Fossils are the remains of animals or plants that lived a long time ago. When we think of fossils, the first things that come to mind are the bones of dinosaurs; but a fossil can be anything. Footprints, flowers, even droppings; all of these things can be turned into fossils under the right conditions. A fossil only becomes a fossil when it has reached a certain age. Though there is no one age, a good rule is anything over 10, years old can be considered a fossil. The oldest fossils ever discovered are more than 3.

New science directly challenges the millions-of-years dogma scattered throughout the blockbuster movie Jurassic World. The spring edition of the Creation Research Society Quarterly CRSQ is a special issue that focuses on the investigation of dinosaur proteins inside fossil bones. The last article in the issue presents never-before-seen carbon dates for 14 different fossils, including dinosaurs. Because radiocarbon decays relatively quickly, fossils that are even , years old should have virtually no radiocarbon left in them. Jurassic World characters repeatedly mention "million years ago" in the context of their dinosaurs. In the movie, fictional scientists essentially resurrect and genetically redesign dinosaurs, pterosaurs, and even a giant mosasaur—creatures supposedly extinct for million years. The CRSQ study authors tested seven dinosaur bones, including a Triceratops from Montana, hadrosaurids, a cartilaginous paddlefish, a bony fish, and fresh-looking wood and lizard bones from Permian layers in Canada and Oklahoma.
Carbon dating dinosaur bones MD
This is an extraordinary discovery because Carbon has a half-life of only 5, years. As a result, any Carbon in a sample should decay to undetectable levels well under , years. This means that any fossil containing Carbon must be less than , years old.
This helps us to understand how that species fits into the evolutionary tree of change; when did they first appear and when did the last of their kind walk this Earth? Radiometric dating involves exploiting the radioactive decay of unstable atoms naturally present in the structure of bones and rocks. In old dinosaur bones, the material is buried under layers upon layers of sediment under high pressure. This means that it is almost impossible for isotopes to enter or leave the premises.
