Body Text (up to 1000 signs including spaces)	Inside “Mausoleum”, a small chamber (~2 x 3 m) of Petralona cave, the known human skull was found in 1960. In the same year its stalagmitic floor has being broken by the order of two Thessaloniki University professors, during a try of seeking the mandible and other postcranial bones. The chamber was subsequently excavated in 1977 by the author and several, more than a dozen of pieces were discovered inside the mixed up soil of the chamber. These fragments present a size from a few cm till 0,5 m in length, incorporating post-cranial broken human, but also animal, bones. On the basis of these stalagmitic pieces it is possible reconstruct (as with a puzzle) the ones existing Archanthropus’ stalagmitic floor. However various unfortunate events prevented their presentation earlier, something that becomes possible today.
