Rock with Two Identical Holes

[fldwlkr]

Road trip today to a creek I enjoy playing in.

Lots of gravel, deer, and a few pieces of flint. I picked up this rock because of the two identical holes in it.

It has a color change around the holes and a slight perpendicular dent between them one side.


It's pretty beat up from the creek but I'm thinking man made. Any opinions and input would be most appreciated.
Good Luck out there, fldwlkr (creekwalker today)

I don't see what else it could be. It has to be man made

Interesting piece. Is it a sedimentary rock? Are those little round fossils in it? At first glance it looks man made to me. Just a though, it looks like rust stains around the two holes. Could it have been a make shift shim of some kind? Two holes drilled into it, two bolts with washers put into holes? Would explain the round orange stains. Again, just thinking out loud. Lets see what others think.

I think the staining around both holes may be very good indicators there were inclusions of some kind in those holes.

Wondering do the holes have any drilling or are they smooth inside.sometimes you will see like lines or drill turns.

After further review, I am less inclined to go with man made. The few pieces I have that are drilled have conical holes and are drilled from both sides. These holes have little or no taper. It is made of sandstone and the area is sick with banded slate, so why use sandstone? Not sure how it came to be, maybe Crinoid stacks.
I'm gonna hang on to it for awhile just in case, fldwlkr

...conical holes, or at least one opening larger than the flip side... that would be Native drilled. FWIW I once found some broken up slate shingles that had holes and for about 5 minues I thought I found an ancient artifact, until I found a bunch more rectangular ones a few yards away in a pile

LOL

Just a thought. It could be limestone that has had two crinoid fossils errode out of it.
