Document Summary
This chapter is about how archaeologists date things. Absolute dating: such dates are expressed in speci c units of scienti c measurement - days, years, centuries or millennia - but no matter what, they all point to a speci c year or a speci c range of years. Relative dating: this was used before 1950s - it is vague and not as precise - so e. g. pyramid at saqqare is earlier than __ but later than__ Vital to relative dating is the index fossil concept. This is, the idea that strata containing similar fossil assemblages are of similar age. This was presented by william strata" smith and helped geologists locate time of different rocks. This also helped solve archaeology"s problem of dating. Geology"s law of superposition could indicate which artifact types or styles were older than other forms in particular sites.
