两只恐龙在 Sauropoda 演化支内拥有共同祖先。
主要差异
- Brachiosaurus (26 m, ~56,000 kg) was much heavier than Diplodocus (25 m, ~14,000 kg) despite similar length.
- Brachiosaurus had longer front legs than hind legs, giving it a giraffe-like upward posture for high browsing; Diplodocus held its neck roughly horizontal.
- Diplodocus had a proportionally much longer tail that it may have used as a whip; Brachiosaurus had a shorter, stouter tail.
- Both lived in the Late Jurassic Morrison Formation of North America and were likely contemporaries.
- Brachiosaurus had spatula-shaped teeth; Diplodocus had pencil-shaped peg teeth — both adapted for stripping vegetation.
