The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

Libby of the University of Chicago after the end of World War 2.

Carbon follows this pathway through the food chain on Earth so that all living things are using carbon, building their bodies until they die.

A tiny part of the carbon on the Earth is called Carbon-14 (C14), or radiocarbon.

During the period of a plant's life, the plant is taking in carbon dioxide through photosynthesis, which is how the plant makes energy and grows.

Animals eat plants, and some eat other animals in the food chain.

These prices include sampling (at Oxford), sample preparation, stable carbon isotope and AMS isotope measurement.

We reserve the right to refuse material for dating if the provenance is uncertain or for other ethical considerations.

I have tried here to answer some of the frequently asked questions that I receive from students via email, as well as providing some basic information about scientific dating methods.

"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
