Arare 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.
