Ankylosaur diversity

There were three types of ankylosaurs – the nodosaurids, ankylosaurids and polacanthids. They differed slightly in a number of features including shape of the skull, structure of the tail, and amount and structure of body spines and armour.

Examples of ankylosaurs include:

  • Sauropelta edwardsorum – nodosaurid, USA, 115–112 million years ago
  • Euoplocephalus tutus – ankylosaurid, North America, 76–68 million years ago
  • Gargoyleosaurus parkpini – polacanthid, North America, 156–146 million years ago
