A new genus and species of dinosauriform is described from the Triassic of south‐west England. The description is based on isolated elements recovered from an assemblage of other dissociated tetrapod remains that include crocodylomorphs, rauisuchiforms and sphenodontians. The key elements in the new taxon are the ilium, astragalus, and the humerus, and these exhibit five synapomorphies of Dinosauria. Three of these, namely a largely to fully perforate acetabulum, the presence of a brevis fossa…

Abstract An accumulation of skeletons of the pre-dinosaur Silesaurus opolensis, gen. et sp. nov. is described from the Keuper (Late Triassic) claystone of Krasiejów in southern Poland. The strata are
Basal dinosauriform and theropod dinosaurs from the mid–late Norian (Late Triassic) of Poland: implications for Triassic dinosaur evolution and distribution
The rise of dinosaurs during the Triassic is a widely studied evolutionary radiation, but there are still many unanswered questions about early dinosaur evolution and biogeography that are hampered
A new specimen of Guaibasaurus candelariensis (basal Saurischia) from the Late Triassic Caturrita Formation of southern Brazil
The comparison of the anatomy of a second incomplete skeleton of Guaibasaurus candelariensis to that of basal Saurischia suggests that the origin of the “Prosauropoda” was from unknown basal
A new early dinosaur (Saurischia: Sauropodomorpha) from the Late Triassic of Argentina: a reassessment of dinosaur origin and phylogeny
TLDR
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.
New dinosaur species from the Upper Triassic Upper Maleri and Lower Dharmaram formations of Central India
ABSTRACT The beginning of dinosaur evolution is currently known based on a handful of highly informative Gondwanan outcrops of Ischigualastian age (late Carnian–early Norian). The richest Triassic
The phylogeny of Tetanurae (Dinosauria: Theropoda)
TLDR
An exhaustive examination of all basal tetanurans and all existing character data, taking advantage of recent discoveries and adding new morphological, temporal and geographic data achieved significantly improved phylogenetic resolution.
A new dinosaur with theropod affinities from the Late Triassic Santa Maria Formation, south Brazil
TLDR
Nhandumirim waldsangae shows that some typical theropod characters were already present early in dinosaur evolution, and it represents possibly the oldest record of the group known in Brazil.
Non-dinosaurian Dinosauromorpha
Abstract Ichnological evidence suggests that dinosauromorphs originated by the Early Triassic, and skeletal remains of non-dinosaur representatives of the clade occur from the Anisian to the end of
The Late Triassic dinosauromorph Sacisaurus agudoensis (Caturrita Formation; Rio Grande do Sul, Brazil): anatomy and affinities
Abstract Silesauridae is an exclusively Triassic group of dinosauromorphs, knowledge on the diversity of which has increased dramatically in the last few years. Silesaurid relationships are still

Dinosaur Monophyly and a New Class of Vertebrates
TLDR
Evidence is presented that dinosaurs are a single, monophyletic group, and that the key advancements of endothermy and high exercise metabolism are justification for removing dinosaurs from the Reptilia and placing them with birds in a new class, the Dinosauria.
Dinosaurian precursors from the Middle Triassic of Argentina: Lagerpeton chanarensis
TLDR
There is no evidence that Lagerpeton and other small-bodied dinosauromorphs in the Los Chanares fauna, namely “Lagosuchus” lilloensis, comprise a monophyletic group.
Primitive dinosaur skeleton from Argentina and the early evolution of Dinosauria
TLDR
The discovery of Eoraptor supports the hypothesis that dinosaurs diverged rapidly at small body size from a common ancestor, with the principal herbivorous and carnivorous lineages present by the middle Carnian.
The Complete Skull and Skeleton of an Early Dinosaur
TLDR
Fossils of Herrerasaurus and younger dinosaurs from Upper Triassic beds in Argentina suggest that the dinosaurian radiation was well under way before dinosaurs dominated terrestrial vertebrate communities in taxonomic diversity and abundance.
Scleromochlus taylori and the origin of dinosaurs and pterosaurs
TLDR
A reanalysis of crown–group archosaur relationships confirms the split into Crurotarsi (crocodile relatives) and Ornithodira (bird relatives), as well as the clear division of Ornithadira into Pterosauria and Dinosauromorpha.
Phylogeny of the Crocodylotarsi, with reference to archosaurian and crurotarsan monophyly
TLDR
The phylogeny of the Crocodylotarsi was re-examined based on study of most relevant fossil material of the early non–crocodyliform members of the clade.
The skull and neck of the basal theropod Herrerasaurus ischigualastensis
TLDR
The skull of Herrerasaurus ischigualastensis has a rectangular profile and a transversely narrow snout and other features of the skull constitute dinosaurian synapomorphies, such as the loss of the postfrontal and small post-temporal opening.
THE MESOZOIC FISSURES OF THE BRISTOL CHANNEL AREA AND THEIR VERTEBRATE FAUNAS
TLDR
From this reconstruction emerges an important feature which characterizes the whole Bristol Channel fauna, namely, that the members of this fauna lived on the higher ground of the continent of the period, the only known example of a mesozoic fauna of this type.
Phylogenetic definitions and nomenclature of the major taxonomic categories of the carnivorous Dinosauria (Theropoda)
TLDR
The new node-based name Eumaniraptora is proposed to refer to the most recent common ancestor of Deinonychus and Neornithes and all descendants of that ancestor.
