S Of twelve elements analyzed in a series of bovid teeth from the Olduvai Gorge, uranium is the only element which varies appreciably with the ages of the samples. Uranium concentrations increase at first, then decrease with increasing age, and therefore cannot be used by themselves to obtain absolute or even relative ages of the samples. A model accounting for the behaviour of uranium is proposed in which uranium is absorbed in the samples during the decay of organic material and is lost after this decay ceases. If one accounts for uranium losses, the concentrations of uranium and its decay products may be used to accurately date skeletal material from the Olduvai gorge
