Abstract:
... Categorical variables identifying microscopic features of cut marks produce high accuracy in discrimination of bone surface modifications, but are vulnerable to variable degrees of inter-analyst subjectivity. Metric analyses of cut mark width and depth are presented by Merritt et al. (2018) as a more objective method of identifying cut marks. However, this uni(bi)variate method has shown very high ...

Abstract:
... Developments in methodological approaches to high-resolution morphometrical study of cut-mark morphology further our understanding of butchering activities. Identification of micro-morphological variability between different taphonomical alterations on ancient bone allows detection and comparison of bone-surface modifications and associated taphonomical agents and activities. By taking a geometric ...

Briefly, layered double hydroxide (LDH) sheets were first modified with polymethylhydrogen silicone oil (PMHS) to give superhydrophobic LDH sheets (SHP-LDH). Subsequently, the SHP-LDH sheets were immobilized at dif ...

Abstract:
... The archaeology of fire is a developing field. One challenge centers on equifinality: distinguishing the affects of wildfire versus anthropogenic fire. Especially where evidence for control of fire by humans in the early Pleistocene remains debated, there is little consensus regarding what constitutes clear evidence of human-control. Another concern is preservation bias, which reduces clearly iden ...

In fact, stone technology continued to be used everywhere until at least the end of the Early Bronze Age, and even until the end of the Late Bronze Age in specific areas. This is especially true for Greece where lithic raw material and/or tool networks were ...
