The Hypsilophodon was one of the herbivores that lived during the Lower Cretaceous approximately 100 years ago. They belonged to the family, Hypsilophodontidae, which has other species of ornithopods. The Hypsilophodons were one of the longest-surviving dinosaur families during the Late Jurassic to the Late Cretaceous periods.

When & Where
The first specimen of the Hypsilophodon was found in Cowleaze Chine in 1849 by Reverend William Fox which included a skull and was described as a little different compared to the Iguanodon and 20 years after, the type species Hypsilophodon foxii was given by Thomas Henry Huxley, in honor of William Fox. There are a great number of fossils that were discovered on the Isle of Wight which provided much-needed information on the skeletal figure of the dinosaur.
Size & Weight
Wıth the discoveries made on the Isle of Wight, the Hypsilophodon was described as a small bipedal herbivore that reached up to 2.3m and weighs about 50 kilograms.
Mobility & Diet
Like most ornithopods, the Hypsilophodon was a herbivore. With its beak, the dinosaur was believed to have fed off plant materials during the Cretaceous Period. This type of dinosaur was also able to grasp food items that made it easier for them to eat.
- The Hypsilophodons existed from Lower Cretaceous Epoch to 100.5 million years ago.
- 13 different specimens have been found by paleontologists.
- The most interesting point about an Hypsilophodon is that they did not lose their premaxillary teeth as they grow, unlike most dinosaurs and that they also had four toes in each of their hind feet while other bipedal dinosaurs only had three.
