Method of dating fossils


Conventional carbon dating estimates the age of an artifact based on its content of carbon-14 (C-14), a naturally occurring, radioactive form of carbon. Comparing the C-14 levels in the object to levels of C-14 expected in the atmosphere for a particular historic period allows scientists to estimate the age of an artifact. Both the conventional and new carbon dating methods can determine the age of objects as far back as 45,000 to 50,000 years, Rowe said.

Fossils vary in size from one micrometer bacteria to dinosaurs and trees, many meters long and weighing many tons. A fossil normally preserves only a portion of the ...
