14 repeat steps 12 and 13 using the uranium2 38

This preview shows page 2 - 3 out of 3 pages.

14. Repeat Steps 12 and 13 using the Uranium2-38 detector to estimate the rock ages.For fossilswith no remaining C-14 signal, use the rock ages to estimate fossil ages in the same layer.15. Summarize how C-14 and U-238 dating together can be used to determine fossil ages.
