Iguanadon were dinosaurs native to Earth. The Museum of the Last Ones sold masks in the shape of Iguanadon heads in its gift shop. Frank wore one of these masks when selling Mervin the Missing Link to Professor Dougal Dunnock. (PROSE: The Last Dodo)
Iguanodon were presumably one the specimens that the Silurians bought back from extinction when they took over Earth in an alternate timeline. (PROSE: Blood Heat)
