What the heck is this rock?

I found a weird little rock while hiking in southwestern Wisconsin. I'm trying to figure out if it's man-made or a fossil, and what it could have been a part of.

I found this little rock on a trail in Blue Mounds State Park in Wisconsin. Here's the top
, and side
. The trail was pretty rustic...there were some timbers in spots on the trail to prevent it from washing out during a heavy rain, but there was no cement or other material near the trail that looked anything like this. I think it might be man-made because the holes are so uniform, but members of my family thought it looked like it might be a natural rock or a fossil.
Does anyone have any idea what it could have been a piece of, if it was man-made? Or what it could be a fossil of, if it's a fossil? It's been driving me nuts.
