I found this many years ago in Maine. I feel like there is some signs of it being a tool or I could be completely
wrong. Would love to hear your opinions as to what it could be.
I would have to go along with quito unless a better photo showed me it was not. A lot of stone will wear down leaving a ring around them due to another mineral being in that stone. Welcome to T-net
Tough angle can you forward a profile pic of the top going down to the possible tip. Could by worn grooved axe but from what I see now would agree with others - natural. Close ups of the worn edges would be great as well. On the right path I most likely would have picked it up as well. Welcome to TNet!
