What kind of fossil is this? Is this even a fossil?

My boyfriend works in northern Ontario (Canada) at a limestone rock quarry and found this while chipping a piece of rock. I am not sure if this is even a legitimite fossil and if so what kind it is and would love some feedback!

Welcome to TFF!

It looks like a piece of a orthocone/nautilus.

Not sure but it may also be a banded chert look alike.

Hi @ShanniElle!

 

Welcome to the forum!

 

I initially thought that your piece might be an orthoconic (straight-shelled) nautiloid - a type of extinct cephalopod - but after looking at your pictures more closely I'm not so sure...  I've found quite a few orthoconic nautiloids down here in the Toronto area, and from what I've noticed, the segments extend from top to bottom on each piece.  Your piece doesn't seem to have segmentation right to the "top".  The segments in your piece also seem to have different widths - that could just mean that your piece is a bit smushed, but I don't know...  I'm thinking it's something else, likely geologic like Rockwood has said...

 

Keep looking!!!

They really are an unusual fossil aren't they, I found a Gomphoceras ellipticum from the Elton beds over Wenlock limestone. I'd like to try and prep it further but not really sure how.
