Asked July 5, 2018, 4:22 PM EDT

I found this while looking for river rocks in lake Huron and i found this. It looks like a tooth. But would like an expert opinion.

It looks like a fossilized Rugose coral to me. While the outside looks like a tooth, the interior structure does not resemble a tooth at all.
Here is a link to a Wikipedia article on Rugose corals
