They were made out of Granite and Diorite!! The only known stone harder then those is DIAMOND!!!
I assumed he didn't dwell on this because it is in fact not true (again, facts are appreciated, Slayer.)
The vast majority of stones shown in pics in this thread (and present at both sites) are Red Sandstone.
There is no Diorite there.
The hard stone present at the site is Andesite.
Diorite, Andesite and Granite are all pretty much the same stone, with slight differences in formation.
You don't need a harder stone to shape a stone.
As an aside, your comments about "contamination" leading to faulty C14 dates is outrageously impossible. But no matter.
Also - Posnanski's dating method involved him assuming
the positions of certain structures that were no longer there. That might be okay for a
ballpark figure, but as you yourself noted, the archaeoastronomy used was by nature extremely succeptible to large errors if the "alignments" were
only a degree or two off (which can easily happen if the structure you're "aligning" with isn't actually there anymore!)
Another site has been located next to Lake Titicaca that dates to the same period, BTW.
