Finds from the Trash pile, Can I get some answers or theories?

[blueracer]

One indians trash is another mans treasure. I figure the reason I cant find a complete tool is because Im picking through a garbage pile. I have some questions about some of the things I found.
1. one of these arrowheads is not like the other, but they were all found within feet of each other, on hard pan, along with all the other stuff. can they be from the same age? because one is very different.
2. what are the long skinny pieces? are they just flakes?
3. does anyone see anything that might be a tool in these pictures? notice one of the long skinny ones has a point on one end. It appears to be purposeful, is it a blade? I know some of them are just cores. Thanks.

I really enjoy finding the blade type of tools. Secondary flaking on the edges by chance? Looks more like you are in a camp site instead of a trash pit.

the long skinny ones are chipped along the edges and seem to be serrated. Im not sure does that happen over time or is that purposeful? The fourth long skinny one from the left seems to have a purposeful point added to it. also the middle rock in the second row under the arrowheads has chipping or flaking on the curved edge and is dome shaped like a clamshell but flat on the bottom. Do you see anything that you recognize as some sort of tool?

Are you in Florida?
Looks like you have a Bolen and two Newnan bases.
If your on hard pan.. everything above it can wind up there.
Bolen is early archaic and Newnan is middle archaic.
The pink one and Mabey even the Bolen look like agatized coral.
The thick patina on the older Bolen is hiding the actual material.
Try going a little further down in the hard pan.. there might be a paleo piece hiding in there.

gatorboy, I meant to be more elaborate with that question but I must have been distracted. You already helped me determine the ages of two of them and that the white one is older. Was it common for them to find older arrowheads and re-use them? I was wondering if since they were in the same area if they had been placed there around the same time, but theres probably no way to tell. especially if the same area was used over and over again and like you said on hard pan. I think the pink one is agatized coral, the brown one seems to have slivers of shell fragments and the white one underneath has strange markings but doesn't seem to show coral polyps seems to I am suspicious about when the hardpan formed it may be more modern. it is only about an inch thick and there seems to be nothing underneath and The area was farmland

The patina gives away the fact that the Bolen was in the ground longer...since you have examples of both types of material to compare to from the same soil.

Those skinny pieces look like waste from knapping that some of them got utilized for perforators or gravers.
In the group photo to the top right looks like what could be two scrapers with graver spurs.

It would make sense that if they found an all ready made point they would use it, kinda like us if we found a old pocket knife wouldn't you use. JMO some points got mixed in at different times.
