Ankylosaurus

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

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

In 2062, Ankylosaurus were worth 650 points in the I-Spyder Book of Earth Creatures if it was spotted. The last Ankylosaurus was an exhibit in the Museum of the Last Ones. (PROSE: The Last Dodo)

In an alternative timeline, Ankylosaurus was one of the creatures the Silurians bought back from extinction. They were allowed to roam free and were presumably used as pack animals. (PROSE: Blood Heat)

Ankylosaurus was among the dinosaur species farmed by the Sanctified empire. At least two of the Sanctified's Ankylosaurus livestock came through the Cardiff Space-Time Rift to Cardiff in 2008. The Ankylosaurus were ultimately sent by the Torchwood Three team through a rift storm back to where they came from. (COMIC: Rift War!)

Ankylosaurus were among the species placed aboard the Silurian Ark to repopulate the Earth with after the catastrophe the Silurians incorrectly predicted had passed. In the 24th century, the Ankylosaurus specimens aboard the Ark were sent by the Eleventh Doctor to the planet Siluria. (TV: Dinosaurs on a Spaceship)

Behind the scenes
The postcard Brian Williams sends Amy and Rory has a picture of some of the dinosaurs released in Siluria, but one of them shows an Ankylosaurus from BBC's Walking With Dinosaurs rather than Doctor Who.

Ankylosaurus from Dinosaurs on a Spaceship appear as enemies in the video game Doctor Who: Legacy, including a "Giant Ankylosaurus" variant.
