Does this stone show signs of being worked?

[Rustic]

Hello friends, I'm a run of the mill detectorist with zero experience with Native American artifacts.

Yesterday while detecting a field by the river I started noticing many broken stones. Their location was strange,as the fields here abouts don't have stones usually, and there were interesting colored pieces, quartz pieces, and what appeared to be many fist sized river cobbles that had been fractured in various ways... anyway it made me curious.

I lugged some of these stones home to ask your opinion on the one that seems like a possible candidate for having been worked by Native Americans. What do you think?

I took pics from about every angle. Please feel free to chuckle at my wishful thinking if need be, lol.

Sorry, I don't see anything that says hands of man worked on the stone.

I would say natural too but I sure would have picked it up and looked twice. Keep Looking. It will happen.

I think that Isee what you are getting at, that edge looks worked... however, I believe that's a natural rock.

I don't believe so. Most percussion flaking or pressure flaking was done with much more "glassy" rock. At least in my neck of the woods. Like Obsidian, Jasper, some Agate. That second image along the bottom edge of it has some strange line to it... but I think they probably had better material to use for edged tools than river cobble.

I agree with the above- but that edge in the first pic, does look something like "an edge" and almost looks worn a bit.
