Does this specimen appear to "be" a fossil?

I found this on the edge of a very slick, clay seeming, river bed, almost like a turfed out bed -- like it was rubber. It gave the river a very clear floor, down from a few beautiful babbling brook type areas. The river bed that was almost completely barefoot safe, had small holes embedded in the element. Very beautiful it was almost like it was manmade but it wasn't. Because the material, if pressed very hard or if my heel fell into one of the small holes it would have caved in. It was a beautiful work of whatever it was. Anyway I found this in a rock that I had seen multiple splits in and the rock is so fragile and has tiny pieces of sentiment in it almost like I've seen many fossils before. It's very light. Just curious if someone could identify what it is. Or what that material in the river is? It almost looked like lava had hardened there... But I assume it would have been harder rock for sure. =) Thank you.

I’m thinking it is a piece of tile but I could be wrong.

 

per the rules of the Fossil ID page, please indicate where this was found

I agree. It appears man-made to me.
