Another post on Phys.Org. In this one it is reported that restudying the age of the fossils of Homo floresiensis produced an age greater than first thought. The story can be found at Indonesian 'Hobbits' may have died out sooner than thought

Basically they revisited the site, where digging has continued since the original find, and determined that an error had been made in the original dating. The new dates show that the Hobbits died out around 50,000 years ago, instead of the previous estimate of from 11,000 to 18,000 years ago. This time is in reasonable agreement with the time at which modern humans arrived in the area. So that may be another species that died out because of the presence of modern humans.
