Is this a coral fossil?

[Jeaniegirl]

Hi Everyone!

I’m new to the forum and have been picking up some interesting fossils and stones over the last few weeks. It’s been really exciting identifying my finds with an app I’m trying out. However, this app can only recognize this stone as its mineral property-calcite. Maybe it’s nothing, but it seems to me that the grooves are unique. 
Opinions? 🤔

Location is key to identification.

Definitely NOT a coral, but it could be part of a bivalve.

Thank you for your opinion! I do most of my hiking around the creeks, streams and rivers of Central Indiana, so I can see how that is probable. I believe this one was found near Wildcat Creek in Lafayette.

Welcome to the forum. It's not calcite either. Calcite is clear, whitish, milky white, or yellowish. The white spots on it may be calcite.

 

Don't believe anything that the mineral or fossil ID apps tell you. They are at least 20 years away from being dependable. At this point in time they are about 15% believable.

 

Fragment of bivalve most probably. I agree with Tim.
