Disease in the Cretaceous: a comparative study of Iguanodon and hadrosaur palaeopathology
… and Dryosaurus, to Iguanodon and Late Cretaceous hadrosaurids, the latter showing the highest frequency of palaeopathologies. Statistical analysis of selected museum collections demonstrates a relationship between injuries and body regions possibly indicating similar aetiologies for different …

An Effective Polychromatic X-ray Beam for Quantitative Analysis of Fossil Compositions
… Specifically, those of a tyrannosaur and a hadrosaur from the Frenchman and Wapiti Formations, respectively, are studied and compared to others from these formations. The bulk of the analysis is done using Synchrotron X-ray Fluorescence data collected at the Canadian Light Source in …

Reconstructing the ecological relationships of the latest Cretaceous Antarctic dinosaurs and how functional tooth morphology influenced diet and ecological niche among basal Ornithopod dinosaurs
… elasmarians, a parankylosaurian ankylosaur, a hadrosaur and a suspected megaraptor, all are represented by fragmentary remains have emerged from the same horizon of the Sandwich Bluff Member (SBM) of the López de Bertodano Formation and were thus, all contemporaneous with one another. This …

Taphonomic comparison of Hypacrosaurus stebingeri (Hadrosauridae: Lambeosaurinae) bonebeds from the upper Campanian Oldman and Two Medicine formations of Alberta and Montana
Hadrosaurid social structure is still poorly understood. Evidence from bonebeds suggests that juvenile individuals lived apart from herds composed of older individuals, a phenomenon called age segregation. However, the timing at which juvenile individuals became segregated and later rejoined a …

Osteohistology and Growth of Edmontosaurus and Assessment of Life History Changes in Hadrosaurid Dinosaurs
… life history aspects in extinct organisms. Hadrosaurid dinosaurs, the dominant large-bodied terrestrial herbivores in most Late Cretaceous ecosystems, have an exceptional fossil record consisting of over 60 species and multiple ontogenetic bonebeds making them an ideal clade on which to …
