The article presents information on determining the features of a new species of primitive human discovered called hobbits. The ancient anatomical features of the skeleton shared many similarities with 1.8-million-year-old human remains found at Dmanisi in the Republic of Georgia. So researchers anticipated it to be at least hundreds of thousands of years old. But because the skeletal remains were the only known examples of an entirely new species, we could not afford to destroy any of it by using direct dating methods that consumed any bones or teeth. Parts of the skeleton were still articulated, indicating "Hobbit" had died …

Statistical Aspects Of Equivalent Dose And Error Calculation And Display In Osl Dating: An Overview And Some Recommendations, R Galbraith, Richard Roberts

All Quaternary dating methods involve the measurement of one or more variables to estimate the age of a sample. Each measured quantity has an associated error and uncertainty, and may also be subject to natural variation. We review the statistical estimation of such uncertainties and variation for comparing and interpreting age estimates, with specific reference to the estimation of equivalent dose (De) values in the optically stimulated luminescence (OSL) dating of sediments. We discuss statistical aspects of OSL signal and background estimation, the determination of De values for multi-grain aliquots and individual mineral grains from the same and different samples, …
