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 […]
Lonely northern cliffs from which scientists have pulled the bones of Alaska dinosaurs also hold the fossilized remains of birds. Lauren Keller is studying the tiny specks of teeth and bones of birds that died more than 70 million years ago in what is now northern Alaska. Keller is a graduate student working with the […]
First record of theropods — dinosaurs that include birds and their closest non-avian dinosaur relatives A study led by scientists at The University of Texas at Austin is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of theropods […]
Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research published this month. The finding, published April 2 in the journal Geosciences, discusses the distribution of hadrosaurids and ceratopsids — the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago. The work […]
