Wow, guess it did post. Good.
Your NOTTOWAY is the oldest point in the group, some say 10,300 years old, others say more like 9,500, but nobody would say less than 8,000 years old. There is good evidence for all of these dates, save for the 8,000 years old date. It's an old point-type, most of them were probably made from about 10,000 - 9,000 years ago.
Your ADENA is the youngest point in the group, it's also the most famous, the ADENA CULTURE is well documented, it wasn't that long ago, 2,000 -3,000 years. Pottery, fabrics, status symbols, the whole bit.
One of your points, the HALIFAX, is absolutely diagnostic of the
Late Archaic as it was in the eastern part of Virginia, most of them were made from a milky-white quartzite, yours is of a different material. There must be a source of this quartzite somewhere in east VA.
All of your points have seen a fair amount of use, some more than others. Your NOTTOWAY is the most obvious example. It was a knife for sure, see how it's been re-sharpened on the one side, to the extent that the shoulder has been removed? If there would have been another re-sharpening episode the other shoulder would be removed, and after that got dulled, it would have probably been re-worked into a drill-point. It was not used as a projectile point.
Notice your BIG SANDY (?), it too has been considerably reduced by re-sharpening, but symmetrically so, it's not lopsided. It was probably more projectile point, than knife blade.
Your LAMOKA (?) has also been considerably reduced, see how big the base is relative to the point size? That's a dead give-away that a point, any point, has been re-sharpened. As LAMOKA's go, yours has more pronounced basal features than most, most of them don't have such well defined features.
All in all, you have a very representative group of what was circulating in the East Central U.S.A., during the whole of the Archaic, particularly in or around Virginia.
