Absolute dating is the process of determining a specific date for an archaeological or palaeontological site or artifact. Some archaeologists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies a certainty and precision that is rarely possible in archaeology. Absolute dating is usually based on the physical or chemical properties of the materials of artifacts, buildings, or other items that have been modified by humans. Absolute dates do not necessarily tell us when a particular cultural event happened, but when taken as part of the overall archaeological record they are invaluable in constructing a more specific sequence of events.
By: Tracy V. Wilson Updated: Mar 31, 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.
How Do Scientists Determine the Age of Dinosaur Bones?
Earth Science, Geology, Physics. Take a look at a globe or a map of the world and you may be impressed by what you see. Towering mountains, deep oceans, vast continents, and sprawling glaciers—they make Earth what it is today. Scientists have calculated the age of our planet to be approximately 4.
If you will study the relative age of a rock layer, which indicator below is the more appropriate to use? Radiometric dating is used to estimate how geologic rocks are formed and infer the ages of fossils contained within those rocks. In which of the given rocks is Radiometric dating least useful?
