I know what you mean about the scratching posts. They're a bit confusing. There are a number of stones that I've visited that I've subsequently found out aren't prehistoric. On the whole I just haven't listed them.

I usually place some trust in the NMRW (National Monument Record of Wales), but I wonder whether I am a bit too trusting at times. Just because the records say something isn't prehistoric, is that correct? What evidence do they have to date the site? If I can find the time I'll pay a visit to the NMRW library and dig deeper into their records. This usually helps, but it's very time consuming. In a lot of cases the records of different archaeological bodies contradict each other. If one or more think a site *is* prehistoric, then I tend to stick it up on TMA.

Hope this helps.
