Abstract
The combined use of microscopy and organic residue analysis on stone tools from the Early Mesolithic site of Star Carr, England, has tentatively identified residues consistent with pine (Pinaceae family) tree compounds. Microscopic residues from nine stone tools, originating from several locations and dated between ca 9300-8500â¯calâ¯BC, were found to contain traces of diterpene compounds, consistent with dehydroabietic acid (DHA), 7-oxo-dehydroabietic acid (7-oxo-DHA), and dehydro-7-dehydroabietic acid (dehydro-7-DHA) through analysis by GC-MS. Sediment samples taken directly underneath each tool did not contain any of the above compounds associated with Pinaceae. The results suggest the use of Pinaceae resin by Early Mesolithic hunter-gatherers in this region.
