Carbon 14 dating is a type of
Here is a discussion of this and related finds by Brian Thomas, a creation oriented author: verified and extended protein identification in a duck-bill dinosaur that Mary Schweitzer’s team had described in 2009.These two new finds join dozens of others published over the last half-century, but evolutionary scientists still have a hard time accepting that these fossils retain original biochemicals.Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died.
Thus a sample that dates to 40,000 years by C14 dating still has about 7 billion C14 atoms per mole of carbon.Organic matter in the fossil record generally dates by carbon 14 (C14) dating to about 20,000 to 40,000 years. Many creationists believe that radioactive decay was faster in the past.Other radioactive dating methods such as potassium/argon (K/Ar), rubidium/strontium (Rb/Sr), uranium/lead (U/Pb), thorium/lead (Th/Pb) and others that are based on decay of longer-lived isotopes often give ages in the millions or hundreds of millions of years for these fossils. However, in this talk I want to concentrate on reasons to believe the C14 dates are more accurate and that they give evidence that all life on earth is very young.Recent finds of Mary Schweitzer are also relevant for the dating of ancient bones.Mary Schweitzer, a professor at North Carolina State University (North Carolina), has found soft tissue and protein in dinosaur bones.
