In one of the Late Mesolithic graves at Skateholm, Sweden, dating from 5500–4800 BC, were buried a woman together with a newborn baby. Altogether 32 perforated wild boar (Sus scrofa) teeth and traces of red ochre pigment were found in this grave as well. These were interpreted by us as a rattling ornament decorating a baby pouch of leather coloured with red ochre. We made an experimental reconstruction and found out that the teeth function well as a rattle when moving the carrier. The reconstruction currently is on display in the European Music Archaeology Project’s travelling exhibition on archaeological instruments.Peer reviewe
