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

主要差异

  • Both were lambeosaurine hadrosaurs with hollow cranial crests used as resonating chambers for low-frequency vocalizations.
  • Parasaurolophus had a long, swept-back tubular crest extending up to 1.8 m; Corythosaurus had a rounded, helmet-shaped crest.
  • Parasaurolophus (9.5 m, ~2,500 kg) was slightly larger than Corythosaurus (9 m, ~3,800 kg).
  • Both lived in Late Cretaceous North America and are among the most recognizable hadrosaurs.
  • Corythosaurus is named for its helmet-like crest resembling a Corinthian war helmet; Parasaurolophus means 'near crested lizard'.
