Diplodocus was one of the longest dinosaurs ever! It had a very long neck and an even longer tail. From head to tail, it was longer than two school buses lined up. Diplodocus walked on four big legs and was a gentle plant eater.
Diplodocus could swing its long tail like a whip to scare away enemies. It ate leaves from tall trees by stretching its long neck way up high. Even though Diplodocus was super long, its head was very small. A baby Diplodocus was tiny compared to its giant parents!
