Another type, the Pteranodon, had one individual brought to 20th century Cardiff by the Cardiff Rift. This Pteranodon was captured by Torchwood Three and kept as a mascot. (TW: Everything Changes)

In an alternate universe, an especially large type of Pterosaur was used by the Silurians as a steed. With a 40 foot wingspan, it could easily carry a Silurian. They were used as war steeds in times of battle and would cling to the side of the airships. (NA: Blood Heat)
