Nuts nearly nine thousand years old have been found in the north of Skye, and are thought key the key to learning more about our hunter gatherer forebears.

The discovery of hazelnut shells was made during the five-day archaeological excavation beside Staffin Bay in September. University of the Highlands and Islands (UHI) archaeologists were investigating a suspected Mesolithic structure, in collaboration with the local Staffin Community Trust (SCT).

Radiocarbon dates have now confirmed what was unearthed dates to the Mesolithic period, towards the latter half of the seventh millennium BC, and further major digs are now almost certain.

Two fragments of charred hazelnut shell both returned dates of circa 6800-6600 BC (calibrated). The hazelnuts were recovered from soil samples from the lower part of the sequence at the site, suggesting human activity may have occurred over a long period of time.

The excavation also yielded a fragment of worked bone, and several thousand flints which are being analysed.

While the structure at the site is likely to date to the post-medieval period, confirmation of Mesolithic dates for the layers below it could provide further clues about life in the area over 8,000 years ago.

The new dates are a bit earlier than the earliest dates from material recovered at another nearby site in the 1990s, at An Corran rock shelter. Experts say both sites were essentially contemporary, with many dating to this period along the Staffin Bay coastline.

Dan Lee of UHI's Archaeology Institute UHI, said: “We are really pleased to have such convincing Mesolithic dates from the site. This hints at the huge potential for additional excavations in the area and presents a great opportunity to understand life in the Staffin area during this period.”

SCT director Dugald Ross said: “The lab confirmation of human activity in the local area close to 9000 years ago is a huge bonus to all who took part and we eagerly await the next phase of research.”

SCT and UHI are to discuss how further work can be carried out in the Staffin area following this exciting discovery from the community-led project, which was attended by more than 200 people, including pupils from Staffin and Kilmuir primary schools.

The project was funded by the Scottish Funding Council via Interface Scotland, Highland Council and the Carnegie Foundation of New York.
