Systematics and phylogeny of Stegosauria (Dinosauria: Ornithischia)
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

Phylogeny of the ankylosaurian dinosaurs (Ornithischia: Thyreophora)
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

A new long-necked ‘sauropod-mimic’ stegosaur and the evolution of the plated dinosaurs
Stegosaurian dinosaurs have a quadrupedal stance, short forelimbs, short necks, and are generally considered to be low browsers. A new stegosaur, Miragaia longicollum gen. et sp. nov., from the LateExpand

The locomotor musculature of basal ornithischian dinosaurs
ABSTRACT The earliest ornithischian dinosaurs were small bipeds that possessed the derived, retroverted pubis that is synapomorphic for the clade. Their forelimbs were modified for grasping.Expand

Osteological Correlates for Quadrupedality in Ornithischian Dinosaurs
The evolution of quadrupedality from bipedal ancestors is an exceptionally rare transition in tetrapod evolution, but it has occurred several times within the herbivorous dinosaur clade Ornithischia.Expand

Downsizing a giant: re-evaluating Dreadnoughtus body mass
Estimates of body mass often represent the founding assumption on which biomechanical and macroevolutionary hypotheses are based. Recently, a scaling equation was applied to a newly discoveredExpand

Fibres and cellular structures preserved in 75-million–year-old dinosaur specimens
Exceptionally preserved organic remains are known throughout the vertebrate fossil record, and recently, evidence has emerged that such soft tissue might contain original components. We examinedExpand

RE-DESCRIPTION OF THE POSTCRANIAL SKELETON OF THE MIDDLE JURASSIC STEGOSAUR HUAYANGOSAURUS TAIBAII
Abstract Previous descriptions of the postcranial skeleton of the primitive stegosaur Huayangosaurus taibaii (Middle Jurassic: People's Republic of China) are insufficient for characterExpand

The Postcranial Skeleton of an Exceptionally Complete Individual of the Plated Dinosaur Stegosaurus stenops (Dinosauria: Thyreophora) from the Upper Jurassic Morrison Formation of Wyoming, U.S.A.
Although Stegosaurus is one of the most iconic dinosaurs, well-preserved fossils are rare and as a consequence there is still much that remains unknown about the taxon. A new, exceptionally completeExpand

Limb-Bone Scaling Indicates Diverse Stance and Gait in Quadrupedal Ornithischian Dinosaurs
Background The most primitive ornithischian dinosaurs were small bipeds, but quadrupedality evolved three times independently in the clade. The transition to quadrupedality from bipedal ancestors isExpand
