WebMost of the specimens were found to have minimal intratooth variation in carbon isotopes (< 2.3‰), suggesting isotopically uniform diets through time and revealing no obvious periods of physiological change. However, one of the two sampled hominin teeth displayed a temporal carbon isotope shift (3.2‰) that was significantly greater than ... WebCarbon has 15 known isotopes with various half-lives. The longest half-life is carbon-14. Carbon-14 is commonly used for radiometric dating. This technique allows for the approximation of the age of a sample based on the amount of carbon-14 present. The other natural isotopes of carbon are carbon-12 and carbon-13. henke supermanWebThe differences are small - one carbon pool may have 98.8% 12 C while another may have 99.2% 12 C - but modern machines, called isotope ratio mass spectrometers, can detect these differences quite easily. Pools with relatively more 13 C (less 12 C) are called “heavy” and those with less 13 C are called “light”. henke tuinmachines
