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