I've been picking up round rocks in indian camps for sixty years. Here are some possibilities for uses of such. Three of them strung together produces a bolo, two of them incorporated into an oak handle makes a handy head-knocker and a small one mounted on a handle makes a effective drum stick. Anthropologists agree that man's first musical instrument was probably of a percussion type and may have been anything from banging two rocks together to beating on a hollow log with a club. There is no way to know if Clovis man made and used drums but if he did I kind of like to believe that it may have looked like this.

I see them all the time but I never pick them up... I always figure they threw them from a sling for small game like rabbits.

Good thinking Red, Like "drills"..."game ball" definition doesn't necessarily mean they were used for one purpose, like exclusively for a game.

I like the drum & head thumper concept. As good a weapon as the Bolo is thats my last choice for most parts of TX. Restrictive vegetation ( tall brush )would severely limit it's use.

neat pics, Tks
