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 […]

An excavation site in North Dakota sheds new light on what happened when a giant meteorite struck planet Earth, 66 million years ago. On that day, violent ground shaking first raised giant waves in the waters of an ancient inland sea. Then tiny beads began to fall, created from molten rock cooling at the […]
During the late Cretaceous period, more than 65 million years ago, hundreds of different species of birds flitted around the dinosaurs and through the forests as abundantly as they flit about our woods and fields today. But after the cataclysm that wiped out most of the dinosaurs, only one group of birds remained: the ancestors […]
