Eumeralla Formation, Australia, 120 MYA

Take a trip to the Early Cretaceous of Australia, a time when the land down under and the Antarctic are joined as one. Here they are connected by a vast rift valley containing many rivers, floodplains, and polar forests. One of the many residents of this lost world is a female Leaellynasaura named Lea. Every day in these dark woods, she makes a voyage in search of food. However, such a trek is not without its perils. Between the apex predator Australovenator and the ancient carnivorous amphibian Koolasuchus, these runs are far from a simple walk through the park. And if she's not careful, this trip may be her last.
