What vexed archaeologists back then was: Where did these pots come from? Where they produced locally or were they brought to the islands?
In the latter case, this could hint at a trade network linking the Mediterranean. The clue to answering this question lies in the single-celled organisms found fossilised within the clay itself.
Researchers Dr Ing. John Charles Betts and Dr Catriona Brogan examined the 'foraminifera' found within the clay in order to identify its provenance and gain a better understanding into ancient Neolithic society.
