Updating my blog celebrating the 10th anniversary of the discovery of Homo floresiensis, better known as the ‘Hobbit’, a letter in Nature has revised the most recent dates for the remains from 12,000 years back to 60,000 years. The sediment layers in the cave of Liang Bua on the Indonesian island of Flores, where the remains were discovered, had not been laid evenly, leading to an initial miscalculation.

Stone artefacts attributed to H. floresiensis are dated more recently, to 50,000 years ago.

The biggest implication of the new dates is that it is now less likely that the ‘Hobbit’ coexisted at the same time as H. sapiens on Flores. Although it cannot be ruled out, the earliest dates for human occupation at Flores is 50,000 years, leaving a very narrow window of opportunity.
