Ornithischians form a large clade of globally distributed Mesozoic dinosaurs, and represent one of their three major radiations. Throughout their evolutionary history, exceeding 134 million years, ornithischians evolved considerable morphological disparity, expressed especially through the cranial and osteodermal features of their most distinguishable representatives. The nearly two-century-long research history on ornithischians has resulted in the recognition of numerous diverse lineages… 

Taxonomic, palaeobiological and evolutionary implications of a phylogenetic hypothesis for Ornithischia (Archosauria: Dinosauria)

The results find further support for the hypothesis that silesaurs comprise a paraphyletic grouping of taxa on the stem of Ornithischia and that successive silesaur taxa acquire anatomical characters anagenetically in a process that culminates in the assembly of what may be described as a ‘traditional’ ornithischian.

Phylogeny of iguanodontian dinosaurs and the evolution of quadrupedality

Iguanodontians are a large and biogeographically widespread group of dinosaurs, known from every modern continent, with a temporal range from the Late Jurassic through the Late Cretaceous. While the

Abundance of large ornithopod dinosaurs in the El Castellar Formation (Hauterivian-Barremian, Lower Cretaceous) of the Peñagolosa sub-basin (Teruel, Spain)

The El Castellar Formation (upper Hauterivian-lowermost Barremian, Lower Cretaceous) in the southwest of the Maestrat Basin (Spain) has yielded diverse dinosaur remains, mostly fragmentary bones.

A new juvenile Yamaceratops (Dinosauria, Ceratopsia) from the Javkhlant Formation (Upper Cretaceous) of Mongolia

A new articulated skeleton of Yamaceratops dorngobiensis is reported from the Khugenetjavkhlant locality at the Shine Us Khudag of the eastern Gobi Desert, Mongolia, which represents the first substantially complete skeleton and the first juvenile individual of this taxon.

Hadrosauroid eggs and embryos from the Upper Cretaceous (Maastrichtian) of Jiangxi Province, China

Background Dinosaur eggs containing embryos are rare, limiting our understanding of dinosaur development. Recently, a clutch of subspherical dinosaur eggs was discovered while blasting for a

The phylogeny of the ornithischian dinosaurs

Surprisingly, Heterodontosauridae is placed as the most basal group of all well‐known ornithischians, phylogenetically distant from a stem‐defined Ornithopoda, creating a topology that is more congruent with the known Ornithischian stratigraphical record.

A basal ornithopod dinosaur from the Cenomanian of the Czech Republic

A new basal ornithopod is described, Burianosaurus augustai gen. nov, which represents the only occurrence of a Cenomanian non-avian dinosaur in Central Europe north of the Alpine Tethyan areas and is diagnosed by a unique suite of characters.

The systematic relationships and biogeographic history of ornithischian dinosaurs

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.

A new phylogeny of Stegosauria (Dinosauria, Ornithischia)

The phylogeny presented here will form the basis for future work on the palaeobiology of the plated dinosaurs and will affect topologies in unpredictable ways, particularly in areas of the tree where there are large amounts of missing data.

Reconsidering the status and affinities of the ornithischian dinosaur Tatisaurus oehleri Simmons, 1965

Tatisaurus is identified as a basal thyreophoran (armoured ornithischian dinosaur); there is no basis for amalgamating it in synonymy with the genus Scelidosaurus, and the proposed creation of a 'Scelidaurus biochron' for the purposes of biostratigraphic correlation of Lower Jurassic outcrops has no utility whatever.

Ecologically distinct dinosaurian sister group shows early diversification of Ornithodira

The analysis suggests that the dentition and diet of silesaurids, ornithischians and sauropodomorphs evolved independently from a plesiomorphic carnivorous form, and Asilisaurus demonstrates the antiquity of both Ornithodira and the dinosaurian lineage.

Untangling the dinosaur family tree

The morphological dataset underpinning the Ornithoscelida hypothesis is evaluated and the results of the new study differ so radically from all previous cladistic analyses, and decades of pre-cladistic research, that they deserve close scrutiny.

Enigmatic dinosaur precursors bridge the gap to the origin of Pterosauria

It is demonstrated that lagerpetids—a group of cursorial, non-volant dinosaur precursors—are the sister group of pterosaurs, sharing numerous synapomorphies across the entire skeleton, substantially shortening the temporal and morphological gap between the oldest pterosaurus and their closest relatives and simultaneously strengthens the evidence that pter dinosaurs belong to the avian line of archosaurs.

Taxon sample and character coding deeply impact unstable branches in phylogenetic trees of dinosaurs

The analysis nested ornithischians and theropods in a sister-group relationship, instead the traditional saurischian-ornithischia dichotomy, supporting the existence of the clade Ornithoscelida, which demonstrates how a single operational taxonomic unit can produces deep rearrangements on the branches of the phylogenetic tree of dinosaurs.
