Discarded biface. I see a hairline crack across the tip. Also, that area just above the indentation is a fatal flaw. I have buckets of bifaces I found at flint quarries and every one has some flaw that made them reject it. If it was a good one, they didn't leave it for me to find. Gary
I will take more pictures tonight of the reverse side.. Thanks for the comments all..A guy a few years ago told me he thought it may be a flaked axe..Its quite large I think over 7"
