Fossilized ammonite shell?

Where was it found ? Whithout knowing the finding location, its hard to tell what it is. My best guess would be a rock in a rock.

Are good signatures really that important ?

Montgomery County, PA which I’ve been told is not the expected geology for fossils. Just the appearance has me very curious - I’m very tempted to chisel away just to see the what’s creating the illusion!

Not seeing anything that says fossil.  I agree it is more likely a pebble within a conglomerate.

To me it looks too smooth to be an ammonite. They either have a regular ribbed surface or sutures (the weird repeating lines you'll see clearly on polished ammonite specimens).

I assumed those lighter brown sections would be the “sutures” you described?

I don´t see an ammonite illusion.
