Ankylosaurus

The Ankylosaurus (also known as Ankylosaur) were a type of dinosaur.

Ankylosaurus were part of a herd of dinosaurs that Ace used to destroy a construction site in Cretaceous Mongolia and free alien slaves. (DWM: Living in the Past)

In 2062 the Ankylosaurus were worth 650 points in the I-Spyder Book of Earth Creatures if it was spotted. (NSA: The Last Dodo)

In an alternative timeline, Ankylosaurus were one of the creatures the Silurians bought back from extinction and were allowed to roam free. (NA: Blood Heat)
