Real World EquivalentEdit
Ankylosaurus was a species of Predentate Dinosaur of the late Cretaceous Period. The Fighting Fantasy Ankylosaurus is obviously based on this, but there are problems. The the feet, carapace, skull, and especially the fanged mouth (for what is a herbivore) are wrong for the individual illustrated in Portal of Evil. A much more accurate picture of an Ankylosaurus can be found in Robot Commando.
