The first Diplodocus fossil was discovered in 1877 in the US and was described by the American paleontology professor Othniel Charles Marsh.
Diplodocus was a very long animal, up to 25 meter long and could weigh up to 12 tones. Diplodocus had a long neck, a short but heavy body, and a very long tail which it kept in the air at all times. This tail was used as a whip in order to protect itself against predators.
This vertebra is one of the smaller tail vertebra.
