Dinosaurs Under the Aurora
Publication Year: 2012
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.

To the hundreds of volunteers, teachers, and students that gave their time, sweat, and blood to unearth the story of Alaska’s Arctic dinosaurs, I am eternally thankful. Over my eighteen years of work in Alaska, I benefited greatly from the help and counsel of a host of colleagues. Some of the contributions of a number...
1. The Arctic Setting
Download PDF (1.0 MB)
The Arctic coastal plain is crisscrossed by a host of meandering rivers that drain the northern slope of the rugged ancestral Brooks Range to the south. The rivers are pregnant with organic-rich sediment and rush headlong to the northern sea, being fed by melting snowfields and the common cloudbursts that sweep in from the Western...

If you have seen the icon for the Sinclair Oil Company, a silhouette of a four-legged long-neck dinosaur, then you may have concluded that petroleum and dinosaurs go hand in hand. The misconception that petroleum is derived from dinosaurs is still quite prevalent even among those who are not familiar with the Sinclair symbol...

One can make a case that field research anywhere presents unique challenges. However, having done geologic fieldwork in environments as diverse as the rainforests of southern Mexico and the deserts of California and Nevada, I can say that I find the Arctic of Alaska to be the most challenging of all. Perhaps it is the condensed...

Over 3,000 miles (4,800 kilometers) of rugged mountains and high plains separate Alaska’s North Slope and Dallas, Texas, today. Most people would not think of Texas and Alaska as being close in any way. But there is quite a history that brings Alaska and Texas much closer than their current geography would ever suggest. In terms of “deep time,”...

North America and the western Arctic as experienced by dinosaurs and their kin were much different places than today. Today we find the planet dominated by large continents with interiors that are relatively far removed from the ocean margins. The oceans are now at what is called a low stand, because significant amounts...

The record of Cretaceous age dinosaur trackways and their common association with ocean shorelines has been steadily accumulating since the 1940s.1 One of the most impressive and best-known records can be found in central Texas, an area that occupied the southern end of the great Western Interior Seaway. The Early Cretaceous...
