A more difficult to deal problem with radiocarbon dating came from Egyptian and Mesopotamian artifacts when the dates were already known.In Egypt, Assyria, Babylonia, and Sumeria, there are "king lists" of who reigned and for how long.

Now clams take in ocean carbonate, which contains almost no C, so that it is no surprise today that a clam shell date appears ridiculously old.
This phenomenon, now well understood, only gives ages that are "all wet" for some samples that have been in water for some time.
The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.
The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.
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.Still others did this in Ireland, and others in England.Finally American researchers did this with bristlecone pine trees in Arizona. While many probably have not thought about it before, carbon-14 dating relates to Christianity and Judaism in interesting ways. Since there are many misconceptions about carbon-14 dating, this paper will explain the principle, the method, some early problems with it, and its current trustworthiness.Some clams were dated as having died 50,000 years ago, and they were still alive!
