Unfortunately, the flowstone samples proved to be beyond the limits of the U-Th dating method.For speleothems with ages beyond this, the recently developed U-Pb in the speleothem chronometer provides a viable alternative.The first “Out of Africa” migrations toward western Europe are recorded by the presence of an increase of well-dated sites with hominin settlements such as Dmanisi (Georgia, 1.85–1.78 Ma) (refs 5 and 6), Orce (Spain, 1.5–1.4 Ma) (refs 7 and 8), La Sima del Elefante (Spain, 1.2–1.1 Ma) (ref.

The authors declare that they have no competing interests.Here, we apply the uranium-lead (U-Pb) methods to two flowstones to date the intervening archaeological levels.The U-Pb data, coupled with paleomagnetic constraints, provide an age range from 1.2 to 1.1 Ma.Forget classified personals, speed dating, or other Florida dating sites or chat rooms, you've found the best!Latest activity in Florida Chat: Democrats do what they're told, Having Lied America into .6 Trillion of Imperialist War .
