 A Grand Rapids angler landed an unusual trophy when he reeled in a shark jawbone while fishing on the Mississippi River. Joe Piskall caught the jawbone near Grand Rapids over the weekend. He and his son Joey brought it to a DNR office where a fisheries biologist identified it as being from a sand tiger shark. That's a saltwater species that can survive in fresh water. Its origins remain a mystery. Joey Piskall says the jawbone will be cleaned up and hung on the wall.
