Libby, the discoverer of the C14 dating method, was very disappointed with this problem. He understood that archaeological artifacts were readily available. After all, this what the archeologist guessed in their published books. Some believe trees are known to be as old as 9, years.

They use tree rings as the calibration standard. A lot of people doubt this claim for various good reasons I wont go into here. We believe all the dates over 5, years are really compressible into the next 2, years back to creation.

So when you hear of a date of 30, years for a carbon date we believe it to be early after creation and only about 7, years old. If something carbon dates at 7, years we believe 5, is probably closer to reality just before the flood. Robert Whitelaw has done a very good job illustrating this theory using about 30, dates published in Radio Carbon over the last 40 years.

One of the impressive points Whitewall makes is the conspicuous absence of dates between 4, and 5, years ago illustrating a great catastrophe killing off plant and animal life world wide the flood of Noah! I hope this helps your understanding of carbon dating. If you have any more questions about it don't hesitate to write.

Though the calibrated date is more precise, many scholars still use the uncalibrated date in order to keep chronologies consistent in academic communities. As the lecture detailed, it is only accurate from about 62, years ago to 1, A.

There is a sizable amount of time before and after that period that cannot be investigated using this method. Also, archaeologists cannot use their hands to touch the samples or smoke near them.

They risk seriously altering the result of the test. If an archaeologist wanted to date a dead tree to see when humans used it to build tools, their readings would be significantly thrown off.

This is because radiocarbon dating gives the date when the tree ceased its intake of Carbon—not when it was being used for weapons and other instruments! Since trees can have a lifespan of hundreds of years, its date of death might not even be relatively close to the date the archaeologists are looking for. Thorough research and cautiousness can eliminate accidental contamination and avoidable mistakes. The problem, says Bronk Ramsey, is that tree rings provide a direct record that only goes as far back as about 14, years.

Marine records, such as corals, have been used to push farther back in time, but these are less robust because levels of carbon in the atmosphere and the ocean are not identical and tend shift with changes in ocean circulation. Two distinct sediment layers have formed in the lake every summer and winter over tens of thousands of years.

The researchers collected roughly metre core samples from the lake and painstakingly counted the layers to come up with a direct record stretching back 52, years. Take the extinction of Neanderthals, which occurred in western Europe less than 30, years ago.

Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals' demise. The more accurate carbon clock should yield better dates for any overlap of humans and Neanderthals, as well as for determining how climate changes influenced the extinction of Neanderthals. She will lead efforts to combine the Lake Suigetsu measurements with marine and cave records to come up with a new standard for carbon dating.
