Uninitiated with unknown fossil

[SueBSouth]

I have had this specimen for 30 or more years in a disorganized collection of rocks, shells and fossils. I am not sure if I found this in 1983 on the coast of Oregon, near Newport (where I also found some Pelecypods), or if it was in 1988 in a dry creek bed in DeRuyter, NY (south of Cazenovia, which is South and East of Syracuse). 

I thoroughly bummed that in my last and I hope final move this piece cracked and when I went to photograph it last night, it broke! Oh, and yeah, that is a golf ball I am using to show size, I couldn't find a single coin around! Photo #1 oblique angle, #2 birds eye view. 

Any ID help welcomed.

Hello, and Welcome to the Forum.  

 

It looks to me like this is a piece of a Rugose or "Horn" Coral.

So probably found in the NY location.

 

Can you take a picture or two showing the inside of the break?

It might go further towards ID'ing the specimen.

Regards,

Looks like a collapsed Ammonite to me.

Here are some shots of the inside of the break. Thank you for this!

same photo inserted twice by mistake

That last photo looks like the whorl of the internal cast of a gastropod.

I just googled both ammonites and the horn coral, and I found this which makes me put my money on the horn coral!

It is a coral. The inside of the break reveals the internal structure of a horn coral.
