An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new research from North Carolina State University. A relative age simply states whether one rock formation is older or younger than another formation. Originally, fossils only provided us with relative ages because, although early paleontologists understood biological succession, they did not know the absolute ages of the different organisms. The Society of Vertebrate Paleontology is a non-profit organization dedicated to professional vertebrate paleontology.

Cart 0. A technician of the U. Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. Originally fossils only provided us with relative ages because, although early paleontologists understood biological succession, they did not know the absolute ages of the different organisms. Different isotopes of the same element have the same number of protons in their atomic nuclei but differing numbers of neutrons.
