An electric blue Parksosaurus warreni “dances” among a wide variety of flowering plants known from different locations across Alaska and Russia during the Cretaceous era. While we are most familiar with the Pleistocene-era Bering land bridge connecting North America and Eurasia, evidence of many shared fossil plant and animal species show Alaska also bridged the continents during the late Cretaceous. Plant fossils across the arctic point to a warm, dense forest that covered the northern extreme of both continents, brimming with many flowering plant species and a wide diversity of fauna.
