In the coldest months, when the chilling winds sweep through the far west of North America, turning the landscape into a frozen wonderland, a spectacular woodland emerges. The mighty trees, once lush with leaves, now stand bare and covered in a glistening layer of frost. Not all creatures choose to leave or seek shelter during this harsh season. Some dinosaurs, particularly the largest ones, possess the strength and resilience to tough it out. In these alpine forests, where the air is frigid and the ground covered in a thick blanket of snow, there are other giant predators that roam. But, in this frozen land, these predators have no rivals. Tyrannosaurs. From the smallest members of their species to those as long and large as a school bus, these creatures possess a variety of incredible features. Their enormous size, combined with their impressive speed, makes them a formidable force. With binocular vision, they can spot their prey from a distance, allowing them to plan their attacks strategically. A keen sense of smell acts as their guiding compass, leading them to their next meal. Additionally, the cushioned pads on their feet dampen their footsteps, rendering their approach almost silent to the ears of their unsuspecting prey. Yet, their most striking feature is their powerful jaws.

In the heart of Horseshoe Canyon, where the wind whistles through the ancient cliffs, Woodlands started to thicken. With food becoming scarce, Pachyrhinosaurs struggle to rebuild their strength. Injuries take longer to heal, leaving them vulnerable and exposed. To make matters worse, they must constantly be on the lookout for the most formidable predator in Canada – the Albertosaurus. This king of the frozen lands is slightly smaller than the mighty Tarbosaurus of Mongolia, but still large and powerful enough to bring down even the largest of ornithopods and ceratopsians. This 26-year-old female Albertosaurus has traveled more than 500 kilometers from the Rocky Mountains to establish a new territory for her growing family.
