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 ...

Abstract: A new ankylosaurid species of Crichtonsaurus, C. benxiensis sp. nov., is erected based on a well preserved skeleton and a nearly complete skull found in the Sunjiawan Formation (Cenomanian‐Turonian), Beipiao, Liaoning Province. Crichtonsaurus benxiensis sp. nov. is characterized by width 84.6% of length of the skull, a deep depression located

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 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 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 ...

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 ...

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 A partial skull of a new ankylosaurid dinosaur, Nodocephalosaurus kirtlandensis gen. et sp. nov., differs from known ankylosaurids in possessing a distinctive post-maxillary/lacrimal (osteoderm) ridge and a prominent quadratojugal protuberance that projects anteroventrally.
