主な相違点
- Sinosauropteryx was the first non-avian dinosaur found with fossilized proto-feathers (filamentous structures, not flight feathers); Archaeopteryx had fully developed flight feathers.
- Sinosauropteryx (1 m, ~0.6 kg) was smaller than Archaeopteryx (0.5 m, ~0.5 kg) in body mass terms though similar in length.
- Sinosauropteryx lived in Early Cretaceous China; Archaeopteryx in Late Jurassic Germany.
- Sinosauropteryx's reddish-brown and white striped tail pattern is reconstructed from fossilized melanosomes — one of the first dinosaurs with known coloration.
- Archaeopteryx could likely fly or glide; Sinosauropteryx was a fast, ground-running insectivore with no flight capability.
