TLDR
Echinodon is established as a very small-bodied, late-surviving northern heterodontosaurid similar to the other northern genera Fruitadens and Tianyulong, and long-axis rotation of the lower jaw during occlusion is identified here as the most likely functional mechanism underlying marked tooth wear in mature specimens of Heterodontosaurus.

Alan Jack Charig (1927–1997): an overview of his academic accomplishments and role in the world of fossil reptile research

Abstract Alan Jack Charig was Curator of Fossil Amphibians, Reptiles and Birds at the British Museum (Natural History) from 1961 to 1987. We here review his academic accomplishments and the impact of

A Juvenile Skull of the Primitive Ornithischian Dinosaur Heterodontosaurus Tucki from the 'Stormberg' of Southern Africa

TLDR
A new partial skull of a juvenile Heterodontosaurus tucki from the 'Stormberg' of South Africa is described, providing new information on the cranial anatomy of this taxon as well as insights into cranial ontogeny, sexual dimorphism and tooth replacement in heterodontosaurids.

A Phylogenetic Analysis of the Basal Ornithischia (Reptilia, Dinosauria)

TLDR
A phylogenetic analysis of 19 taxonomic units, including two outgroup taxa, produced four most parsimonious trees and a bootstrap analysis was performed to determine the relative support for the resultant phylogeny.

A comprehensive anatomical and phylogenetic evaluation of Dilophosaurus wetherilli (Dinosauria, Theropoda) with descriptions of new specimens from the Kayenta Formation of northern Arizona

TLDR
Many characters of the axial skeleton of Dilophosaurus wetherilli are derived compared to Late Triassic theropods and may be associated with macropredation and an increase in body size in Theropoda across the Triassic-Jurassic boundary.

Systematics and evolutionary history of proterosuchian archosauriforms

TLDR
The results obtained here suggest that the evolutionary history of the archosauriforms during the Early Triassic can be subdivided into a first phase characterized by the short-lived “disaster-clade” Proterosuchidae and a second phase that witnessed the initial morphological and probably palaeoecological diversification of the group.

The systematic relationships and biogeographic history of ornithischian dinosaurs

TLDR
The resulting strict consensus tree is the most well-resolved, stratigraphically consistent hypothesis of basal ornithischian relationships yet hypothesized and provides a comprehensive framework for testing further hypotheses regarding evolutionary patterns and processes within Ornithischia.

The Early Evolution of Archosaurs: Relationships and the Origin of Major Clades

TLDR
A time-calibrated phylogeny of Archosauriformes indicates that the origin and initial diversification of archosauria occurred during the Early Triassic following the Permian-Triassic extinction.

New heterodontosaurid specimens from the Lower Jurassic of southern Africa and the early ornithischian dinosaur radiation

ABSTRACT Heterodontosaurids are poorly understood early ornithischian dinosaurs with extensive geographic and stratigraphic ranges. The group is best known from the Lower Jurassic upper ‘Stormberg

The dinosauria are peculiarly interesting and instructive on account of the combinations in their skeletons of structures which now only occur separately in those of extant Sauropsida; and also on
