Raman spectrum of modern pine (a) compared with highly degraded wood from the Neolithic site of Anargyroi, Greece (b, c and d). Arrows indicate the remaining characteristic peaks of lignin and carbohydrates. The loss of peaks at 1341 cm−1, 496/521 cm−1 and 897 cm−1 indicate the complete loss of carbohydrates. Lignin is also highly decayed, with loss of the peak at 1190 cm−1 indicating loss of phenol
