Hypsilophodon was a small, fast-running, plant-eating dinosaur.
It lived 125 million years ago, was 2.3 metres long (7/8 feet), including tail, and weighed about the same as a man.

It was originally thought to be a young Iguanodon which could climb trees.
Later it was realised to be a different species, and to be a running dinosaur, not adapted for climbing.
