Sauropod dinosaurs get a lot of attention for their long necks, and for good reason– they’re the longest-necked animals ever discovered. Some sauropods’ necks stretched fifty feet– six times the length of a giraffe’s. But their necks aren’t their only outstanding feature. Diplodocus is one of the longest dinosaurs ever discovered, and a lot of that length is in their slender, whip-like tail. This tail could reach lengths of up to forty-five feet.

Why did Diplodocus have such a long tail? Scientists aren’t sure. It might have been used to thrash out at predators, or maybe even to make a loud sound like a cracking whip. Paleontologists are still working to discover more!
