Charles Lyell eagerly met Darwin for the first time on 29 October and soon introduced him to the up-and-coming anatomist Richard Owen, who had the facilities of the Royal College of Surgeons to work on the fossil bones collected by Darwin. Owen's surprising results included other gigantic extinct ground sloths as well as the "Megatherium", a near complete skeleton of the unknown "Scelidotherium" and a hippopotamus-sized rodent-like skull named "Toxodon" resembling a giant capybara. The armour fragments were actually from "Glyptodon", a huge armadillo-like creature as Darwin had initially thought.</ref> These extinct creatures were related to living species in South America.</ref>
