Example Sentences
Recent Examples on the Web Researchers say radiocarbon dates of chemicals in the mammoth bones, from a mother and her calf, indicate the animals lived about 37,000 years ago in what’s now New Mexico. 
Tom Metcalfe, NBC News, 4 Aug. 2022 As a result, the radiocarbon made its way into the plants, the animals, and eventually humans. Joshua Hawkins, BGR, 27 June 2022 Further, cells that formed within that period would have had higher amounts of radiocarbon in the DNA. Joshua Hawkins, BGR, 27 June 2022 In 2018, Jarman published a study of the inconsistent radiocarbon dates among the old bones in the garden. Joshua Levine, Smithsonian Magazine, 30 Mar. 2022 This means the radiocarbon levels have been declining for years. Joshua Hawkins, BGR, 27 June 2022 An international team of archaeologists explored Cueva de Ardales from 2011 to 2018, then used radiocarbon and uranium-thorium dating techniques to understand the cave’s history. Sarah Kuta, Smithsonian Magazine, 3 June 2022 This arrowhead, made of reindeer antler and probably also used to hunt reindeer, radiocarbon-dates to 2,000-3,000 years ago. Kiona N. Smith, Ars Technica, 26 Apr. 2022 Jarman argued that the discrepancy could be explained by the different diets of the people whose bones were radiocarbon-dated.
