“…Differences have also been noted when using CI and C/P (see Table 18.2) to examine pathological and nonpathological human bone. The presence of tuberculosis and syphilitic lesions caused a decrease in CI (but an increase in C/P) values (Nagy et al, 2008; see Figure 18.1, where it can be seen that these values also overlap with those for low-temperature burnings). This is perhaps to be expected considering that both pathological conditions result in remodelling of the bone surface, but it does have implications for sampling bone material beyond the anatomical location discussed by Thompson et al (2011).…”

“…The third major consideration is that whilst some workers may debate the application of CI to heat-altered bone, perhaps the key issue with the CI is that, as Piga et al (2008b) note, it Heat-induced changes to the Crystallinity Index using the FTIR-KBr method (data compiled from King et al, 2011;Koon et al, 2003;Lebon et al, 2010;Munro et al, 2007;Nagy et al, 2008;Piga et al, 2008a;Pucéat et al, 2004;Schiegl et al, 2003;Schwarz et al, 2009;Sillen and Morris, 1996;Stiner et al 2001;Thompson et al, 2009). The boxes represent 95% ranges, whilst the lines represent the total range of values, horizontal bars are the means and circles/asterisks are outlier values.…”

“…Diagenesis results in the growth of large crystals at the expense of smaller ones (Brock et al, 2010), and this can occur as the result of both weathering and fossilisation (Brock et al, 2010). Diagenesis can result in the bone mineral converting into a different form (such as francolite with the chemical signature Ca 5 (PO 4 ,CO 3 ) 3 (F); Nagy et al, 2008;Schiegl et al, 2003).…”

“…Theoretically, postdepositional phenomena result in increasing loss of the organic component [21,22], so it was expected that the more ancient archeological bones had a smaller preservation of CC in comparison to the more recent forensic bones [39]. That would explain why the spectrum of forensic bones had a much more intense band of the amide I (collagen).…”

Rather yield than break: assessing the influence of human bone collagen content on heat-induced warping through vibrational spectroscopy

et al. 2016

Warping has been used to determine the pre-burning condition of human skeletal remains. In the literature, this modification has been associated more often with the burning of fleshed and green bones, but it also arises during the burning of dry bones. The objective of this paper was to assess if bone collagen content has a significant effect on the occurrence of warping in a sample of experimentally burned human bones. The presence of collagen was analyzed in two different samples through a vibrational spectroscopy technology-FTIR. One of them was composed of 40 archeological bones from the seventeenth to twentieth centuries AD. The other one was composed of bones from 14 skeletons belonging to the 21st century identified skeletal collection. The results confirmed that the amide I band assigned to the collagen was much more intense in bones presenting heat-induced warping. Nonetheless, although significant (p = 0.040), the collagen content was not as useful as other variables to the regression model we proposed for explaining warping. Factors such as the maximum temperature (p < 0.001) and burning time (p = 0.001) contributed more significantly. Results demonstrated that the mere preservation of collagen is not enough to explain warping. Burning dynamics seem to have an important role as well although we failed to clearly document its specificities. Other factors such as the asymmetric distribution of collagen and other components within bone, the gravity force, the shape of the bone, and the position in which it is burned may also play an important role on heat-induced changes and require further analysis.

“…The CI values in modern unaltered bone typically lie around 2.50-3.25, but will increase as crystal structure becomes more ordered (Munro et al, 2007;Nagy et al, 2008;Nielsen-Marsh and Hedges, 1999;Shipman et al, 1984;Stiner et al, 2001;Trueman et al, 2008). The crystal structure of bone can be seen to alter very slowly towards a more ordered composition with an associated increase in overall crystal size following death (Bartsiokas and Middleton, 1992;Munro et al, 2007;Olsen et al, 2008;Surovell and Stiner, 2001).…”
