Figure 7.

Bivariate wavelet coherence plot showing the correlation of cut mark damage on the proximal, midshaft and distal sections of the humeri of the Sonai ethnoarchaeological dataset and the experimental dataset. Arrows indicate that in one of these two high-correlation areas, both series are in phase (i.e. they covary together in the same right direction). The thick black line designates the 5% significance level against red noise and the cone of influence. The thick arrows in between histograms indicate loci of the high correlation between both series.
