An exceptionally preserved Lower Cretaceous ecosystem
- Z. Zhou, P. Barrett, Jason Hilton
- Medicine, Geography
- Nature
- 20 February 2003
Fieldwork in the Early Cretaceous Jehol Group, northeastern China has revealed a plethora of extraordinarily well-preserved fossils that are shaping some of the most contentious debates in… Expand
The evolution of sauropod feeding mechanisms
- P. Upchurch, P. Barrett
- Biology
- 1 August 2000
Introduction Sauropods were gigantic, long-necked, herbivorous dinosaurs, which dominated many Jurassic and Cretaceous terrestrial faunas. First appearing in the fossil record during the Early… Expand
A new hypothesis of dinosaur relationships and early dinosaur evolution
- M. Baron, D. B. Norman, P. Barrett
- Biology, Medicine
- Nature
- 23 March 2017
For 130 years, dinosaurs have been divided into two distinct clades—Ornithischia and Saurischia. Here we present a hypothesis for the phylogenetic relationships of the major dinosaurian groups that… Expand
A phylogenetic analysis of basal sauropodomorph relationships: Implications for the origin of sauropod dinosaurs2
- P. Upchurch, P. Barrett, Peter M. Galton
- Biology
- 2007
New discoveries, revision of existing taxa and the application of cladistic analysis have all shed light on the relationships of basal sauropodomorphs. Nevertheless, the interrelationships proposed… Expand

Systematics and phylogeny of Stegosauria (Dinosauria: Ornithischia)
- Susannah C. R. Maidment, D. B. Norman, P. Barrett, P. Upchurch
- Biology
- 1 January 2008
Synopsis Stegosauria is a clade of ornithischian dinosaurs characterised by a bizarre array of dermal armour extending, in two parasagittal rows, from the cervical region to the end of the tail.… Expand
Sauropod dinosaurs from the Lower Cretaceous of eastern Asia: taxonomic and biogeographical implications
- P. Barrett, Y. Hasegawa, M. Manabe, S. Isaji, H. Matsuoka
- Geology
- 1 November 2002
Sauropod dinosaurs are poorly represented in the Lower Cretaceous of eastern Asia. Here, we describe a number of isolated sauropod teeth from the Kuwajima Formation (?Berriasian–?Hauterivian) of… Expand
Phylogeny of the ankylosaurian dinosaurs (Ornithischia: Thyreophora)
- R. S. Thompson, J. Parish, Susannah C. R. Maidment, P. Barrett
- Biology
- 17 May 2012
Ankylosauria is a diverse clade of quadrupedal ornithischian dinosaurs whose remains are known from Middle Jurassic to latest Cretaceous sediments worldwide. Despite a long history of research,… Expand
Inter-Vertebral Flexibility of the Ostrich Neck: Implications for Estimating Sauropod Neck Flexibility
- M. J. Cobley, E. Rayfield, P. Barrett
- Biology, Medicine
- PloS one
- 14 August 2013
The flexibility and posture of the neck in sauropod dinosaurs has long been contentious. Improved constraints on sauropod neck function will have major implications for what we know of their foraging… Expand
THE DIET OF OSTRICH DINOSAURS (THEROPODA: ORNITHOMIMOSAURIA)
- P. Barrett
- Biology
- 1 March 2005
: The diets of ornithomimosaurian dinosaurs (Theropoda: Ornithomimosauria) have proved to be contentious owing to a dearth of unambiguous evidence in support of carnivory, omnivory or herbivory.… Expand
The skull of Yunnanosaurus huangi Young, 1942 (Dinosauria: Prosauropoda) from the Lower Lufeng Formation (Lower Jurassic) of Yunnan, China
- P. Barrett, P. Upchurch, X.-D. Zhou, X. Wang
- Biology
- 1 June 2007
The Lower Lufeng Formation (Lower Jurassic: ?Hettangian-?Sinemurian) of Yunnan Province, China, has yielded an important and diverse fauna of terrestrial vertebrates that is dominated by early… Expand
