Not sure what it is? Possible coral? Indiana

[JoGeb4]

I found this while I was on a hike and I took my kids to the creek near the trail. It looks like there’s some sort of crystal growing in a couple of holes too. I checked some stuff out so I’m not sure if it’s solicified coral or what. It’s pretty heavy and about the size of a baseball. These photos are side and top photos.

Nice. I would agree it's a tabulate coral fossil. Scroll down the page a little at the link below to see similar examples:

I'm next door in IL and we find lots of coral fossils in the glacial till. Gary
