news about medieval skeletons

[tempestsarekind]

"Skeletons unearthed by Gloucester Linkages workmen"
http://news.bbc.co.uk/2/hi/uk_news/england/gloucestershire/8668891.stm

and one whose use of "possibly" in the headline confuses me:
"Medieval African possibly found buried in England"

(I mean, he could be possibly medieval, or possibly African, but possibly buried? Presumably that's the part we know for certain.)
