I am guess that the two darker pieces you have were heat treated. I have cooked a lot of Texas rock and cooking it up turns the grainy rock into butter smooth like those two dark pieces. Just a guess on my part. I love that Texas rock.
I just put that in there for size lol......I am thinkin Mid archaic there abouts.Never found Paleo,but a fare bit of Early Arc....Early triangles,Nolans and the such.
Yep thats some charcoal..I use it to fill in etching I make on limestone and bone things I make...All Abo...I find limestone pieces and bone,then I use flint flakes to shape and etch.I could prolly find some pix if anyone would like to see some.

That last piece has some steep beveling on it is the reason I asked. There is a nice large shaft scraper and I see some other pieces that made me wonder. I would go back to that spot.
Yeah it rained on me today too. I was finding some good artifacts and I had to run back cause if the clay road got wet I wouldnt of gotten out. Ill get them next time!
