Investigating the diversity and palaeobiogeography of ankylosaurian dinosaurs using tooth morphometrics

The presence of a basal cingulum, fluting, and overall size have been used to differentiate nodosaurid and ankylosaurid teeth for decades. However, the taxonomic utility of tooth morphology in ankylosaurs has not yet been quantitatively tested ...
