Oviraptorosaurs have evolved toothless beaks, had feathers, and their diet was highly debated (although some could be omnivores, a specimen of Oviraptor was found with a lizard in it's gullet, indicating a partial carnivorous lifestyle).
Oviraptorosaurs are also known from their eggs and nests.

The third episode of Prehistoric Park featured Incisivosaurus, a primitive species of oviraptorosaur. It was depicted as a flightless but feathered dinosaur that used its feathers to court females of its species and chase away rival males. It is also depicted as a vegetarian.
There are rumors that Protarchaeopteryx and Incisivosaurus are one and the same. But currently, no proof has been found.
