Also I spotted a whole caseful of these http://www.museum.ie/en/exhibition/gallery/irelands-gold-photo-gallery.aspx?image=9e09081e-117a-4821-ac42-cfd2418ea081
which was quite a surprise as virtually identical things have been found near to where I live in South West england (I thought of Moss in particular who might be interested). So I suppose they must have travelled from Ireland originally (or if not, certainly the style did) - I'm sure there are ways of testing the gold to see where it originates.
Superb, and I would urge anyone in the vicinity to go and visit, and indeed it makes a very good reason to go to Dublin full stop. (and you can go and see the poor thylacine in the natural history museum, which is also marvellous).
Poor creature was it stuffed or just bones now ;) tis a wicked world we live in making creatures extinct...
