Carbondated dinosaur bones are less than 40, years old. Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed. Carbon C dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22, to 39, years old. Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.

How To Date A Dinosaur Fossil | The Skeptical Chemist
February 16, By William G. Gilroy, University of Notre Dame. Antonio Simonetti, a research associate professor in the Department of Civil Engineering and Geological Sciences at the University of Notre Dame, is the coauthor of an important new paper describing a novel method for age dating dinosaur fossils. Simonetti and colleagues from the University of Alberta used a U-Pb uranium-lead dating technique to analyze a fossilized dinosaur bone discovered in New Mexico. In a paper in the prestigious journal Geology , the researchers discuss their method and reveal that it determined that the femur bone from a giant hadrosaur dinosaur was
How Do Scientists Determine the Age of Dinosaur Bones?
When paleontologist Mary Schweitzer found soft tissue in a Tyrannosaurus rex fossil , her discovery raised an obvious question -- how the tissue could have survived so long? The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains , decomposes. Only hard parts, like bones and teeth, can become fossils.
Creationists bring up Carbon 14 dating of dinosaur bones all the time. This shows a lack of basic understanding of how the method is used and what material it can be used to date. Carbon 14 is used to date things that were once living and in equilibrium with the atmosphere. Here is a brief explanation of how the method works from http:
