Stanford scientists have found that chronically low levels of oxygen throughout the oceans hampered the recovery of life after the Permian-Triassic extinction, the most catastrophic die-off in our planet’s history. Also known as the “Great Dying,” global ecosystems collapsed as some 90 percent of species perished in this extinction event 250 million years ago. The new findings, published this week […]

Modern-day mousetraps wouldn’t stand a chance against the supersize rodents that roamed South America about 2 million years ago, National Geographic reports. A giant ancestor of the guinea pig, Josephoartigasia monesi weighed more than 2,000 pounds and stood 5 feet tall, roughly the size of a modern buffalo. Because the critter also sported foot-long buckteeth, University of York scientists wanted […]
