Dr. Pat Druckenmiller is currently involved in a large collaborative project with the University of Oslo Natural History Museum in Oslo to investigate a prolific new site of Jurassic-aged marine reptiles from the high Arctic archipelago of Svalbard.

Arctic Dinosaurs of Alaska

The UA Museum hosts the largest collection of Arctic dinosaurs in the world. In collaboration with Dr. Greg Erickson at the Florida State University, we seek to better understand dinosaurs that lived in Arctic Alaska during the Late Cretaceous, approximately 69 million years ago. This work is sponsored by funding from the National Science Foundation.

Several exciting discoveries of marine reptiles have been made in Alaska. Most recently a world class specimen of a thalattosaur, a small Triassic marine reptile, was made in southeast Alaska. Other exciting finds currently under study include a large ichthyosaur with gut contents from the foothills of the Brooks Range, a new Middle Jurassic ichthyosaur from the Talkeetna Mountains, and a small, rare ichthyosaur from southeast Alaska.

In 2010, a team of Alaskan scientists, lead by the UA Museum, rediscovered a dinosaur trackway found 35 years earlier near Chignik, Alaska. The tracks were found in the Upper Jurassic Naknek Formation and constitute the oldest record of dinosaurs found in the state. We are currently investigating other possible occurrences of dinosaurs in the formation on the Alaska Peninsula/Becharof National Wildlife Refuges.

University of Alaska Museum of the North researchers have found a major new site for dinosaur fossils in Alaska along the Yukon River.
A recent trip netted about 2,000 pounds of dinosaur footprints for the museum’s collection, according to earth sciences curator Pat Druckenmiller»“There aren’t many places left in the world where paleontologists can just go out and find thousands of dinosaur footprints. This is the kind of discovery you would have expected in the Lower 48 a hundred years ago.”
In July 2013, researchers set off in boats for a 500-mile journey down the Tanana and Yukon rivers. Co-discoverer Kevin May, operations manager at the UA Museum of the North, says the goal was to explore as many beaches as possible for evidence of dinosaurs. “Based on what we know about the geology along the Yukon River, the rocks exposed downriver from Ruby suggested they might be a good place to find dinosaurs”.
They found much more than they expected: dinosaur footprints big and small, from both meat- and plant-eaters.
“We found a great diversity of dinosaur types,” Druckenmiller said, “evidence of an extinct ecosystem we never knew existed.”
