Comparison of preservation indices (API and QBI) and fragmentation (for elements with API > 1) for the skeletal assemblage contained within the soil and the one contained within the boots (boots associated with S3, S5, S6, S8 = S13, S11, S12, S15). The box represents the interquartile range (IQR) from the first quartile (Q1) to the third quartile (Q3), with a line at the median (Q2). Whiskers extend to the minimum and maximum values within 1.5 × IQR. Points outside this range are considered outliers and are pictured as circles, while X represents the mean.
