主要差异
- Apatosaurus (22 m, ~22,700 kg) was shorter but significantly heavier than Diplodocus (25 m, ~14,000 kg).
- Both lived in the Late Jurassic Morrison Formation and were likely contemporaries.
- Apatosaurus had a more robust, barrel-like body; Diplodocus had a more slender, elongated build.
- Apatosaurus was formerly (and incorrectly) synonymized with Brontosaurus — Brontosaurus is now considered a separate valid genus.
- Both had long, whip-like tails that may have been used for defense or acoustic signaling.
