7,000 year old city

I would like to know what means was used to date it, but this article is on a European culture that was in Germany, Austria, etc. about 4800 BC. Note: That is about 4000 years before Dielli, the main character in my trilogy. (Which right now, 8/6/05, if a book and a half.)

Note: Cronaca says the source has not always been accurate. Which is good to know, since I was wondering that very question in class this morning.
