Description
Hypsilophodon (/ ˌhɪpsɪˈlɒfoʊdɒn/; meaning "high-crested tooth") is a neornithischian dinosaur genus from the Early Cretaceous period of England. It has traditionally been considered an early member of the group Ornithopoda , but recent research has put this into question.
The first remains of Hypsilophodon were found in 1849; the type species , Hypsilophodon foxii, was named in 1869. Abundant fossil discoveries were made on the Isle of Wight , giving a good impression of the build of the species. It was a small, agile bipedal animal with an herbivorous or possibly omnivorous diet, measuring 1.5–2 m (4.9–6.6 ft) long and weighing 20 kg (44 lb). It had a pointed head equipped with a sharp beak used to bite off plant material, much like modern day parrots.
Older studies have given rise to a number of misconceptions about Hypsilophodon that it was an armored, arboreal animal and that it could be found in areas outside of Wight. During the past decades, new researches have gradually shown this to be incorrect.
