But this opens so many possibilities. For starters it means therizinosaurs probably returned to what would today be North America at the end of the Cretaceous. The track was found in Denali National Park, where the tracks of Albertosaurus, hadrosaurs and troodonts have been found as well. I wonder if any of these North American therizinosaurs made it to the south. Who knows! Maybe we'll find a Therizinosaur in Hell Creek one day!
PS- If this creature was living in Alaska, it probably had a thick feather/dino-fuzz coat. Interesting if we consider Beipiaosaurus from the early Cretaceous was also seemingly well adapted to cold climate. :>
