THE MESSAGE BOARD POINT CHATTER IS NOW CLOSED TO ALL NEW POSTS.
From what I see, it does look Paleo. Collateral flaking and design are the sure signs.
No guestimates from me, they all look 'old' One snippet of info we just picked up at the Paleo Gault site tour....Paleo peoples were VERY inclined to sharpen their points right down to a nub, very economically minded. That third pic down point was probably 8 inches long before you found it
The last pic does appear to be a Goldrinia & the shorter point is pretty rough to be a Plainview but if the base is ground, then it's one.
