Okay, I found this tooth in Wisconsin. It was on the shore of an island that was land 90 years ago. Can anyone tell me if this is a shark tooth. The closest I can tell is its a mako, but all history books say that would be impossible. Maybe its reptile or some kind of gar, or maybe a even a mammal...
Here is a video link.....and yes I'm a painter on break, hence the dirty hands lol.
