Robert Schoch (written by his colleague) thinks that the Bosnian pyramid is a hoax :(

They say:

"the pavement is of natural formation and not manmade"

"The angle of the Pyramid taken from the air was to show the other sides that are not shown, as the only side that really looks like a pyramid is the only picture that is usually portrayed."

"we have many samples, none of which are showing ancient man made intervention to create a pyramid"
