The Arctic winter had arrived, blanketing the land in a thick layer of snow and ice. The cold winds howled through the barren landscape, chilling everything in its path. But in the far north, where the temperatures dropped to unbearable levels, a spectacular winter wonderland was formed. Most of the dinosaurs in the Arctic had already migrated to warmer areas, seeking shelter from the harsh conditions. But not all of them chose to leave. The largest and strongest dinosaurs, like the Pachyrhinosaurus, decided to tough it out.

These two-tonne herbivores were equipped with extravagantly-armored heads, giving them a fearsome appearance. Instead of a horn, they had a thick, massive lump of bone called a 'nasal boss', along with a smaller boss over their eyes. This armor served as protection against the elements and any potential predators. The Pachyrhinosaurus roamed the frozen tundra, seeking refuge in the forests that still provided some shelter. They stripped the last leaves and dormant trees, and rooted through ferns or fallen fruit to find sustenance. Even though their autumn rut was over, two less-dominant males still clashed heads, trying to establish which one was superior. But their battle was short-lived as an old bull Pachyrhinosaurus appeared on the scene. With a single Bellow, the two males were confronted and swiftly driven away. The old bull then proceeded to scratch his left flank on a nearby tree, revealing a raw, open wound on his right leg. Despite his old age and injuries, the old bull was still a formidable force, and one that few dared to challenge. The battling males barely had time to eat or rest as they were constantly on guard against any potential threats. As they moved through the frozen landscape, the herd left a trail of destruction in their wake. The trees were stripped bare, and the ground was trampled by their footsteps. But the Pachyrhinosaurus paid no mind to the damage they caused, since their survival was their top priority.
