主な相違点
- 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.
ご存知でしたか？
Brachiosaurus weighed roughly 4x more than Diplodocus.
Both Brachiosaurus and Diplodocus were herbivores.
Both dinosaurs lived during the Jurassic Late period and may have coexisted.
Diplodocus was discovered 25 years earlier, in 1878.
Both belong to the Sauropoda clade, making them relatively close relatives.
