I found these in NE Colorado along a stream washout.

I don't think they are natural stone.  Are they man made pottery pieces?

Anybody find anything like these?

Normally in a stream context they would be rounded and eroded by other rocks and water action. The curves and edges being sharp would indicate man made and not natural. What do you mean by a 'stream washout' though?

You find shards of pottery at nearly every large archaeological site in history. Pottery shards almost define human civilisation, as they are so universal as containers. So these shards would be defined by the place they were found. What they do in archaeological excavations is fit these shards together like a jigsaw puzzle. The more you can find the better the idea of the object you would have.
If they were washed out of the side of a stream, then the exact site would be very important. They could have age, they could have been dropped ten years ago! Your best port of call would be a local museum, who would have knowledge of the area and similar finds.

They're not pottery; they're bone. Possibly the skull or pelvis of a cow or Bison, or a marine animal or reptile; maybe a turtle shell. They dont appear to be fossilised but I'd recommend taking them to your nearest museum and checking that out.

They are stone in hardness and texture. The reason I thought they were pottery is because of the thin layer surface texture and the makeup of the interior. The interior seems to be clay like. I know there seems to be bone texture on the edges but looks like sand up close.

The interior is typical of bone. Marine bone can be harder than terrestial animal bone.

I think they are bone also - some skull of a sheep or cow. In any case you would probably do better on an archeological website

Petrified bone? Definitely solid like stone.
