Neither the pre-existing Egyptian chronology nor the new radiocarbon dating method could be assumed to be accurate, but a third possibility was that the In the 1960s, Hans Suess was able to use the tree-ring sequence to show that the dates derived from radiocarbon were consistent with the dates assigned by Egyptologists.

This was possible because although annual plants, such as corn, have a The New Zealand curve is representative of the Southern Hemisphere; the Austrian curve is representative of the Northern Hemisphere.

thus introduced takes a long time to percolate through the entire volume of the ocean.

The deepest parts of the ocean mix very slowly with the surface waters, and the mixing is uneven.

To verify the accuracy of the method, several artefacts that were datable by other techniques were tested; the results of the testing were in reasonable agreement with the true ages of the objects.

Over time, however, discrepancies began to appear between the known chronology for the oldest Egyptian dynasties and the radiocarbon dates of Egyptian artefacts.

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.

Animals eat the plants, and ultimately the radiocarbon is distributed throughout the biosphere.
