These records give a precise estimation of how much radioactive carbon there was in the atmosphere in any given year, and could help increase the accuracy of how we estimate the age of fossils.Radiocarbon, or Carbon 14, is what archaeologists and anthropologists use to figure out how old things are. Because carbon is an integral part of every living thing, all organisms, like animals and plants, take in carbon while they are alive.So, when they die, they contain the same amount of Carbon 14 as their environment.Scientists know that Carbon 14 has a half-life of 5,730 years, meaning that in 5,730 years, half of the Carbon 14 in a sample will turn into normal, non-radioactive carbon.
By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.They used pottery and other materials in sites to date 'relatively'.They thought that sites which had the same kinds of pots and tools would be the same age.What would happen if a dinosaur bone were carbon dated?- At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method.
