In this long-awaited sequel

Kirk Johnson and Ray Troll are back on a road trip-driving, flying, and boating their way from Baja, California to northern Alaska in search of the fossil secrets of North America's Pacific coast.

They hunt for fossils, visit museums, meet scientists and paleonerds, and sleuth out untold stories of extinct worlds. As one of the oldest coasts on earth, the west coast is a rich ground for fossil discovery. Its wonders include extinct marine mammals, pygmy mammoths, oyster bears, immense ammonites, shark-bitten camels, polar dinosaurs, Alaskan palms, California walruses, and a lava-baked rhinoceros.

Join in for a fossil journey through deep time and discover how the west coast became the place it is today.
