Scientists believe yes! Diplodocus's tail tapered to a thin tip and could have been swung fast enough to break the sound barrier, creating a sonic boom like a bullwhip. This could have been used to scare off predators or communicate with other Diplodocus over long distances.

Diplodocus had a tiny head relative to its body - only about 60 cm long! This was actually efficient: a small, lightweight head at the end of a very long neck was easier to maneuver. It had simple, peg-like teeth only at the front of its mouth, which it used to strip leaves from branches.

Contrary to classic images, Diplodocus probably couldn't raise its neck very high. Studies of its vertebrae suggest it held its neck mostly horizontal, sweeping it from side to side like a living vacuum cleaner to feed on low-growing plants and ferns. It may have fed like a grazing cow rather than a giraffe.
