Dryosaurus did not feature in the main series of Walking with Dinosaurs, though some speculate that the small Hypsilophodontids seen in cameo roles are either a variant of Dryosaurus or Othnielia (Time of the Titans, the Dinosaurs with the red heads, also seen in the background of the panning shot of the pair of Stegosaurus and the Diplodocus herd, and several were seen as charred bodies after the forest fire) It's possible they could've been other Ornithopods like either Drinker or Laosaurus. However it is most likely to be Dryosaurus due to their shape and also because of their population.
