Radiocarbon dating (AMS) of Marshill site (Eastern Cape)_Export permit

I would like to send 12 radiocarbon samples to two different laboratories. In order to compare methodologies and results of two different laboratories. My plan is to send 6 radiocarbon samples to Poznan Laboratory in Poznan (3 bones and 3 charcoal) and 6 radiocarbon samples to Oxford Laboratory (3 bones and 3 charcoal). The faunal remains are diafisis fragments nonidentifiable and the charcoal remains are small pieces that have been already analyzed. All the material is coming from two different Late Stone Age layers of the site of Marshill (Eastern Cape, South Africa).
