主な相違点

  • Ankylosaurus (10 m, ~6,000 kg) was larger than Sauropelta (5.2 m, ~1,500 kg).
  • Ankylosaurus had a bone-crushing tail club; Sauropelta was a nodosaurid without a tail club, relying on armor and shoulder spikes instead.
  • Sauropelta lived in the Early Cretaceous; Ankylosaurus lived in the Late Cretaceous.
  • Sauropelta had prominent cone-shaped shoulder spines for lateral defense; Ankylosaurus had flatter, more integrated osteoderms.
  • Both were quadrupedal herbivores with extensive bony armor, but they represent two different ankylosaur families (ankylosauria vs nodosauridae).
