Living: The Hypsilophodon ate of the small plants that grew between the rivers and swamps, which covered a large area of the southern England’s shores. These well-known dinosaurs used their beak to take the leaves of the plants and the tongue to push it into the spacey cheeks.

Just like today’s cows the Hypsilophodon chewed its food by moving its lower jaw from side to side, and the worn out teeth were replaced with new ones. Because of the found in 1849, where 24 Hypsilophodons were found together, they must have been in herds, which gave them a better defense-system. But these dinosaurs could do nothing but run if they were attacked by the Theropods. Then again, the Hypsilophodons were some of the fastest dinosaurs of all. Even in top speed they could change direction with its long stiff tail which helped it to keep balance.

Skeleton: A greater investigation of this skeleton shows that the Hypsilophodon was a runner with a very advanced jaw construction and a shinbone longer than the thigh.

Legs: The legs worked almost as a crank, which held the body nearly in balance. And once, a scientist called the Hypsilophodon legs for pendulums because of their ability to swing back and forward very fast.

Tail: The long pointed tail helped the body in balance, and has never touched the ground except when the dinosaur rested.
