主な相違点
- Both were small feathered theropods, but Oviraptor (1.6 m) is a Cretaceous oviraptorosaur while Archaeopteryx (0.5 m) is a Jurassic bird-line dinosaur.
- Oviraptor brooded its eggs like a modern bird; Archaeopteryx shows transitional features between dinosaurs and birds.
- Oviraptor had a toothless beak and cranial crest; Archaeopteryx had teeth and no crest.
- Archaeopteryx could likely fly; Oviraptor had arm feathers suggesting display but was primarily terrestrial.
- Oviraptor was misnamed as an egg thief — later fossils revealed it was a devoted nest-brooder.
