    What information can radiocarbon dating tell paleontologists

    Originally, bones were used to determine how old a person was, their race, and whether the remains were of a male or a female.

    Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

    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.

    The Wheeler Formation has been previously dated to approximately 507 million year old, so we know the trilobite is also about 507 million years old.

    But, how can we determine how old a rock formation is, if it hasn’t previously been dated?
