112 pound sphere hand made or geo artifact native American artifacts Boston Indiana

[Ross1975]

Hello and greetings to all. I was attending a estate auction when I came upon this 112 pound or right around that weight this giant hand chipped round stone. Of course I bought it. My question is what is it? And is it native American? I believe it is because there's a small groove in it as seen in the pictures. What would be the value on something like this? Please help. Thanks and kind regards, Robert

This may help some understand they are natural...

i don't think its native American made.

There is no documented items like this that I have ever heard of in 56 years. Nor have I ever seen anything related like this and this size at any relic shows.

to me, it looks like one of the large limestone type ornaments made in the late 1800's - early 1900's that can sometimes be seen in old park areas on top of a column or the like.

If memory serves me correctly, I am pretty certain that Barney Rubble and Fred Flintstone were avid bowlers. You will have to consult with an expert, but I am pretty sure you have found one of their bowling balls. Nice find!
