A 9 km asteroid hit Mexico’s Yucatan Peninsula 66 million years ago, causing a mass extinction. A new study suggests that if it had hit elsewhere, the damage wouldn’t have been as catastrophic and dinosaurs may have survived. Only 13% of the Earth’s surface had the right composition for such an extinction. A roughly 5.6-mile […]
Seven US states have official state dinosaurs, chosen based on fossils found in those states. Colorado’s stegosaurus, Maryland’s astrodon, and Missouri’s Hypsibema missouriensis are among them. Other states have official snacks, toys, and sports. Every state in the United States has a list of official symbols representative of that state’s identity, and there are seven […]
Jurassic Park movies may have influenced polls showing 40% of Americans believe humans and dinosaurs coexisted. Only 54% of respondents in a 2015 poll knew cloning DNA from fossils isn’t feasible. Dinosaurs went extinct before humans appeared on Earth. Jurassic Park and its sequels — including 2015’s record-breaking Jurassic World — have had people in […]

The prevailing theory is that a 6-mile asteroid hit Earth, causing widespread destruction and killing off most land animals larger than a cat. The asteroid impact caused acid rain and killed marine creatures that depend on their […]
