The 85-7-7-1 a b c d question
This is an abbreviated question that use to get asked in Archaeology 101 and higher courses some years ago. This is a simplified version.
You are at an excavation, you have been successful!
You have 85 sources of dates that come in at 4,000 BP +-200 years
You have 7 sources of dates that come in at 3,750 BP with +- 500 years
You have another 7 sources of dates that come in at 4,250 BP with +- 500 years
Sources of dates are from pottery, Radiocarbon, Dendrochronology, Thermoluminescence, Optically stimulated luminescence, Archaeomagnetic, Lead
Corrosion, Amino acid dating, Obsidian hydration and Rehydroxylation pottery comparison, etc
The above applies to all four the following alternatives which are:
A. You have one date that is to 12,000 BP with +- 1,000 years
B. You have one date that comes up as modern
C. You have a item that cannot be dated
D. You have an item that dates to 6,000 BP but with a range of +- 2,500 years
So what do you report as the age of the site for the following situations A, B, C and D?
