{# ═══════════════════════════════════════════════════════════════════════════ Key differences (from DinoComparison model) ═══════════════════════════════════════════════════════════════════════════ #}

主要差异

  • 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.
