I thought I found a really thin bone pin at first. I'm pretty sure this had an eyelet at one time. This is a first for me. Can't belive this was never snapped in half.
The only thing I'm sure of at this point is that the concave portion that is visible didn't break that way. The ends that would have been broken if it were a needle aren't jagged but I'm not sure if that's from wear. The " notch" or hole" whichever the case was drilled from what I see under magnification.
The lenght and diameter seem to match other bone needles recovered from archaic contexts in Florida. I don't think it would be stout enough to handle Hafted impact. Unless used as a blow dart which isn't talked about much but has been written in some Florida archaeological reports I have read. I'm leaning towards needle.
