The absolute age of a fossil.
Radiometric dating measures radioactive decay to give a numerical age (years) for rocks or minerals. Note: fossils themselves are often dated indirectly by dating volcanic layers above/below them; different isotopes work for different age ranges (e.g., C-14 ~ up to ~50,000 years; K-Ar, Ar-Ar, U-Pb for much older ages).
