Reclassification of ankylosaurs with ambiguous taxonomy using tooth morphometrics

open access: yesZoological Journal of the Linnean Society
Abstract New morphometric methods of analysis of phylliform ornithischian teeth provide the opportunity to study clade associations of ankylosaurs of ambiguous taxonomy that include dental material. With recent extensive sampling of ex situ/in situ dentition of ankylosaurs, we present new dental characters for phylogenetic analyses of

An ankylosaur femur from the mid-Cretaceous of the Peace Region of northeastern British Columbia

open access: yes
Dinosaur skeletal material from the mid Cretaceous of Canada is rare, however, the Cenomanian-aged Dunvegan Formation of northeastern British Columbia and northwestern Alberta is rich with ichnofossils attributed to nodosaurid ankylosaurs.

Notes on Ceratopsians and Ankylosaurs at the Royal Ontario Museum

open access: yes, 2012
As part of my dissertation research and general research program focused on horned dinosaurs, I traveled to the Royal Ontario Museum (ROM, Toronto, Ontario, Canada) in the summer of 2006 for a few days of research. The notes were typed in Microsoft Word, and are presented in unedited format on the following pages.

A “bloat-and-float” taphonomic model best explains the upside-down preservation of ankylosaurs

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 2018
Abstract It is widely held that, within the Cretaceous fluvial and marine deposits of North America, ankylosaur remains are typically preserved upside-down; however, this anecdotal observation has yet to be substantiated. Likewise, none of the various hypotheses that purport to explain the frequent occurrence of overturned ankylosaurs has been tested
