Possible Native American tool or Artifact

Found this south of lordsburg New Mexico... there was a naitve American farm a long time ago just west of were it was found... its a rock, but look at the cuts in it.. looks like it was possibly a tool of some kind of tool, or was going to be...
This show the direction and distance from where the farm site was and where i found the rock... the left end is where the naitve american farm site is... the right end is where i found the rock...
Heres a photo of Dogs Head mountain peak, its where the naitve american farm site or area was...

 

Wonder if this is something @Taupou will know about.

 

if it was going to be a tool....it looks like it was likely discarded ...

 

I can't see it being used as a tool, but I'll tag @2manybooks

 

You would want to see some sign of alteration. Chipping, grinding something like that which would be different than other rocks in the area. I don't know if this information applies to the area you found this but you might look for similar information or contact the Archaeological Society/Agency in the area. There is a lot more info in the report.

I used to go out and hunt artifacts and still do have some of my artifact collection left. Looking at your piece I don't really see any indication that it was worked on. Pics are a little blurry so just going by what I can tell. I think you might just have a neat looking rock. I would definitely keep looking around that area though! Although in one of your pics I did see where one edge curved down and then goes straight. Maybe take a pic outside on that edge. Its possible they could have worked on that side then decided to toss it.

 

Not any sort of tool/artifact that I recognize.
It does not look like a type of stone that can be worked by flaking. If it were a sharpening stone, or a paint palette, I would expect it to have at least one totally flat surface, which does not appear to be the case.

 

Heres a better photo.. theres a bit of a flat surface.. it seems to have some kind of dotted like markings on it..

 

Heber, were you thinking of part of a (small) metate, maybe? Like this one?

That kind of looks like the rock... though looking at it i wonder if the rock i have was broken off from one of these.. it might have been a part of the back and the sides smoothed out over time...
