U-series isotope data used to date a 130,000-year-old archaeological site in southern California, U.S.A.

This dataset includes tables with physical information and isotopic data that are used to calculate uranium-series ages (230Th/U method) and initial 234U/238U activity ratios on a suite of mastodon bones from the Cerutti Mastodon site near San Diego, CA area.
