Arctic journal reports that the vertebra of a duck-billed hadrosaur from the cretaceous period found in the northern Canadian territory of Nunavut suggests that the giant herbivore made its home in the hostile northern region year-round. In fact, the bone found on Axel Heiberg Island is the northern most fossil find ever recorded.
Although the average Arctic temperature was fifteen degrees warmer than today, the hadrosaurs still had to contend with a complete absence of daylight for almost half the year. The relative cold and lack of a plant-life meant a tough life for the hardy duck-bill. Mostly they would have scavenged twigs, decaying wood and fungi to survive. And migration was impossible because the island on which the fossil was found was cut off from the rest of North America by two seas.
It seems the more we learn about dinosaurs in the fossil record the more surprising and extreme they become. You go dinosaurs!
