At UCL today talking archaeobotany with Louis C and his PhD supervisor Dorian F.
In the course of his participation in the Crossroads fieldwork, Louis took samples from 12 sites and 28 test pits and he has been looking for pieces of charred plants within them; see a report by Sam here. Below, sampling trench IV at Birnin Lafiya in February 2012.
Now all these samples are being examined in lab conditions here in the UK. Louis is looking at changes in the archaeobotanical remains across time, seeking to characterise what people grew and to identify shifts in the plant assemblages. Today we talked about maize, bananas, sorghum, shea butter nut, wild grasses, millet, tomatoes and mangoes. Each of these likely entered this part of Benin at a different time.
