Sauropods avoided volatile tropics in Triassic

(Newser) - Scientists have long been baffled by a lack of Triassic period fossils from large, herbivorous dinosaurs known as sauropods near the equator. A new study offers some illumination: It suggests a hot, unpredictable climate and high carbon dioxide levels kept some of the world's first dinosaurs away—and may...

(Newser) - An explosion of volcanic activity 200 million years ago may have been responsible for the mass extinction that left dinosaurs with few competitors and allowed them to dominate the Earth for almost 150 million years. Researchers have discovered evidence of massive lava flows concurrent with elevated levels of CO2 in...
