Abstract

Molecular preservation in the archaeological record has been recognized and documented inseveral cases. The association of protein, lipid and DNA remnants on artifacts requires anew level of care in the excavation and conservation of materials. The removal of blood from a series of experimental tools made of quartzite and obsidian is shown by a simple water washing procedure. Attempts at stabilizing the blood with time and temperature did little to alter its removal. It is suggested that the normal procedures utilized onsite andin postexcavation treatment can be detrimental to the recovery of information at the molecular level.
