Ancient Dinosaur Tracks Uncover Alaska's Lush Environment
A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago. The findings by an international team of scientists led by paleontologist Anthony Fiorillo were published in the journal Geosciences, shedding light on the lush, wet environment of the mid-Cretaceous period and providing insights into the high-latitude ecosystem on a warmer Earth.
