An archaeobotanical flotation photo gallery
Mary Anne Murray & her crew for flotation at Cubalel, Senegal near the Mauritanian border 1990.
Flotation from this West African Iron Age produced large quantities of fonio grains, pearl millet grains and pearl millet chaff (the involucre bases, which look like spikey hollow balls when charred), as below.
