Radiocarbon dating can take you back 40,000 years. NAU researcher Darrell Kaufman is going much, much further. 🦴🔬

NAU Regents' Professor Darrell Kaufman runs one of just a handful of labs on Earth specializing in amino acid geochronology—a method that can unlock the ages of fossils dating back to the last several ice ages. It's cutting-edge science happening right here in Flagstaff.
