Using tree rings, the calibration of carbon-14 has been extended back to ~4,760 B. Of course, they could all be wrong, but if enough independent studies agree with each other, then being wrong becomes a more remote possibility.In addition to tree rings, scientists have looked at what are called lake varves in Northern Sweden.

So while many date to dance, you might say scientists do the "three-step" to date.Bristlecone pine is both worse and better to use than oak.It is worse, in that the rings are very thin, and roughly 5% of the time the tree either does not grow a ring in a year or else grows two rings.When you have records dated by the scribes, as well as actual mummies and the carbon-14 dates are not off by hundreds of years but by thousands, you either have to throw away every historical record, or else there was a general failure with carbon-14 dating. Solar intensity, the earth's magnetism, and CO To "face up" to the absolute age problem, scientists devised calibration scales based on tree rings, lake varves, and ice cores.Oak trees can live for 200-300 years, and they grow a new tree ring every year.When a plant or animal dies, it stops taking in carbon.
