AINW Conducts Blood Residue Analysis
on 250,000-Year-Old Tools from Jordan

AINW analyzed ancient tools from Jordan for Dr. April Nowell of the University of Victoria. The tools were from a sealed deposit that was 250,000 years old. Blood protein residues were detected on 17 analyzed tools. The positive results were from bovine, camel, duck, horse, and rhino. The technical article was published in the Journal of Archaeological Science.
