I don't think that old on those. It looks like you have Darl projectile points there.They are a transitional point type they may be late archaic at the oldest. The two "scrapers" look like Darl performs. All 2500-1000 BP.
Here are some Darl period sites in Texas. Judging by your previous post and your avatar pic...if these all came from that large midden complex it was occupied for a very long time.
Did you start a new hole when you found those? I'm guessing they were shallower than the one in your avatar. You will probably be hunting that site for a long time. You will most likely have an entire collection from that site. This website will help you alot and also help you put together the story of that site. www.texasbeyondhistory.net
