Abstract Dianchungosaurus lufengensis was erected on the basis of fragmentary isolated jaw elements (a left premaxilla and left and right partial lower jaws) from the Lower Lufeng Formation (Lower Jurassic) of Yunnan Province, China. Yang referred Dianchungosaurus to the Heterodontosauridae (Ornithischia, Ornithopoda), as several features appeared to indicate affinity with the southern African genus Heterodontosaurus. However, reexamination of the type material demonstrates that the holotype… 

A reassessment of the purported ankylosaurian dinosaur Bienosaurus lufengensis from the Lower Lufeng Formation of Yunnan, People’s Republic of China

The earliest definitive ornithischian dinosaurs are from the Early Jurassic and are rare components of early dinosaur faunas. The Lower Lufeng Formation (Hettangian–Sinemurian) of Yunnan Province,

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.

Notes on the postcranial anatomy of the heterodontosaurid dinosaur Heterodontosaurus tucki, a basal ornithischian from the Lower Jurassic of South Africa

A description is provided of the best-represented adult postcranial skeleton of the Heterodontosauridae Kuhn, 1966 (rather than Romer, 1966), that of Heterodontosaurus tucki Crompton & Charig, 1962

New ornithischian dinosaur material from the Lower Jurassic Lufeng Formation of China

Published records of ornithischian dinosaurs from the Lower Jurassic Lufeng Formation are extremely rare. Here we describe a new ornithischian specimen, FMNH CUP 2338, consisting of an articulated

Anatomy and Cranial Functional Morphology of the Small-Bodied Dinosaur Fruitadens haagarorum from the Upper Jurassic of the USA

The lack of wear facets and plesiomorphic dentition suggest that Fruitadens used orthal jaw movements and employed simple puncture-crushing to process food, suggesting that fruitadens was an ecological generalist, consuming select plant material and possibly insects or other invertebrates.

Taxonomy, morphology, masticatory function and phylogeny of heterodontosaurid dinosaurs

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.

Evaluating hypotheses for the early diversification of dinosaurs

ABSTRACT Many hypotheses have been proposed for the rise of dinosaurs, but their early diversification remains poorly understood. This paper examines the occurrences, species diversity and abundance

Mass extinctions drove increased global faunal cosmopolitanism on the supercontinent Pangaea

It is found that mass extinctions did increase faunal cosmopolitanism across Pangaea during the late Palaeozoic and early Mesozoic, and shared patterns in both biotic crises suggest thatmass extinctions have predictable influences on animal distribution and may shed light on biodiversity loss in extant ecosystems.

A new heterodontosaurid dinosaur (Reptilia: Ornithischia) from the Upper Triassic Red Beds of Lesotho

Dental peculiarities indicate that tooth replacement processes were suppressed in heterodontosaurids; replacement of the teeth seems to have been restricted to a brief period each year (presumably when heterodonsaurids underwent aestivation or hibernation).

Diet of prosauropod dinosaurs from the late Triassic and early Jurassic

All prosauropods were high browsers that extended the feeding range with a long neck and tripodal feeding and used herding and the enormous claw on the pollex for defense, and probably had a muscular gastric mill with stones that was used for grinding the food.
