I had planned to devote a long article to the numerous artifacts and mostly pseudo-artifacts found in 2006 and at the beginning of 2007 by Mr. Osmanagic’s team, but Stultitia has been more swift and made two excellent posts on the English blog of the Anti-Pyramid Web Ring (en). So that I will just make a short summary and send the visitor to Stultitia’s posts.
Let’s begin with the "real" artifacts. It appears that the Osmanagic team has found quite a lot of them, but, unfortunately, they had absolutely no link with the "pyramids", so that these findings never received any attention, any publicity, from the Foundation: not a single photograph, not a single mention can be seen on the official website. How then is the existence of these artefacts known? for the most part by the testimony of some members of the team who participated in the excavations (Nancy Gallou, Silvana Cobanov, and particularly Dr Barakat). So they mention this or that finding, that is never officially confirmed by the Foundation, and of which we loose later the trail. Stultitia gathered in her post "The missing artefacts" (en) a series of such findings: along with the skeleton mentioned in the geologist Nukic’s report (see here), of which, Mr. Osmanagic admitted in a radio show during the month of April 2007, the trail is lost without any datation made, there are neolithic tools, fragments of medieval ceramics, iron nails, inscriptions maybe in medieval Bosnian cyrillic, various organic material. To add to the examples gathered by Stultitia, here are some photographs found on the Foundation official website on the 4th of May 2006 that have later disappeared from it :
As Stultitia says, all these finds are "consistent with the existing knowledge on the archaeology of the Visoko region" (presence of a quite dense medieval settlement on the slopes of Visocica, neolithic sites near Visoko).
Why is it that the Foundation team never published these finds and even, one could say, they chose to hide them? Probably because not only is there not a single one item that could support in any way Mr. Osmanagic’s hypothesis, but on the contrary they confirm the fears of the local archaeologists about the serious threats of destruction of real archaeological sites. The single real artifact that the Foundation did not hide, and even claimed as decisive, is the rectangular structure on Pljesevica (see here), presented at a time, with a lot of publicity, as "the entry to the pyramid". We still don’t know what it is exactly, nor what is the age of this structure .
However the Foundation claims to have found artifacts, both on the "pyramids" and in the tunnels. During all the 2006 season were regularly published on the official website photographs of stones with strange shapes, usually without any comment: it was not officially claimed that they were artefacts, but they were presented as important objects. A few examples:
The last photograph above appeared in one of the delirious texts (bs) by Goran Cakic, where the stone is described as presenting an engraved bird, or maybe a flying dinosaur...
Another stone, that appears today like that:
on the Foundation website, was on the 4th of September 2006 presented like that:
Of course, when you have a pyramid you should have an obelisk!
Let’s mention also, among the oldest peculiarities, this "processed stone" shown in Mr. Osmanagic’s book:
with circular motives that the geologist Paul Heinrich interprets (en) as an instance of natural "Liesegang banding" or "Liesegang rings", colored bands or rings made by the diffusion and the precipitation of iron oxydes.
So, during the year 2006, the Foundation "suggested", but never claimed officially that these strange stones were artifacts. But then, at the beginning of the year 2007 appeared on the Foundation web site, and particularly in a "report" made by Mr. Muris Osmanagic (bs)  (see below) a great number of extraordinary "artifacts". Stultitia gathered these pseudo-artifacts in this post (en); I’ll let the reader enjoy the "monumental cow", the "one-tooth horse", the "three-headed dragon", the "serpent", as well as the "two-sided human foot" that was used, according to Mr. Osmanagic Senior, "most probably as a measure unit to the pyramid builders". I will add to Stultitia’s collection the last items appeared on the website, the fish (see also here):
and the... uh... well, I’ll leave to the reader the finding of a name :
