Hello everyone, Please help me identify if this is a possible plant or mineral.  First time posting, thank you for your help.

Nice photos, @Helen’s rocks. If you could post one photo of side one with size around 3mb so we can zoom in, it would really help. So far these look like possible trace fossils.

Looks Dendritic to me.

Agree with Caldigger, looks mineral.

@Helen’s rocks. Unfortunately I was unable to view your last photo and saw this instead:

Were others able to view it?

 

I did notice some circular patterns in your first photo. @caldigger I'm curious, is that normal for dendritic growth?

To me, it looks like that it has some relief. My gut feeling is, that this is a fracture surface with a thin, partial mineral coating. I think, there is a special name for such features on a fracture surface. Plume structure?? Hackle surface?? But I can be totaly wrong, of course...

That's how Dendrites form. Manganese will seep into minute fissures in the rock and spread in fracture directions.

A lateral view of the specimen is needed.
I see voids in the exposed lateral view, but the picture is too blurry to make a more precise idea. :)
