Homo floresiensis : the Hobbit Homo floresiensis is a species of dwarf human discovered at the Liang Bua cave on the Indonesian island of Flores in 2003 (Brown et al. 2004, Morwood et al. 2004, Lahr and Foley 2004). H. floresienses was only about 1 meter in height and fully bipedal, with a very small brain size of 417cc. The skull has human-like teeth with a receding forehead and no chin. floresiensis fossils have been discovered from 38,000 to 18,000 years ago, though archeological evidence suggests it lived at Liang Bua between at least 95,000 and 13,000 years ago. It used stone tools and fire, and hunted pygmy elephants (mostly juvenile ones), Komodo dragons, and the giant rats found on Flores. Its discoverers believe that floresiensis is a dwarf form of Homo erectus - it is not uncommon for dwarf forms of large mammals to evolve on islands. The most complete floresiensis fossil, LB1, consists of an almost complete skull and a partial skeleton consisting of leg bones, parts of the pelvis, hands and feet, and some other fragments. LB1 was an adult of about 30, probably female judging by the pelvis. Males could have been larger, though the other fossils found so far indicate only individuals about the same size as LB1. Because of the damp condition and young age, the bones of LB1 have not fossilized (i.e. had not turned to stone), and reportedly had the consistency of mashed
