Asteroid Wasn't the Only Cause of the Death of Dinosaurs (Time.com) "There's never a good time to get clobbered by an asteroid — something the dinosaurs discovered in the worst way possible. It was 65.5 million years ago that an asteroid measuring 6 mi. (10 km) across, slammed into the Earth just off the coast of the Yucatan Peninsula, blasting out a 110 mi. (180 km) crater and sending out a cloud of globe-girdling debris that cooled and darkened the world. That spelled doom for species that had come to like things bright and warm. Before long (in geological terms, at least) the dinos were gone and the mammals arose." "That's how the story has long been told and it's still the most-widely accepted theory. Now, however, a study led by scientists at the American Museum of Natural History in New York City and published in Nature Communications suggests that the asteroid may not have affected all dinosaur species equally." 05-12 Dinosaur Heart Found (Time.com) Provides evidence that dinosaurs were warm blooded, like birds and mammals.
