ABSTRACT The Quantou Formation of Jilin Province, People's Republic of China, has recently yielded an important new fauna of ‘middle’ Cretaceous vertebrates. This fauna includes the small-bodied cerapodan ornithischian dinosaur Changchunsaurus parvus, represented by excellent cranial and postcranial material. When initially described, Changchunsaurus was hypothesed to represent one of the most basal known ornithopods; however, similarities to ceratopsians were also noted, suggesting that… 
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
TLDR
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 Yinlong downsi (Ornithischia: Ceratopsia) from the Upper Jurassic Shishugou Formation of Xinjiang, China
ABSTRACT Yinlong downsi, from the Upper Jurassic Shishugou Formation, Xinjiang, northwestern China, is the oldest known ceratopsian dinosaur. Here we provide a detailed description of the skull and
A new basal ornithopod dinosaur from the Lower Cretaceous of China
TLDR
It is tentatively hypothesized that both Changmiania liaoningensis specimens were suddenly entrapped in a collapsed underground burrow while they were resting, which would explain their perfect lifelike postures and the complete absence of weathering and scavenging traces.
A New Basal Ornithopod (Dinosauria, Ornithischia) from the Late Cretaceous of Mongolia
TLDR
The most complete prepared specimen of Haya exhibits a sizeable gastrolith mass, representing only the second occurrence among ornithopods, and provides weak support for grouping Haya with the Chinese Cretaceous taxa Jeholosaurus and Changchunsaurus, suggesting a greater hidden diversity of such animals in Asia.
A new basal ornithopod (Dinosauria: Ornithischia) from the Early Cretaceous of Texas
TLDR
Material from a minimum of twenty-nine individuals of a new ornithopod, represented by nearly every skeletal element, was recovered from the Proctor Lake locality in the Twin Mountains Formation of north-central Texas, providing insight into the growth patterns of this species.
A New Taxon of Basal Ceratopsian from China and the Early Evolution of Ceratopsia
TLDR
A new comprehensive phylogeny of ceratopsians weakly supports both Yinlong and Hualianceratops as chaoyangsaurids (along with Chaoyangsaurus and Xuanhuaceratops), as well as the monophyly of Chaoyangosauridae + Psittacosaurus, suggesting a basal split between these clades before the Late Jurassic.
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
Basal ornithopod (Dinosauria: Ornithischia) teeth from the Prince Creek Formation (early Maastrichtian) of Alaska
A diverse and prolific record of polar dinosaurs comes from the Upper Cretaceous (Campanian–Maastrichtian) sediments of the Prince Creek Formation exposed on Alaska’s North Slope. Previous assignment
A new basal ornithopod dinosaur (Frenchman Formation, Saskatchewan, Canada), and implications for late Maastrichtian ornithischian diversity in North America
TLDR
Identification of a third species of Thescelosaurus from the late Maastrichtian of North America suggests that this taxon was more diverse than previously recognized, and shows an increase in diversity from the Campanian through theLate MaastRichtian, contrasting the trends seen in most other ornithischian clades.
A new hadrosauriform dinosaur from the Wessex Formation, Wealden Group (Early Cretaceous), of the Isle of Wight, southern England
A new genus and species of non-hadrosaurid hadrosauriform dinosaur, Brighstoneus simmondsi gen. et sp. nov., is described from the Lower Cretaceous Wessex Formation of the Isle of Wight. The new

A PRIMITIVE ORNITHOPOD FROM THE EARLY CRETACEOUS QUANTOU FORMATION OF CENTRAL JILIN, CHINA
TLDR
Changchunsaurus has a long predentary, which suggests it might have an immobile mandibular symphysis as in ceratopsians, and it is similar to derived ornithopods in the morphology of the predentary with bilobate ventral process end.
Cranial anatomy of a new crocodyliform (Archosauria: Crocodylomorpha) from the Lower Cretaceous of Song-Liao Plain, northeastern China
Rugosuchus nonganensis, a new genus and species of crocodyliform, is erected on the basis of its peculiar cranial features. This late Early Cretaceous species represents the second, and most
A basal ceratopsian with transitional features from the Late Jurassic of northwestern China
TLDR
Character distributions along the marginocephalian lineage reveal that, compared to the bipedal Pachycephalosauria, the dominantly quadrupedal ceratopsians lost many marginocesphalian features and evolved their own characters early in their evolution.

Although the group played an important role in the evolution of Late Mesozoic terrestrial ecosystems, the early evolutionary history of the ornithischian dinosaurs remains poorly understood. Here, we
Yamaceratops Dorngobiensis, a New Primitive Ceratopsian (Dinosauria: Ornithischia) from the Cretaceous of Mongolia
TLDR
Yamaceratops shares two synapomorphies (tubercles on the ventral edge of the angular and shape of the jugal) with Liaocer atops, indicating that the transient presence of derived characters may be prevalent in the early evolutionary history of Ceratopsia.

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