A new data matrix composed of 96 separate taxa and 600 osteological characters was assembled and analysed to generate a comprehensive higher-level phylogenetic hypothesis of basal Archosauromorphs and shed light on the species-level interrelationships of taxa historically identified as proterosuchian archosauriforms.

The new evidence presented here demonstrates that dinosaurs first appeared in the fossil record as a diverse group, although they were a numerically minor component of faunas in which they occur.

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.
A review of the systematic position of the dinosauriform archosaur Eucoelophysis baldwini sullivan & lucas, 1999 from the upper triassic of New Mexico, USA

A cladistic analysis was carried out, which depicts Eucoelophysis as a non-dinosaurian dinosauriform, indicating their survival into the Norian, being co-eval with early dinosaurs.
The earliest bird-line archosaurs and the assembly of the dinosaur body plan.
It is demonstrated that several anatomical features long thought to characterize Dinosauria and dinosauriforms evolved much earlier, soon after the bird-crocodylian split, and that the earliest avemetatarsalians retained the croc Codylian-like ankle morphology and hindlimb proportions of stem archosaurs and early pseudosuchians.
The Origin and Early Evolution of Sauria: Reassessing the Permian Saurian Fossil Record and the Timing of the Crocodile-Lizard Divergence
A revision suggests a minimum fossil calibration date for the crocodile-lizard split of 254.7 Ma, and early archosauromorph growth strategies appear to be more diverse than previously suggested based on new data on the osteohistology of Aenigmastropheus.

A reappraisal of the Cretaceous non-avian dinosaur faunas from Australia and New Zealand: evidence for their Gondwanan affinities
It has often been assumed that Australasian Cretaceous dinosaur faunas were for the most part endemic, but with some Laurasian affinities. In this regard, some Australasian dinosaurs have been…
An unusual new archosauriform from the Middle–Late Triassic of southern Brazil and the monophyly of Doswelliidae
The phylogenetic analysis indicates that Doswellidae is the closest large monophyletic entity to Archosauria, which achieved a wide palaeolatitudinal distribution during the late Middle and Late Triassic time span.
