There is no year 0; 1BC is followed by 1 AD.", beginning with Aurignacian deposits containing saucerlike living hollows with central hearths.

The Aurignacian levels are followed by Perigordian and Proto-Magdalenian and probably Proto-Solutrean levels.

Two things in the method have to be allowed for: first, the 'date' given is never exact.

The /- figure, which should always be quoted, is a statistical one, meaning that there is a 2 to 1 chance that the correct date lies within that bracket.

The method drastically reduces the quantity of datable material required.. Libby showed the essential uniformity of carbon-14 in living material and went on to measure the radiocarbon level in organic samples dated historically -- materials as old as 5,000 years from sources such as Egyptian tombs.

Radiocarbon dates show similar conditions prevailed in North America at about the same time. CATEGORY: site DEFINITION: One of the most important painted Palaeolithic caves (as is Lascaux, France) and one of the earliest discovered (1879).

The site is in the Cantabrian Mountains of northeast Spain and the 280-meter long cave is famous for its polychrome animals, which include deer, bison, and wild boar painted in red, black, and a range of earth colors.

The proportions of radioactive and inert carbon are identical throughout the vegetable and animal kingdoms' carbon cycle.

When organic matter dies it ceases to exchange its carbon, as carbon dioxide, with the atmosphere, so its C14 dwindles by decay and is not replenished.

Most of the art in the cave was produced by Solutrean and Magdalenian peoples, with one layer radiocarbon-dated to c 13,000 .
