Can't help ya with the period Chef - but They look great. I particularly like the point on the lower left. If you get a chance I'd really like to see the reverse side. Do you happen to know the lithic material it's made from. Thanks for sharing them. ...Chuck

What part of South Texas? There are some pretty significant shifts in the types of points found in the San Antonio (South Texas for some people) or if you are down in McAllen or Laredo.

Looks like you got a smattering of periods. Late Archaic for the most part.
I see a Friday and a Covington possibly.
Not sure of upper right two and bottom right second in. Looks almost like a Mahaffey, can't see the detail. They could be early paleo if so.
Cool finds anyway. Lone Star.

Welcome Chef, some might be scrapers, but can't tell without seeing the opposite side
