What does a 750-pound alligator eat? One Mississippi alligator will eat just about anything including a broken stone arrowhead and another prehistoric object. Shane Smith, owner of Red Antler Processing in Yazoo City, Mississippi, said he was examining contents of a 13-foot, 5-inch alligator that weighed 750 pounds and discovered the two unusual objects. "My best hypothesis is wherever he scooped up those other rocks, he got that (Native American) point," Smith said. "We joked about it and said I'm probably the only person on Earth to pull an arrowhead out of an alligator's stomach."
