主要差异
- Allosaurus and Stegosaurus were contemporaries in the Late Jurassic Morrison Formation, forming a classic predator-prey pair.
- Allosaurus (9.7 m, carnivore) weighed ~2,300 kg; Stegosaurus (9 m, herbivore) weighed ~5,000 kg.
- Stegosaurus defended itself with a spiked tail (thagomizer); evidence of Allosaurus bite marks on Stegosaurus bones confirms they interacted.
- Allosaurus was bipedal and fast; Stegosaurus was slow and quadrupedal with a tiny walnut-sized brain.
- Stegosaurus's back plates may have aided in thermoregulation or display, not direct defense against Allosaurus.
