Some of the artefacts recovered are stored in the National Museum of Ireland, but most of the bone assemblage was transported to Cambridge University, where Macalister's father, Alexander, was a Professor.

The original excavation mistakenly dated the monuments as Bronze Age structures, but the new study has shown that the sites were in use between c. 3,500 and 2,500 Cal.

Of 22 stable isotope samples, the majority indicated that the dead had grown up in a carboniferous limestone region, probably close to Carrowkeel.

The DNA genomes assembled from six individuals indicated ancestral origins in Anatolia, and greater affinity with the Mediterranean than the Danubian expansion of early farming in Europe.

One of these outliers is situated at the north end of Lough Arrow and NW Carrowkeel; the giant passage tomb, Heapstown Cairn.

This is part of the legendary Moytura, a site of battles between the Tuatha Dé Danann, the ancient gods of Ireland, and the demonic Fomorians.

[8] There is evidence of recent treasure hunting at some tombs, apparently by people unaware that these "stone age sites are over 5,000 years old and pre-date the use of metals in Ireland".
