Resurrecting the Shark - A Scientific Obsession and the Mavericks Who Solved the Mystery of a 270-Million-Year-Old Fossi

"In 1993 Alaskan artist and paleo-fish enthusiast, Ray Troll, stumbled upon the weirdest fossil he had ever seen in a museum -- a platter-sized spiral of tightly wound shark teeth, from the Helicoprion, a mysterious monster from deep time. In 2010 the undergraduate student, Jesse Pruitt, became seriously smitten with a Helicoprion fossil in a museum basement in Idaho. Together, they researched and were able, with others, to reanimate this awe-inspiring beast."--From jacket flap.
