 With assistance (possibly from the young sailor Syms Covington acting as his servant) Darwin collected numerous fossils over several days, amusing others with "the cargoes of apparent rubbish which he frequently brought on board".Much of the second day was taken up with excavating a large skull which Darwin found embedded in soft rock, and seemed to him to be allied to the rhinoceros.On 8 October he returned to the site, and found a jawbone and tooth which he was able to identify using Bory de Saint-Vincent's "Dictionnaire classique".
