A team of archaeologists affiliated with multiple institutions in Spain has used a new dating technique to more accurately estimate time differences between Paleolithic Age hearth fires. In their paper published in the journal Nature, the group describes how their new dating technique works, its accuracy range and what their findings reveal about Neanderthals living in a river valley in what is now Spain, approximately 50,000 years ago.
