I was just there. Doesn't say much does it. That site could be so good if they just pressed a few more keys when adding an entry!

"The northern area adjacent to Trench 2 was characterised by a relatively sterile sandy silt (0.1m in thickness) which contained few artefacts. However within the silt was a small group of cattle bones C14 dated to 5510 BP. Towards the base a small cache of polished stone axes was recovered (5 axes were found)."

The odd part is 'towards the base', not 'at the base'.

I'm also curious to know why 3500 bce is considered by some to be before the Neolithic, when Ireland's Neolithic was 2000 years old by then.
