They're building a new highway and I found this where they had just dug up.

Could this be a fossil or just an interesting stone created by nature.

Hopefully you don't mind helping.

Given the rectangular shape of the inclusions, I would call this a "porphyritic" rock, wherein larger crystals have formed within a rock matrix with smaller crystals.

Debivort is right; it is a porphyritic rock. Probably feldspar crystals in a fine grained igneous rock that is worn down in a river.

 

It needs to be moved out of the fossil ID section.

My goal is to leave no stone or fossil unturned.   

See my Arizona Paleontology Guide    link  The best single resource for Arizona paleontology anywhere.

Very nice "keeper" example of a porphyritic rock.

Fossil hunting is easy -- they don't run away when you shoot at them!
