Nanuqsaurus, standing in the background, and pachyrhinosaurus, skull in the foreground, were among the dinosaur species included in a new study led by scientists at the University of Alaska Fairbanks and the University of Reading that calls into question Bergmann’s rule.
The dataset included the northernmost dinosaurs known to scientists, those in Alaska’s Prince Creek Formation. They experienced freezing temperatures and snowfall. Despite this, the researchers found no notable increase in body size for any of the Arctic dinosaurs. The researchers say the study is a good example of how scientists can and should use the fossil record to test current-day scientific rules and hypotheses.
Scientific rules should apply to fossil organisms in the same way they do modern organisms, said Pat Druckenmiller, director of the University of Alaska Museum of the North and one of the co-authors of the paper.
