Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.

A team of scientists and researchers endured incredible hardships to reach a site many would rather avoid - the Alaskan wilderness - and in the process, uncovered unfossilized dinosaur bones. The implications are enormous, for how can dinosaurs be 65 million years old if their bones are still unfossilized?Join the team and thrill at the photographs and tales of danger, as The Great Alaskan Dinosaur Adventure drops a bombshell on the scientific community.

The Liscomb Bonebed (LBB), found in the early Maastrichtian Prince Creek Formation of northern Alaska, is the single most productive site for the Arctic dinosaurs in either hemisphere. From the LBB, thousands of bones representing at least hundreds of individuals of a saurolophine hadrosaur have been collected, but they have not been previously described and their taxonomic status remains unresolved. In part, this stems from the fact that most material comes from individuals approximately one-half to onefourth of adult size. Another long-standing question concerns whether dinosaurs in the Prince Creek Formation overwintered in the paleo-Arctic or migrated elsewhere (presumably south) to escape prolonged darkness and cold. Here, I attempt to determine the taxonomic status of the LBB hadrosaurs using three semi-independent methods: 1) geometric morphometric analysis; 2) comparative morphological analysis; and 3) cladistic analysis. An important component of this work also includes an ontogenetic study of the growth patterns of the genus Edmontosaurus, to which this material has been previously referred, in order to better understand ontogenetic variation within the Alaskan taxon. My results indicate the Alaskan taxon is a new species of the widespread genus Edmontosaurus. For the first time, the Alaskan taxon is described in detail, making it the best known polar dinosaur to date. My cladistic analysis suggests a possible biogeographic scenario in which the common ancestor of Edmontosaurus and Shantungosaurus originated in eastern Eurasia and then dispersed by the Campanian to North America via a land corridor in the area of present day Alaska. Finally, I used a novel method involving strontium isotope geochemistry to test the migration hypothesis of the new species of Alaskan Edmontosaurus. I measured strontium in tooth enamel of Edmontosaurus and a putative non-migratory species (Troodon) using LA-MC-ICP-MS. My results suggest diagenesis had not significantly altered the signal and that Alaskan Edmontosaurus likely did not migrate during approximately the last four months of life. My results lend further support for the existence of a distinct, early Maastrichtian polar dinosaur fauna known as the Paanaqtat Province.

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.
