Radiometric dating dinosaur bones dev patel dating

This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. The half-life of carbon-14 is approximately 5,730 years. dinosaurs the evolution alleges lived millions of years ago.Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).However, the method used by Simonetti and his colleagues determined that the New Mexico plant eating dinosaur was alive roughly 700,000 years after the surmised giant extinction event.

Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.The current method paleontologists use to date dinosaur fossils is a technique called relative chronology.The method estimates a fossil’s age relative to the known age of deposits of sediment in which it was found.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 64.8 million years old.The finding has caused a significant stir in scientific circles.Members of the Paleochronology group presented their findings at the 2012 Western Pacific Geophysics Meeting in Singapore, August 13-17, a conference of the American Geophysical Union (AGU) and the Asia Oceania Geosciences Society (AOGS).Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.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.
