Does this stone contain a fossil?

[Roadkill]

Hello all, I apologies in advance as I do not have any experience with geology (although I have family members who are geologists), nor I have I ever been fossil hunting before. I am interested in paleobiology but I’m only an art student so forgive me. Some context;

I live in northwestern British Columbia on the intermontane belt. I was wading in the river near my town and came across this stone under the water. I was wondering if this is in fact just a stone or if it could be something more? The fossils I know to have been found in my area are mostly invertebrates like ammonites and bivalves as well as a lot of plant matter. This looked very similar to a fossilized lobster my friend has and that got me curious.

 

 *First two images are of what I found, last one is the type of fossil I’m used to in my area.

Looks like some sort of breccia.

Are these black inclusions harder then the matrix?

Can you scratch the black inclusions with a needle?

And you are having some nice plant fossils around you .

The inclusions can be scratched with a needle but don’t seem to be significantly softer than the matrix.

Looked into it after reading your comment and that seems right.
