Bizarre dermal armour suggests the first African ankylosaur
Nature Ecology & Evolution, 2021Ankylosauria 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).

A juvenile ankylosaur from China
Naturwissenschaften, 2001Juvenile ankylosaur specimens are very rare. A new ankylosaur, Liaoningosaurus paradoxus gen. et sp. nov., is described based on a beautifully preserved juvenile ankylosaur specimen from the famous Yixian Formation of Liaoning, China. Liaoningosaurus has a large bony plate (somewhat shell-like) shielding the abdomen. This discovery represents the first

Pathological pitting in ankylosaur (Dinosauria) osteoderms
International Journal of Paleopathology, 2016Large ulcerative pits on the external surface of ankylosaur (Dinosauria) osteoderms have been recognized for many years. They have been ascribed without supporting evidence to damage by predator teeth or to disease. The discovery of numerous examples of pitted osteoderms in a monospecific ankylosaur (Gastonia n.sp.) bone bed in eastern Utah (USA ...

Skull of a Jurassic ankylosaur (Dinosauria)
Nature, 1998The 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 well-preserved specimens from the Upper Cretaceous period of Asia and North America.

Gut contents of a small ankylosaur
Journal of Vertebrate Paleontology, 2000The diet of fossil vertebrates is usually inferred from the forms of the teeth, sometimes assisted by an analysis of the jaw mechanics. Although generally useful for distinguishing carnivores from herbivoresexcept for a few cases where the teeth reliably reflect a specific food, such as for fish-eating pterosaurs-this method doesn't identify either the

A review of pelvic shield morphology in ankylosaurs (Dinosauria: Ornithischia)
Journal of Paleontology, 2011The pelvic shield of ankylosaurian dinosaurs refers to an area of osteoderms lacking differentiated transverse bands over the pelvic region and it is used as a diagnostic character for various ankylosaur groups. The pelvic shield character varies across ankylosaur taxa but is typically coded as a binary character or is excluded from phylogenetic ...
