Image:Hypsilophodon Melb Museum email.jpg The first remains of Hypsilophodon were recovered in the early days of paleontology in 1849, when workers on the Isle of Wight dug up the so-called Mantell-Bowerbank block. One piece of it was sold to Gideon Mantell, the other to naturalist James Scott Bowerbank. However, at the time, the bones were thought to belong to a young Iguanodon: first Mantell in 1849,[1] and then Richard Owen in 1855 describing the block as such.[2] Modern research of Hypsilophodon began with the studies of Peter Malcolm Galton, starting with his thesis of 1967.
