Mark Rose at Archaeology.Com throws cold water on the Bosnian pyramids:

And there it is. A self-described archaeologist, who believes the Maya and others are descended from Atlanteans who came from the Pleiades, has been accepted as a legitimate researcher by many news outlets. His ideas of early pyramids in Bosnia, which is simply not possible, has been accepted as a major discovery. How could this happen?

If you want to categorize this farce, it seems a standard-issue "amateur/maverick confounds establishment with great discovery" story, which no doubt makes it appealing to uncritical reporters looking for a big story. This kind of tale is a staple of the pseudoarchaeology or fantastic archaeology genre. And the term "pyramidiot" has been applied to those obsessed with pyramids and who offer strange interpretations of them on websites and in books and televsion programs.
