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.
