Lap Pestle???

[gtfd47]

Heres the deal.....Digging a drainage ditch and I flip up this boulder. Definately out of place...thought it was a river stone @ first, but no rivers around...area has a Native american history. Stone is granite and is unbelievably symetrical and has the appearance of being "worn down" that way. Looked up some things and found a native american lap mortal and ball pestle...Im thinking thats what it is. Looking for some opinions/guidance
