Abstract
Excavations at Liang Bua, a large limestone cave on the island of Flores in eastern Indonesia, have yielded evidence for a population of tiny hominins, sufficiently distinct anatomically to be assigned to a new species, Homo floresiensis1. The finds comprise the cranial and some post-cranial remains of one individual, as well as a premolar from another individual in older deposits. Here we describe their context, implications and the remaining archaeological uncertainties. Dating by radiocarbon (14C), luminescence, uranium-series and electron spin resonance (ESR) methods indicates that H. floresiensis existed from before 38,000 years ago (kyr) until at least 18 kyr. Associated deposits contain stone artefacts and animal remains, including Komodo dragon and an endemic, dwarfed species of Stegodon. H. floresiensis originated from an early dispersal of Homo erectus (including specimens referred to as Homo ergaster and Homo georgicus)1 that reached Flores, and then survived on this island refuge until relatively recently. It overlapped significantly in time with Homo sapiens in the region2,3, but we do not know if or how the two species interacted.

Abrantes assisted with IRSL and TL analyses, J. Olley made the high-resolution gamma spectrometry measurements, D. Huntley and O. Lian provided advice on anomalous fading, and R. Bailey suggested the isothermal measurement of red TL. Wasisto, M. Roach and K. Morwood assisted with the stratigraphic sections, plans and stone artefact drawings, and P. Brown and P. Jordan commented on earlier drafts of this paper.Author contributions M.J.M., R.P.S. and R.G.R. planned and now co-ordinate the research program funded by the ARC Discovery Project grant, which includes the Liang Bua project.
