The Dwarf Rhabdodon (Zalmoxes) is a dinosaur under the family Rhabdodontidae that lived in the Maastrichtian age of the Cretaceous period. It makes an appearance in the dinosaur documentary Dinosaur Planet
On Hateg Island, Dwarf Rhabdodon are seen being hunted by a pack of Dwarf Dromaeosaurs, with the pack successfully killing a slower individual. A herd of the rhabdodonts later appear, where two males battle for dominance over the herd. In the ensuing fight, the challenger is badly injured by the defending male's thumb spike and is knocked to the ground. A group of Allodaposuchus move in and kill the wounded animal, before Pod arrives and scares away the crocodiles from the kill.
Though the creature's design greatly resembles Rhabdodon, and the Dinoviewer from the Discovery website refers to them as Rhabdodon at one point, in the episode, both the mainland and dwarf variants are erroneously referred to as Iguanodon.
There's already a real world ornithopod dinosaur on the Hateg Islands and it was called Zalmoxes. But the creature wasn't known about during the time the show was being made.
