Accelerator mass spectrometry AMS , a sensitive radiometric dating technique, is in some cases finding trace amounts of radioactive carbon in coal deposits, amounts that seem to indicate an age of around 40, years. Though this result is still too old to fit into any young-earth creationist chronology, it would also seem to represent a problem for the established geologic timescale, as conventional thought holds that coal deposits were largely if not entirely formed during the Carboniferous period approximately million years ago. Since the halflife of carbon is 5, years, any that was present in the coal at the time of formation should have long since decayed to stable daughter products. The presence of 14 C in coal therefore is an anomaly that requires explanation. The results of her correspondence are reproduced below:. Hey, I really lucked out with my first email to an AMS researcher. Got a very informative reply right away.

At four to five meters in length, the Greenland shark Squaliformes, Somniosus microcephalus is the largest fish native to the Arctic waters. Getting that big must take a while, and scientists have long known that these sharks grow less than one cm per year.

Aug 12,   Radiocarbon dating finds a Greenland shark that could be years old Proteins in the lens of the eye have been around for centuries. Shalini Saxena - Aug 12, pm UTCAuthor: Shalini Saxena. May 22,   Since the halflife of carbon is 5, years, any that was present in the coal at the time of formation should have long since decayed to stable daughter products. The presence of 14 C in coal therefore is an anomaly that requires explanation. The Solution: thefoodlumscatering.coms' Kathleen Hunt wrote an e-mail to a noted expert on AMS and 14 C dating. Carbon in diamonds: Refuting thefoodlumscatering.coms Published: 12 November (GMT+10) C S from United States wrote in: iStockphoto. I was looking at talk origins' little archive on Diamonds and C14 in summary. They say Radioisotope evidence presents significant problems for the young earth position.

Instead, the team used a modified radiocarbon dating technique that has worked before on other boneless animals: tracking the chronology of the eye lens. The eye lens nucleus is composed of inert proteins.

As a result, carbon-dating these proteins can help determine how long ago the shark was born.

talk origins goes over the creationist argument against carbon dating and other forms of dating in exhaustive detail. Their C argument is full of holes, and the dishonesty shown in leaving out contributing factors which completely change the data is evident.

One useful feature of the site is their voluminous list of FAQ files, where creationist and other pseudoscientific claims are carefully debunked. The sheer quantity of quality scientific information has led to the Talk.

Radiocarbon dating has been repeatedly tested, demonstrating its accuracy. It is calibrated by tree-ring data, which gives a nearly exact calendar for more than 11, years back. It has also been tested on items for which the age is known through historical records, such as parts of the Dead Sea scrolls and some wood from an Egyptian tomb. thefoodlumscatering.coms is a Usenet newsgroup (discussion group) which provides defenses for the evolutionary perspective against the creationist perspective. Its purpose is to be a place about the discussion of issues that relate to the origins of the universe, life on Earth, and civilization, with evolutionary biology, creationism, geology, and Velikovskyanism being the most commonly discussed subjects. Response Article This article (Carbon dating gives inaccurate results (thefoodlumscatering.coms)) is a response to a rebuttal of a creationist claim published by thefoodlumscatering.coms Archive under the title Index to Creationist Claims.

Origins archives being considered the Net's most significant clearinghouse of origins information out there, even being cited from time to time in science textbooks for further reading purposes. The TO archive also makes a point to link back to pages with opposing viewpoints, something not as common among creationist pages.
