• Resumen

  • Fish represent an important resource to people living near water sources. However, the visibility of fish remains within the archaeological record is generally considered to be reduced compared with other taxa, in part because of their greater susceptibility to natural processes of taphonomic attrition. This experimental pilot study focused on testing the durability of fish elements by comparing the survivability of denser post-cranial elements with less dense cranial elements in a range of pH solutions. Data obtained from these observations were subjected to a statistical analysis that revealed several trends. No significant difference was observed between the survivability of cranial and post-cranial elements, however, a significant difference was noted for the impact of pH on element survivability. In general, both more acidic and basic environments were observed as detrimental factors for fish element survivability.
