Anatomy, biomechanics, and evolution of the archosaur ribcage with implications for the evolution of ventilation
DownloadFall 2023
Extant birds and crocodylians are modern representatives of Archosauria, a group of amniote vertebrates with a long evolutionary history that may be traced back to the Triassic Period. On the paths to extant bird and crocodylians, early archosaurs diversified and occupied many niches available...

Inferred musculature and kinematics of the forelimb in a lambeosaurine hadrosaurid dinosaur
DownloadSpring 2022
Hadrosaurid dinosaurs are largely considered to be facultatively bipedal. However, a distinct lack of well-described hadrosaurid postcranial material in the literature makes comparative analysis of hadrosaurid biomechanics difficult. A newly recovered lambeosaurine (crested) hadrosaurid from the...

Ceratopsidae is a group of non-avian dinosaurs known for their distinctive cranial ornamentation and horns. This ornamentation has become the focal point of ceratopsid research and therefore has led to a state of affairs in ceratopsid palaeontology in which taxa are diagnosed on the basis of...

The Paleobiology, Paleoecology, and Evolution of Thescelosauridae (Ornithischia) from Alberta, Canada
DownloadFall 2021
Thescelosauridae is a basal neornithischian dinosaur clade that flourished in the Cretaceous from the Aptian to the Maastrichtian. This diverse but poorly studied group of small-bodied herbivores is divided taxonomically into Orodrominae and Thescelosaurinae, and existed in Asia and North and...
