The program depicts the dinosaur called Oviraptor as a ferocious carnivore that kills smaller animals with ease, and even threatens Velociraptor. More modern theories suggest this is highly erroneous. Not only does the documentary mix up Oviraptor with Citipati (since the latter's fossils have been mistaken for those of Oviraptor for decades), scientists now think the animal was actually a herbivore, rather than a predator.
