Native Stone Tool or Weapon?

[TJE]

Hello to all, bit of a newbie here. Great site here..and good people
I've some pics here of what I believe could be a native hammer/tool or even a possible warclub/weapon. It's just a bit smaller than a closed fist and has some good weight to it. I discovered it on the shoreline of Georgian Bay (across from Lake Huron on The Bruce Peninsula). Anyone have better knowledge than me (which isn't alot) in this area of finds.It would be much appreciated.
Thanks.

You have a grooved maul I think. I can't say for sure, but I am pretty sure. Nice find!!

Hey NC, thanks for the info. Any way I would be able to get it dated?
Thanks again.

It might be natural. I cant tell cause it is so blurry. If anything I would say a grinding stone but I cant see if there is any use wear on the flat side. You need better pictures almost all of these are fuzzy. Sorry

Take your pics outside and use the marco setting. You will get a great deal of a better pic
