A couple from my "maybe" pile

[EricTheCat]

I keep looking and re-looking at a couple pieces from my "maybe" pile. I wondered if I could get some opinions. These came from my favorite local fields.
What do you think, are these the work of nature, incidental work of plows or the intentional work of man to sharpen these edges? It seems like these could be utilized flakes but I wouldn't put them with my for-sure pile without another opinion.

Seriously sorry if I am just adding to more geofacts posted here. If Tejaas (or anyone for that matter) feels like posting a cartoon response I have it coming!

This first one is oolitic chert I think. It has chips along both sides of one edge that is somewhat sharp.










This second one looks like a piece of jasper. Kind of looks sharpened on one side along the edge, other side left alone (in the last pic, the right side is the side that seems sharpened from the opposite side).








Happy hunting,
Eric

I'll be the first to say I'm not seeing enough about it to say it's from the hand of man. The flaking was done by other forces such as a plow as you mentions or other natural elements, imo. I can see why it caught your eye, as it would have mine also.

They could be utilized flakes. Looks like the flaking is predominantly on just one edge.

Plow damage? Highly doubtful.

From what I see the first one is just natural, the chips could have come from moving in a creek or river. The second one looks like a flake tool that got smaller chips in the sharp edge from rolling in a creek. JMO

Looks like pieces to me. I really not see anything whole. Next to last one looks interesting.

Thanks everyone. Though they were not found near water I live on a big glacial deposit so anything could have happened in the history of any rock I find around here. That keeps it interesting.

If it was natural chipping on about any piece, it would be pretty evenly distributed on all the edges. When you find worked edges, and unworked edges on the same piece, i would lean towards un-natural.
