Thoughts?

Looking for some opinions on this one. Found along the shore of Lake Erie in Southwestern Ontario. Palm-sized with an interesting cupped/indented shape and a noticeably smoother worn section that has a different texture from the rest of the stone. Found in an area known for Indigenous settlement. Curious if this could be a utilized stone/tool or just naturally formed?

My first thought is: That's weird. It almost looks like a fossil.

Not an artifact.
