Angler hooks sand tiger shark jaw bone from Mississippi River 17 May 17

An angler hooked onto a jaw bone of a sand tiger shark in the Mississippi River over the weekend’s opener. The fisherman brought the jawbone to the Department of Natural Resources Office Monday morning to find out what it was he reeled in. Fisheries biologists at the DNR identified the bones as that of a sand tiger shark, a salt water species that could not possibly survive in Minnesota waters. The jawbone was pulled from the Mississippi River near Grand Rapids and measured 10 inches across. The bones were returned to the fisherman.
