Thanks for that link.

Thought: Crystal Skulls!!!
Are they connected in some way?

Hypothesis:
Lets say , before the big tsunami and the floods came, and raised the sealevel , sinking all the great cities, and Atlantis below the ocean, wiping out and resetting life on Earth, maybe the whole world was a big Pyramid culture based society.
So they knew everything about Pyramids , how to use them, what they meant. Maybe the crystal pyramids were special, in some way, and were an accesory to the great Giza Pyramid.
Maybe these crystal pyramids were the center piece of all the pyramids all over the world.

And maybe somehow the crystal skulls figured in this.
Note the sonar illustration of the pyramids in the clipping.
ITs not like the Giza pyramid.
There seems to be a sort of housing on the apex.
Was this where the crystal skulls were placed?
If not, then why construct a housing at the apex of the pyramid??

Im foaming at the mouth here, but am just posting what comes to my mind.
