The leading chronometric method for archaeology is radiocarbon dating (Figure 7.32). This method is based on the decay of 14C, which is an unstable isotope of carbon.

What chronometric dating method could you use to date this layer?

WHAT CHRONOMETRIC METHOD COULD YOU USE TO DATE THIS LAYER AND WHAT FOR WHAT DATE RANGE WOULD THIS METHOD BE APPROPRIATE? Because the bone is not yet fully fossilized, you could use radiocarbon dating which would be suitable for the recent past and back to about 50,000 years ago.

Which dating method is based on stratigraphy and the law of superposition?

Stratigraphy and the Law of Superposition Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.
