pattern of fossil clades.

A new clade of archaic large-bodied predatory dinosaurs (Theropoda: Allosauroidea) that survived to the latest Mesozoic

It is demonstrated that the problematic allosauroids Aerosteon, Australovenator, Fukuiraptor and Neovenator form a previously unrecognised but ecologically diverse and globally distributed clade (Neovenatoridae, new clade) with the hitherto enigmatic theropods Chilantaisaurus, Megaraptora and the Maastrichtian Orkoraptor.

Basal Abelisaurid and Carcharodontosaurid Theropods from the Lower Cretaceous Elrhaz Formation of Niger

We report the discovery of basal abelisaurid and carcharodontosaurid theropods from the mid Cretaceous (Aptian—Albian, ca. 112 Ma) Elrhaz Formation of the Niger Republic. The abelisaurid, Kryptops…

Tyrannosaur Paleobiology: New Research on Ancient Exemplar Organisms

The biology and evolutionary history of tyrannosaurs are reviewed and their phylogenetic relations are updated to include several new fossils, showing that tyrannosaurs originated by the Middle Jurassic but remained mostly small and ecologically marginal until the latest Cretaceous.

Phylogeny of Allosauroidea (Dinosauria: Theropoda): Comparative analysis and resolution

A core subset of allosauroids is analysed using cladistic methodology and several comparative methods and the recovered most parsimonious topology shows a strong overall match with the stratigraphical record and is much more congruent with stratigraphy than any alternative topology.
