Corn worked with a Cornell graduate student, Stacy Farina, and a University of Washington biologist, Adam Summers. Corn had been taking Summers' class at UW's Friday Harbor Laboratories, she says, when Summers asked, "Hey, does anybody want to glue shark teeth to a saw?" Corn said yes. Among her duties was defrosting the jaw of sixgill shark that had washed up in Friday Harbor two years ago, to collect the teeth. "It was a big shark," she says. "Those jaws were magnificent."
