Researcher Martin Brennan at Carrowmore 51, Christmas 2009. The engraving is highlighted using Photoshop. A newer and more detailed image of the engraving was taken by local archaeologist Robert Hensey using a new photography technique. Scale may not be exact.
The oldest date recovered so far from Carrowmore, 5,400 B.C., is extremely early and most Irish archeologists have dismissed as being too old. The general opinion today, based on Burenhult's research, is that Carrowmore is an early site from around the time mesolithic hunter-gatherers were turning into neolithic farmers.
In 2003 an archaeology seminar called 'Stones and Bones' was held in Sligo in honour of Michael O'Kelly, the excavator of Newgrange. Goran Burenhult, who was invited to dig at Carrowmore by O'Kelly, hosted the seminar; the dates below are his latest published work on Carrowmore, and are somewhat re-calibrated from the extremely early dates.
