The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.
Libby received the Nobel Prize in Chemistry for his work in 1960.
The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.

I have integrated this web page on human evolution into an electronic text, " Nature's Holism - Holism.In 1898, Marie Curie discovered the phenomenon of radioactivity, in which unstable atoms lose energy, or decay, by emitting radiation in the form of particles or electromagnetic waves.By 1904 physicist Ernest Rutherford showed how this decay process could act as a clock for dating old rocks.The Triceratops brow horn was excavated in May 2012 and stored at the Glendive Dinosaur and Fossil Museum.The Museum, which has since 2005 been in cooperation with the Paleochronology Group, a team of consultants in geology, paleontology, chemistry, engineering, and education, sent a sample of the outer portion of the Triceratops brow horn to Head of the Paleochronology Group Hugh Miller, at his request, in order to carry out Carbon-14 dating.Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.
