Voir la ficheThe Maastrichtian, Transylvanian giant azhdarchid pterosaur Hatzegopteryx sp. preys on the rhabdodontid iguanodontian Zalmoxes. Because large predatory theropods are unknown on Late Cretaceous Haţeg Island, giant azhdarchids may have played a key role as terrestrial predators in this community.
Ferenceratops was initially classified under the ornithopod genus Zalmoxes, until it was found that it more closely resembled an early ceratopsian. Ferenceratops was a small quadrupedal herbivore, growing to 1.5-2 m in body length, likely using the characteristic ceratopsian beak to process vegetation.
