Dating dinosaurs and other fossils
By Scott Hershberger. Albert Ceolan Getty Images. On the Atlantic coast of the U. In Morocco, paleontologists excavated the fossils of a dinosaur that roamed Earth million years ago. How did the researchers determine these ages?
A trio of geologists has published what they called the first successful direct dating of dinosaur bone. They used a new laser technique to measure radioisotopes in the bone, yielding an age of millions of years. But this "age" was not only the result of a broken radioisotope system, it was contrived to agree with previously assigned dates for the samples. The scientists analyzed the abundance of radioactive isotopes of certain elements that had leeched into the edges of buried dinosaur bone from the San Juan Basin in northern New Mexico and southern Colorado. Their new technique involved first polishing a slice of bone and then shooting a laser beam onto its surface. The laser dislodged radioisotopes and other relevant isotopes, which were detected and counted.
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. But for some people, the discovery raised a different question. How do scientists know the bones are really 68 million years old?
How Do Scientists Determine the Age of Dinosaur Bones?
Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages. Knowing when a dinosaur or other animal lived is important because it helps us place them on the evolutionary family tree. Accurate dates also allow us to create sequences of evolutionary change and work out when species appeared or became extinct.
