Found this rather unusual stone whilst in Kent last week. I believe it could be from an ancient game of some sort. The markings are too regular for a natural occurence. The base is flatish to maybe keep the stone upright. Appears to be quartz, but not sure. It is in a good unweathered condition I have some pictures at the following address..........
I'd have to say this looks more like someones been using an electric drill! The holes look fairly fresh, almost white in the photographs (rather than accumulating a patina over time - and we should be thinking prehistoric if anything) and the linear marks look like someone tried to do a pattern with a drill but it just slipped around. Maybe I'm being too cynical or the photos are misleading?
I must admit, I have seen similar stones before, I tend to go with the game theory, clearly there is discoloration to what appears to be 'white Quartz". Has anyone tried to drill 20 plus marks into a 1cm stone before with an electric drill?
Yes a fosilized sea urchin it is, I came across a couple whilst out metal detecting!!! they were on top of a victorian coin, about 10 inches down, possibly used as a boundry marker in days of your?
