Another Fossil ID

[moodorf]

I found this today. 

 

 

I think it's a really weathered tabulate coral fossil, but what I'm curious about is, I've never found one so weathered that the top of the tabulae are not visible anymore/gone.  

the fossil in the back is the most weathered coral fossil I've found thus far, and even that one has the open ends of the tabula still intact/identifiable.

 

Also weird is, that brown-ish part of the rock has something sparkling in it. like, little lines? It's weird, I've never seen lines on a rock quite like this. I'm assuming the brown is iron oxide? I've never seen that and quartz/mica/whatever on the same rock. 

 

 I'm probably using the wrong terminology for all this. Forgive my noobness.

 

I know this is a tough ID, and might not be possible, but I'm open on ideas. It might not even be a fossil at all, although tabulate corals come in a variety of shapes right ? hmmm.

I have to disagree. I'd call it a stromatoporoid. It's going to be tough to come up with definitive prof though I'm afraid. 

I usually call it a "personal" identification. Pier review welcome, but confirmation not necessary.

Top images look like slickenlines, often found on surfaces of faults. So, inorganic in my opinion.

The very top does. It might be interesting to see a polished facet across the other surface though.

Western NY, tends to look very horizontal for serious faults I think ?
