In the 1950s, people accidentally discovered the remains of dinosaurs in the cold polar regions for the first time
Patrick Druckenmiller of the University of Alaska’s Northern Museum said: “These are the dinosaurs known to inhabit the northernmost part of the earth
Druckenmiller mentioned that previous studies have provided some evidence that one or two unknown dinosaurs are capable of nesting near or within the Arctic and Antarctic Circles, but this research is the first clear evidence that dinosaurs nest in high latitudes
extreme Druckenmiller and Gregory Erickson, co-author of the paper from Florida State University, are working on a long-term project to document the ancient Arctic ecosystem preserved in the Prince Creek formation in northern Alaska, including dinosaurs, mammals and other vertebrates
"The field trip season in the Arctic is very short and it is very difficult to get there-airplanes and boats are required
After about 10 years of hard work, with the help of many students, researchers have discovered hundreds of small dinosaur bones, including small teeth of individuals that are still in dinosaur eggs or newly hatched
" It is amazing to find dinosaurs in such extreme latitudes and environments, and it is amazing to find that most (if not all) of these species also reproduce in the Arctic
extreme These findings further prove that dinosaurs not only live in extremely high latitudes, but are likely to live there all year round
"Living in the Arctic throughout the year provides a natural test for the physiology of dinosaurs
Erickson said that now there are new questions about how dinosaurs survived the Arctic winter
