The large sample sizes and excellent preservation of collagen in the bones at the La Brea tar pits, California, made these C14 measurements possible, but proved to be too expensive and impractical for the large samples required with conventional dating methods.

Discovery of Radiocarbon Dating accessed October 31, They were similar to radiocarbon dates for ice-age megafauna such as Siberian mammoths, saber tooth tigers of the Los Angeles LaBrea Tarpits, sloth dung, and giant bison.

To confirm the feasibility of dating the shroud by these methods an intercomparison, involving four AMS and two small gas-counter radiocarbon laboratories and the dating of three known-age textile samples, was coordinated by the British Museum in This new methodology required only 1 mg instead of 1 g of carbon.

Both bones did in fact contain some collagen. It can make up from 1 to 6 percent of muscle mass. The results they obtained indicated this was the case.

Chemical Pretreatment Methods

The program entitled "Did the Ancients See Dinosaurs? More recently to aid in the understanding of the series of reactions that can take place during diagenesis and pretreatment, van Klinken has used sample yields during enzymatic cleavage to screen the degree of cross linking.

Soon after Libby In the s and 60s, people blew up alot of nuclear bombs, and one thing that happened because of this was that alot of radiocarbon was created in the air artificially.

In this method, the carbon sample is first converted to carbon dioxide gas before measurement in gas proportional counters takes place. The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.
