Cretaceous dinosaurs are recorded for the first time from southwestern Alaska by a series of three tracks found in Aniakchak National Monument. This trackway is the Upper Cretaceous (Campanian-Maastrichtian) Chignik Formation, a cyclic sequence of marine to non-marine clastic sedimentary rocks. The nearest coeval locality is approximately 1500 km northeast of this site, along a widespread Cretaceous Arctic terrestrial ecosystem taht supported significant numbers of large-bodied herbivores.
