主な相違点
- Psittacosaurus (2 m, ~20 kg) and Protoceratops (1.8 m, ~83 kg) were both small Asian ceratopsians, but Protoceratops was heavier.
- Psittacosaurus is a basal ceratopsian without a prominent frill; Protoceratops had a well-developed frill though no true horns.
- Psittacosaurus had quill-like structures on its tail and showed countershading camouflage based on fossil melanosomes.
- Psittacosaurus lived in the Early Cretaceous; Protoceratops lived in the Late Cretaceous — separated by tens of millions of years.
- Psittacosaurus is one of the most species-rich dinosaur genera (10+ species); Protoceratops has two recognized species.
