A female Nanuqsaurus took a strange turn along the ancestral Colville River and finds herself feeling very small indeed among the towering giant plants of an ancient garden forgotten by time - a remnant of a warmer, wetter period of Alaska dominated by ferns, cycads, Bennettitales, dawn redwoods, and Ginkgoes, with interloping stands of flowering ginger plants as a reminder of the changing order of things.
Fossil footprints found in Denali National Park revealed that at least two species of pterosaur (ancient flying reptiles that were "cousins" to dinosaurs) roamed the north lands and flew the chilly skies of Cretaceous Alaska around 70 million years ago.
