New ankylosaur (Thyreophora, ornithischia) remains from the Upper Cretaceous of Patagonia
Journal of South American Earth Sciences, 2019 Abstract Fossil evidences of the presence of ankylosaurian dinosaurs in Gondwana are scarce but consistent, being found in Antarctica, Oceania and South America. In spite that there are no nominated species in South America, the ankylosaur fossil record has increased in the last years.

A Nodosaurid Ankylosaur (Dinosauria: Ornithischia) from the Lower Cretaceous of Texas
Journal of Vertebrate Paleontology, 1995ABSTRACT A partial nodosaurid ankylosaur skeleton from Lower Cretaceous littoral deposits of Texas represents a new genus and species, Texasetes pleurohalio. It is distinguished by a prong-like scapular spine that is directed toward the innermost point of the glenoid, development of a small prespinous fossa, and retention of a splint-like fourth ...

, 2011 Morphology and function of ankylosaur dinosaur limbs are explored and analyzed using comparative morphology and finite element analysis. Reconstruction of the forelimb and posture of Pinacosaurus grangeri matches well with trackways attributed to ankylosaurs.

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 ...

A New Nodosaurid Ankylosaur from the Chaochuan Formation of Dongyang, Zhejiang Province, China
Acta Geologica Sinica - English Edition, 2013Abstract:Dongyangopelta yangyanensis gen. et sp. nov. from the Chaochuan Formation (Albian – Cenomanian) of Dongyang, Zhejiang Province, China is characterized: the convex anterior surface of the first presacral rod centrum strongly inflates laterally and slightly curves posteriorly; the fused pelvic shield composes of larger pebble‐shaped bosses ...

External and internal structure of ankylosaur (Dinosauria; Ornithischia) osteoderms
2010Here I assess the use of osteoderms in systematics with comparative material from fossil and extant tetrapod taxa. Putative differences among three groups (ankylosaurid, nodosaurid, and polacanthid) were evaluated. Archosaur osteoderms have cortices surrounding a cancellous core.

A juvenile ankylosaur referable to the genusEuoplocephalus(Reptilia, Ornithischia)
Journal of Vertebrate Paleontology, 1986ABSTRACT A specimen of a juvenile ankylosaur from the Upper Cretaceous Horseshoe Canyon Formation (Red Deer River, Alberta, Canada) includes a nearly complete pes, the first reported for the genus Euoplocephalus. Differences between juvenile and adult ankylosaurs are qualitatively similar to differences reported for juvenile and adult stegosaurs.
