Ankylosauria is a diverse clade of armoured dinosaurs whose members were important constituents of many Cretaceous faunas. Phylogenetic analyses imply that the clade diverged from its sister taxon, Stegosauria, during the late Early Jurassic, but the fossil records of both clades are sparse until the Late Jurassic (~150 million years ago). Moreover, Ankylosauria is almost entirely restricted to former Laurasian continents, with only a single valid Gondwanan taxon. Spicomellus afer gen. et sp…

A new early-branching armoured dinosaur from the Lower Jurassic of southwestern China

An early-diverging thyreophoran from the Lower Jurassic Fengjiahe Formation of Yunnan Province, China is described on the basis of an associated partial skeleton that includes skull, axial, limb and armour elements and can be diagnosed as a new taxon based on numerous cranial and postcranial autapomorphies.

A new early branching armored dinosaur from the Lower Jurassic of southwestern China

This new taxon, Yuxisaurus kopchicki, represents the first valid thyreophoran dinosaur to be described from the Early Jurassic of Asia and confirms the rapid geographic spread and diversification of the clade after its first appearance in the Hettangian.

A new Cretaceous thyreophoran from Patagonia supports a South American lineage of armoured dinosaurs

The discovery of a new armoured dinosaur from the early Late Cretaceous of Argentina, recovered phylogenetically using various datasets either as a basal thyreophoran or a stem ankylosaur, closely related to Scelidosaurus is reported.

New Ankylosaurian Cranial Remains From the Lower Cretaceous (Upper Albian) Toolebuc Formation of Queensland, Australia

Australian dinosaur research has undergone a renaissance in the last 10 years, with growing knowledge of mid-Cretaceous assemblages revealing an endemic high-paleolatitude Gondwanan fauna. One of its

Skull of a Jurassic ankylosaur (Dinosauria)

The origin and early evolution of many major dinosaur groups are poorly known because specimens are rare. One of these groups, the Ankylosauria, or armour-plated dinosaurs, is best known from

Phylogeny of the ankylosaurian dinosaurs (Ornithischia: Thyreophora)

Dedicated methods for coding continuous characters could be used in future to improve the resolution of ankylosaur phylogeny, particularly in order to explore the relationships within the poorly resolved nodosaurid clade.

First evidence of ankylosaurian dinosaurs (Ornithischia: Thyreophora) from the mid-Cretaceous (late Albian–Cenomanian) Winton Formation of Queensland, Australia

LEAHEY, L.G. & SALISBURY, S.W., 2013. First evidence of ankylosaurian dinosaurs (Ornithischia: Thyreophora) from the mid-Cretaceous (late Albian–Cenomanian) Winton Formation of Queensland, Australia.

Systematics, phylogeny and palaeobiogeography of the ankylosaurid dinosaurs

A revised phylogenetic analysis resulted in a monophyletic Ankylosauridae consisting of Ahshislepelta, Aletopelta, Gastonia, Gobisaurus, Liaoningosaurus, Shamosaurus and a suite of derived ankylosaurusids (Ankylosurinae).

A new primitive Neornithischian dinosaur from the Jurassic of Patagonia with gut contents

Despite showing a general stegosaurian appearance, the extensive phylogenetic analysis carried out depicts Isaberrysaura mollensis gen. et sp.

Stegosauria: a historical review of the body fossil record and phylogenetic relationships

A new phylogeny, which includes all valid stegosaurian taxa, largely agrees with previous studies and shows the European Dacentrurinae was sister taxon to Stegosaurus.

Scelidosaurus harrisonii (Dinosauria: Ornithischia) from the Early Jurassic of Dorset, England: biology and phylogenetic relationships

A critical assessment of datasets used to analyse the systematics of ornithischians has led to a revised dataset that positions Scelidosaurus as a stem ankylosaur, rather than a stem thyreophoran, and the value of phylogenetic definitions is reconsidered in the light of the new thyreophile cladogram.

A Late Cretaceous polar dinosaur fauna from New Zealand

Abstract New fossils of dinosaurs and pterosaurs have been found in the conglomeratic facies of the Maungataniwha Member of the Tahora Formation (Campanian) of New Zealand. These derive from a large


Abstract:  Remains of a peculiar traversodontid cynodont, Protuberum cabralensis gen. et sp. nov., are described herein. The material was collected from two outcrops representing the Therapsid
