A. A rare find of carbon containing soft tissue (biological tissue, such as proteins) in a T-rex dinosaur fossil bone that is thought to be 65
A. A rare find of carbon containing soft tissue (biological tissue, such as proteins) in a T-rex dinosaur fossil bone that is thought to be 65 million years old has recently been discovered by paleontologist Mary Schweitzer (Fields 2006). You have been asked to analyze a sample of the tissue for carbon-14 dating. The activity of the sample was found to be 8 x 10-5 disintegrations per second. An equal mass of fresh sample of human tissue was found to be 15.200 disintegrations per second. The half-life of carbon-14 is 5700 yr. Calculate the age of the dinosaur tissue from the data you acquired.
B. Is the date you calculated above valid for this type of analysis? Why?
C. Read the paragraph below. Does your finding support, refute, or not do either for Creationist theory? Explain why. (5 pts)
"Young-earth creationists also see Schweitzer's work as revolutionary, but in an entirely different way. They first seized upon Schweitzer's work after she wrote an article for the popular science magazine Earth in 1997 about possible red blood cells in her dinosaur specimens. Creation magazine claimed that Schweitzer's research was "powerful testimony against the whole idea of dinosaurs living millions of years ago. It speaks volumes for the Bible's account of a recent creation."
