Stable isotope values through time for four Great Basin desert mice

Stable isotope data from mouse bone collagen, arrayed by stratum at Two Ledges Chamber, NV. Stratum age represents years BP unless otherwise noted. AMS 14C dates from bone collagen were calibrated using OxCal 4.1 and the IntCal 09 calibration curve. Age estimates represent the highest probability peak obtained from the Bayesian posterior probability distribution associated with date calibration. Age type refers to the following: (a) known collection year, (b) known by AMS 14C dates, (c) inferred from a combination of AMS 14C dates and spline function estimate, (d) undated stratum age inferred from a spline function. δ13C_2013 indicates carbon data Seuss-corrected to 2013 CE.
