Living: The Diplodocus ate of high trees, palms, ferns and anything that grew on the meadows. The scientists say that it ate of the treetops by standing on its hind legs, supporting with its tail.

The pointing teeth could rip off leaves and branches, but they were not good to chew with. It had gizzards in its muscular stomach, which "chewed" the food. These dinosaurs walked in herds, because defending them selves would be easier when they were many together. Previously, the scientists thought that the Diplodocus dragged its tail behind it, but since there were no marks after the tail on the ground, they concluded, that it held its tail in the air.

Skull: Its skull was little and contained a very small brain. Beacause it had a nose, which was placed above its eyes, many believed, that it had a trunk like an elephant.

"Double-branched" Chevron: There are "double-braches" on the chevron. They work like an extension in front and behind, and could protect the tail if it was squeezed down into the ground. The word "double-branched" gave also the Diplodocus its name

Whiptail: There were possibly more than 80 vertebras in the tail and the first 19 of them were hollow to make the tail lighter. Further to the end the vertebras were like a pointed vertebra, causing the tail to look like a whip.

Foot: Its round hind legs rested on the wide, five-toed foot with claws on the three first toes.
