What is Ankylosaurinae?
Ankylosaurinae is a subfamily of prehistoric animals used in this catalogue to connect related field notes. Ankylosaurus, Pinacosaurus and Saichania share this grouping, and their fossils come from the Cretaceous period, with finds reported from North America and Asia. The shared grouping is a starting point for comparison rather than proof of identical lifestyles.
How this group is defined here
Members are the 3 field notes whose family or immediate parent group in the Paleobiology Database catalogue is Ankylosaurinae. The interpreted diet field across the group is herbivore, based on skeletal features rather than direct observation. Groups are revised when new fossils are described, and some genera are placed here with less certainty than others, so each field note records its sources and limits.
