Scientists have dated fossils found inSouth African caves to between 236,000 to 335,000 years oldusing several different geochronometers, includingoptically stimulated luminescence, a tool that allows us to calculate the last time cave sediments were exposed to light. Another common method, uranium-...

Using the largest dataset of human fossils from Ice Age Europe to date, an international research team shows how prehistoric hunter-gatherers coped with climate change in the period between 47,000 and 7,000 years ago. Population sizes declined sharply during the coldest period, and in the West...
But sometimes, when the conditions are just right, they're preserved as fossils. Several different physical and chemical processes create fossils, according to the New York State Geological Survey. Freezing, drying and encasement, such as in tar or resin, can create whole-body fossils that ...
