(Inside Science) -- The age of dinosaurs may have ended in springtime in Mexico, which may help explain the pattern of extinctions that resulted, a controversial new study now claims. After dominating the planet for roughly 135 million years, the dinosaurs' reign ended about 66 million years ago, with the killing blow most likely dealt by an asteroid roughly 6 miles (10 kilometers) wide. The result was a crater more than 110 miles (180 km) across, near what is now the town of Chicxulub in Mexico's Yucatán Peninsula.
