ABSTRACT The holotype of Dyoplosaurus acutosquameus Parks, 1924 (=Euoplocephalus tutus Lambe, 1910), represents one of the most complete ankylosaurid specimens collected to date. It consists of a partial skull roof, four mandible fragments with two teeth in situ, portions of postcranial armor (some in situ), skin impressions, articulated post-thoracic vertebrae, ten partial thoracic ribs, a partial left ilium, both ischia, and tail club, and associated right radius, left metacarpal IV, femur… 

The ankylosaurid dinosaurs of the Upper Cretaceous Baruungoyot and Nemegt formations of Mongolia

The discovery of a new ankylosaurid skull with some unusual features from the Baruungoyot Formation of Mongolia prompted a systematic review of ankylosaurid specimens from the Baruungoyot and Nemegt

A New Basal Ankylosaurid (Dinosauria: Ornithischia) from the Lower Cretaceous Jiufotang Formation of Liaoning Province, China

Chuanqilong chaoyangensis represents the fourth ankylosaurid species reported from the Cretaceous of Liaoning, China, suggesting a relatively high diversity in Cret Jurassic Liaoning.

Euoplocephalus tutus and the Diversity of Ankylosaurid Dinosaurs in the Late Cretaceous of Alberta, Canada, and Montana, USA

A comprehensive review of material attributed to Euoplocephalus finds support for the resurrection of its purported synonyms Anodontosaurus lambei and Scolosaurus cutleri, and the previously resurrected Dyoplosaurus acutosquameus.

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 ankylosaurid skeleton from the Upper Cretaceous Baruungoyot Formation of Mongolia: its implications for ankylosaurid postcranial evolution

A new articulated postcranial specimen of an indeterminate ankylosaurid dinosaur from the Upper Cretaceous (middle-upper Campanian) Baruungoyot Formation from Hermiin Tsav, southern Gobi Desert,

Postcrania of juvenile Pinacosaurus grangeri (Ornithischia: Ankylosauria) from the Upper Cretaceous Alagteeg Formation, Alag Teeg, Mongolia: implications for ontogenetic allometry in ankylosaurs

Abstract. The ankylosaurine Pinacosaurus is one of the best known ankylosaur to date in terms of the number and preservational quality of specimens. Juvenile to sub-adult postcrania collected by

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.

A relative abundance of more recently collected and prepared cranial material attributable to Euoplocephalus enables a reappraisal of this taxon (including the type specimen), and permits it to be employed as a morphological representative of the clade.

The first detailed description of the lambeosaurine Lambeosaurus magnicristatus confirms that it is a distinct taxon characterized by its comparatively enormous cranial crest, formed predominantly by the caudodorsal process of the premaxilla, and an acute crest-snout angle.

NEW SPECIMENS OF THE RARE ANKYLOSAURID DINOSAUR NODOCEPHALOSAURUS KIRTLANDENSIS (ORNITHISCHIA: ANKYLOSAURIDAE) FROM THE UPPER CRETACEOUS KIRTLAND FORMATION (DE-NA-ZIN MEMBER), SAN JUAN BASIN, NEW MEXICO

The caudal vertebrae are distinct from other known North American ankylosaurids (such as Euoplocephalus tutus), thus reinforcing their taxonomic assignment to N. kirtlandensis.

HISTOLOGY OF ANKYLOSAUR OSTEODERMS: IMPLICATIONS FOR SYSTEMATICS AND FUNCTION

A comparative survey of the histology of postcranial dermal-armor osteoderms of ankylosaurs, including material of polacanthids, ankylosaurids, and nodosaurids is provided to elucidate histological evolution and character polarity.

Ankylosaurian tail clubs of middle Campanian to early Maastrichtian age from western North America, with description of a tiny club from Alberta and discussion of tail orientation and tail club function

Analysis of hindlimb length, tail length, and downward angle of the tail from the hips suggests that the tail was normally carried and swung just above the ground, and was used primarily defensively, for striking at the metatarsals of an attacking theropod.

It is concluded that the most parsimonious interpretation of relationships leads to the separation of the two species of Albertosaurus into Gorgosaurus libratus from the Campanian Dinosaur Park Formation and Albertosaurus sarcophagus from the upper Campanian/lower Maastrichtian Horseshoe Canyon Formation.
