Phylogeny of basal iguanodonts (Dinosauria: Ornithischia): an update.

open access: yesPLoS ONE, 2012
The precise phylogenetic relationships of many non-hadrosaurid members of Iguanodontia, i.e., basal iguanodonts, have been unclear. Therefore, to investigate the global phylogeny of basal iguanodonts a comprehensive data matrix was assembled, including ...

Tooth replacement in the early-diverging neornithischian Jeholosaurus shangyuanensis and implications for dental evolution and herbivorous adaptation in Ornithischia [PDF]

open access: yesBMC Ecology and Evolution
Background Tooth replacement patterns of early-diverging ornithischians, which are important for understanding the evolution of the highly specialized dental systems in hadrosaurid and ceratopsid dinosaurs, are poorly known.

A new stegosaur (Dinosauria: Ornithischia) from the Middle Jurassic of Gansu Province, China [PDF]

open access: yesScientific Reports
Stegosaurs are a minor but iconic clade of ornithischian dinosaurs, yet due to a poor fossil record, their early evolution is poorly understood. Here, we describe a new stegosaur, Baiyinosaurus baojiensis, gen. et sp. nov.

On Asian ornithopods (Dinosauria: Ornithischia). 4. ProbactrosaurusRozhdestvensky, 1966 [PDF]

open access: hybridZoological Journal of the Linnean Society, 2002
The genus Probactrosaurus was first established for material discovered by a joint Russian/Chinese expedition to the Chinese autonomous region of Neimongol (Inner Mongolia). Fossils were collected at a site named Maorty (= Maortu). Material attributable to ornithopod dinosaurs was considered sufficiently distinct to permit the definition of two species
