The Presence of Ankylosaur Tracks in the Guará Formation (Brazil) and Remarks on the Spatial and Temporal Distribution of Late Jurassic Dinosaurs

ABSTRACT The Guará Formation (Paraná Basin, southern Brazil) is an Upper Jurassic unit that yielded a dinosaur ichnoassemblage composed of theropod, ornithopod, and sauropod tracks. A new set of

Bizarre tail weaponry in a transitional ankylosaur from subantarctic Chile.

A new clade of Gondwanan ankylosaurs is proposed, the Parankylosauria, to include the first ancestor of Stegouros-but not Ankylosaurus-and all descendants of that ancestor.

Bizarre tail weaponry in a transitional ankylosaur from subantarctic Chile

Armoured dinosaurs are well known for forms that evolved specialized tail weapons: paired tail spikes in stegosaurs, and heavy tail clubs in advanced ankylosaurs1. Armoured dinosaurs from southern

British plated dinosaurs (Ornithischia, Stegosauridae)

ABSTRACT All specimens of the Stegosauridae from England are described. The material from the lower and upper Bathonian (Middle Jurassic) of Oxfordshire and Gloucestershire is the earliest record of

A New Specimen of Pinacosaurus grangeri (Dinosauria: Ornithischia) from the Late Cretaceous of Mongolia: Ontogeny and Phylogeny of Ankylosaurs

The occurrence of a juvenile ankylosaur from the Upper Cretaceous locality Ukhaa Tolgod in southern Mongolia is reported, indicating that extensive morphological variability exists in the narial anatomy of P. grangeri.

The skull of the basal stegosaur Huayangosaurus taibaii and a cladistic diagnosis of stegosauria

Huayangosaurus is the sister-taxon to all other stegosaurs, which have lost premaxillary teeth, reduced the size of the antorbital fossa, increased the length of the prepubic process of the pubis, and lost lateral scute rows along the trunk.

A review of the Late Jurassic stegosaurs (Dinosauria, Stegosauria) from the People's Republic of China

This taxonomic revision significantly reduces known stegosaurian diversity worldwide, and shows that the Chinese diversity was similar to that of Europe and North America in the Upper Jurassic.

Systematics and phylogeny of Stegosauria (Dinosauria: Ornithischia)

A cladistic analysis of Stegosauria (the first to be based upon direct observation of all relevant specimens) is presented, which indicates that Tuojiangosaurus, Loricatosaurus and Paranthodon are sister taxa to Stegosaurus.

The First Stegosaur (Dinosauria, Ornithischia) from the Upper Jurassic Shishugou Formation of Xinjiang, China

Abstract: A new stegosaur species, Jiangjunosaurus junggarensis, gen. et sp. nov., is erected based on a specimen collected from the Upper Jurassic upper section of the Shishugou Formation in the

A new long-necked ‘sauropod-mimic’ stegosaur and the evolution of the plated dinosaurs

A well-resolved phylogeny supports a new clade that unites Miragaia and Dacentrurus as the sister group to Stegosaurus; this new topology challenges the common view of DacentRurus as a basal stegosaur.

Species concept in North American stegosaurs

The plated thyreophoran or stegosaurian dinosaur Stegosaurusarmatus was named in 1877 by Marsh for fragmentary remains from the Morrison Formation (Upper Jurassic) of Colorado, USA. Subsequent
