It is usually difficult to say without hands on examination. Limestone or sandstone rock? Probably would need closeup and well as rock type.

The wavy imprints on the bottom left kind of remind me of weathered ripple marks(from streams)- they are usually preserved in clastics such as sandstone or siltstone.

real hard to say....the left edge looks worked. hmmmmmmm..... those lines look too uniform/and not uniform to be mama nature.

any more info on the area it was found in. might help.

ll36, It was found along the banks of the neosho river in kansas. It was unique in its markings, but just one in a million in composition? My dear old Daddy called it fieldstone, but I am sure it is a sediment based stone. Bongo

What are the dimensions?

An abrader is a tool that was used to create a rough surface on the edge of a flint preform, so as to make it possible to remove exact flakes in the creation of a spear point. Normally, an adrader is held in the hand. It gets scarred up similar to the marks on your object. It is possible that it was used like a workbench to sharpen bone awls, or prepare platforms on the flint, like I described above.

Good luck finding out!
