" It's a surprise that it's come from so far away, " said University of Exeter archaeologist Susan Greaney, who was not involved in the study.

“令人惊讶的是，它来自如此遥远的地方，”并未参与这项研究的埃克塞特大学考古学家苏珊·格里尼说。

Greaney said the number of visitors was on the increase at the time Grey lived there because cars were becoming more common and Stonehenge was seen as a perfect day out.

Greaney 说，在 Gray 住在那里的时候，游客的数量在增加，因为汽车变得越来越普遍，巨石阵被认为是完美的一天。
