During their long evolutionary history, neornithischian dinosaurs diverged into several clades with distinctive adaptations. However, the early evolution within Neornithischia and the resolution of the phylogenetic relationships of taxa situated near the base of the clade remain problematic. This is especially true for those taxa traditionally placed at the base of Ornithopoda, either as ‘hypsilophodontids’ or at the base of the diverse clade Iguanodontia. Recent studies are improving our… 

New information on ornithopod dinosaurs from the Late Jurassic of Portugal

Ornithopods are one of the most speciose group of herbivorous dinosaurs, rising during the Jurassic and getting extinct at the Cretaceous–Paleogene boundary. However, most of the attention has been

New small-bodied ornithopods (Dinosauria, Neornithischia) from the Early Cretaceous Wonthaggi Formation (Strzelecki Group) of the Australian-Antarctic rift system, with revision of Qantassaurus intrepidus Rich and Vickers-Rich, 1999

Abstract. The Flat Rocks locality in theWonthaggi Formation (Strzelecki Group) of the Gippsland Basin, southeastern Australia, hosts fossils of a late Barremian vertebrate fauna that inhabited the

Ornithopod Jaws from the Lower Cretaceous Eumeralla Formation, Victoria, Australia, and Their Implications for Polar Neornithischian Dinosaur Diversity

ABSTRACT Ornithopod dinosaurs are relatively common in the Cretaceous of Australia, particularly in the state of Victoria, which has yielded five taxa to date: two from the upper Strzelecki Group

A new Heterodontosaurus specimen elucidates the unique ventilatory macroevolution of ornithischian dinosaurs

A new, fully articulated skeleton of the early branching ornithischian Heterodontosaurus tucki is presented, revealing a suite of novel postcranial features unknown in any other ornithischerian, with implications for the early evolution of the group.

Assessing conflict between early neornithischian tree topologies

This study assesses three recent independent neornithischian phylogenetic studies that have recovered topologies congruent with one of these placements, and provides several suggestions for future analyses with the aim of resolving areas of conflict within the neornitischian tree.

Fostoria dhimbangunmal, gen. et sp. nov., a new iguanodontian (Dinosauria, Ornithopoda) from the mid-Cretaceous of Lightning Ridge, New South Wales, Australia

ABSTRACT Globally, non-hadrosauroid iguanodontians (‘basal iguanodontians’) reached their acme in terms of diversity during the Early Cretaceous. However, Gondwanan representatives of this clade are

The phylogenetic nomenclature of ornithischian dinosaurs

The nomenclature of ornithischian dinosaur clades is revised; 76 preexisting ornithischerian clade names are revisited, their recent and historical use is reviewed, and their phylogenetic definitions are formally established.



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.

Osteology and phylogeny of Zalmoxes (n. g.), an unusual Euornithopod dinosaur from the latest Cretaceous of Romania

A phylogenetic analysis of basal euornithopods indicates that the non‐hadrosaurid material from Hateg comprises two distinct, but congeneric, species, and indicates the recognition of a ghost lineage, extending from the most recent common ancestor of Rhabdodontidae and Iguanodontia, which extends for 73 million years.

The postcranial osteology and phylogenetic position of the small ornithischian dinosaur Changchunsaurus parvus from the Quantou Formation (Cretaceous: Aptian–Cenomanian) of Jilin Province, north‐eastern China

A phylogenetic analysis finds relationships amongst basal ornithopods to be extremely poorly resolved, but supports a sister-group relationship between Changchunsaurus and Jeholosaurus shangyuanensis and suggests that an endemic clade of small-bodied bipedal ornithipods existed in north-east China during the Early to ‘middle’ Cretaceous.

Cranial Anatomy of Wendiceratops pinhornensis gen. et sp. nov., a Centrosaurine Ceratopsid (Dinosauria: Ornithischia) from the Oldman Formation (Campanian), Alberta, Canada, and the Evolution of Ceratopsid Nasal Ornamentation

A new taxon of a highly adorned basal centrosaurine, Wendiceratops pinhornensis gen. et sp.

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.

Phylogeny of Basal Iguanodonts (Dinosauria: Ornithischia): An Update

The results provide some new information on the phylogeny of basal iguanodonts, pertaining especially to obscure or recently described taxa, and support some recent taxonomic revisions, such as the splitting of traditional “Camptosaurus” and “Iguanodon”.

A Middle Jurassic heterodontosaurid dinosaur from Patagonia and the evolution of heterodontosaurids

A new ornithischian dinosaur from the Middle Jurassic Cañadón Asfalto Formation in central Patagonia, Argentina is reported, and derived features of its anatomy indicate that Manidens belongs to Heterodontosauridae, as the sister taxon of HeterODontosaurus and other South African heterodontsaurids.

The ornithopod dinosaur Rhabdodon from the Late Cretaceous of France : anatomy, systematics and paleobiology

The phylogenetic analysis confirms that Rhabdodon can be placed in a distinct family,Rhabdodontidae, which also includes its sister taxon, Zalmoxes, from which it is distinguished by numerous postcranial characters.

Postcranial anatomy of Lesothosaurus diagnosticus (Dinosauria: Ornithischia) from the Lower Jurassic of southern Africa: implications for basal ornithischian taxonomy and systematics

This study has found that the material of L. diagnosticus and S. dangershoeki almost certainly represents the same taxon and that the apparent differences between these genera is probably a product of ontogentic (rather than taxonomic) differences.

Phylogeny, Histology and Inferred Body Size Evolution in a New Rhabdodontid Dinosaur from the Late Cretaceous of Hungary

Rhabdodontid remains from the Santonian of western Hungary provide evidence for a new, small-bodied form, which is assigned to Mochlodon vorosi n.
