This is a great question...
Good question and one the journalist failed to mention. I know a bit about this subject (the dating of undatable stone). You can do that - if the
tools are found in a volcanic rock layer. In this case the story mentions the Kapthurin formation which is a basalt outcrop in Kenya near Lake
Bogoria, basalt is a volcanic rocka and can be dated using the Argon argon dating. Usually you date the rock layer above, below and containing the
subject. You then estimate based on those established ages.
So you don't date the stones themselves but the layers they are found in.
The dates actually obtain are 509,000 to 543,000 years - what 9-43 thousand years between friends?
A wiki link here en.wikipedia.org...
500,000 years is incredibly old...I mean had this date come up somewhere on a Great Pyramid stone, chances are it would've been thrown right out
Not to worry the limestone of the Giza quarries comes out at hundreds of millions of years in age. Of couse each layer, and there are dozens, dates
differently. You can see the layer pattern on the Sphinx.
More information of Giza limestone than you'd ever want
