Intraspecific Variation in the Armoured Dinosaurs (Dinosauria: Ankylosauria)
, 2015Here I assess sources of intraspecific morphological variability in the armoured dinosaurs (Dinosauria: Ornithischia: Ankylosauria), approached from the viewpoints of ontogenetic allometry, fossil bone histology, and individual variation. Juvenile specimens of Pinacosaurus grangeri Gilmore, 1933, demonstrate strong positive allometry in features of ...

A cranium and other associated skeletal elements representing a new ankylosaurid dinosaur, Tatankacephalus cooneyorum gen. et sp. nov. possess several diagnostic features that indicate that this new taxon differs from the only other known ankylosaur from the Cloverly Formation, Sauropelta edwardsorum .

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.

Abstract Four juvenile specimens referable to Pinacosaurus grangeri (Ankylosauria: Dinosauria) are described from the Campanian (Upper Cretaceous) locality Bayan Mandahu in northern Inner Mongolia Autonomous Region (People’s Republic of China). All the specimens preserve the skulls as well as, in some cases, mandibles, postcrania, and osteoderm ...

Abstract Abundant and diverse dinosaur footprints have been discovered recently on bedding surfaces of the Lower Cretaceous Patuxent Formation of Maryland and Virginia. Found along with those ichnofossils is a fossil preserved partially as natural casts and partially as natural molds of a baby nodosaurid ankylosaur so small as to justify interpreting ...

Hungarosaurus tormai is a medium-sized nodosaurid ankylosaur that was described on the basis of four partial skeletons from the Santonian (Upper Cretaceous) of Hungary. In this paper, a new fifth skeleton and several isolated remains are described which greatly improve our knowledge of this primitive nodosaurid ankylosaur.

Abstract The skull of the nodosaurid Niobrarasaurus coleii (Mehl) is redescribed as the result of the discovery of additional material, including the partially crushed braincase. The bone surface shows moderate remodeling, but not to the point of sutural obliteration. The snout section suggests a long, narrow skull more similar to Pawpawsaurus than the
