Found this one day while picking pine needles out of the landscape/river rock in my front yard. Kinda looks like a bug or maybe just a chip. What do you all think?

Not a bug. Not going to have a fossil in an intrusive rock. I'm not the greatest igneous petrologist, but looks to be an irregular agglomeration of hornblende crystals.
