Illustrated upper-middle-grade fiction of year in the life of Arctic dinosaurs: migration, predators, earthquakes, river breakups, aurora borealis, snow, and starvation. The story is nested in non-fiction. Factual information is provided.

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.

In 1961, while mapping rock exposures along the Colville River in Alaska, an oil company geologist would unknowingly find the evidence for a startling discovery. Long before the North Slope of Alaska was being exploited for its petroleum resources it was a place where dinosaurs roamed. Dinosaurs under the Aurora immerses readers in the challenges, stark beauty, and hard-earned rewards of conducting paleontological field work in the Arctic. Roland A. Gangloff recounts the significant discoveries of field and museum research on Arctic dinosaurs, most notably of the last 25 years when the remarkable record of dinosaurs from Alaska was compiled. This research has changed the way we think about dinosaurs and their world. Examining long-standing controversies, such as the end-Cretaceous extinction of dinosaurs and whether dinosaurs were residents or just seasonal visitors to polar latitudes, Gangloff takes readers on a delightful and instructive journey into the world of paleontology as it is conducted in the land under the aurora.

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.

“In the land where caribou now roam, there once lived strange and amazing creatures…” Discover Alaska's dinosaurs when you travel back through prehistoric time in Thunderfeet. Take a trip through 70 million years of history from the day of the dinosaurs to the migration of North America's animals across the Bering Land Bridge. Ages 5 and up. Includes a glossary for curious kids with more information about dinosaurs and other prehistoric critters. Thunderfeet is dedicated to all of Alaska’s animals. We hope the Last Frontier will stay a wild place.

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.
