Old Solid Round Stone Identification Assistance

[Ashland1]

I recently purchased this Old Solid Round Stone Approximately 9.072kg, 17.78W X 17.78H & Circumference 60.69cm at an estate sale and not sure what it is but the price was right. Does anyone know what this may be?

 

Thanks

Dolomite balls were used to make the pyramids and other large megalithic structures.   Bang two stones together and one does not need iron or steel hammers and chisels.  It has been shown that working sitting in quarry trenches can cut through anything using similar stones.   

 

In a leather sling, they also work well for catapult ammunition. 

 

Such things also make good ballast stones.  They pack well.
