- 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 Teeth (FaceliftDentistry.com)
"Fossilized teeth give scientists clues about how dinosaurs ate. Some front teeth are designed to bite and tear off meat. These teeth are called incisors, and they have sharp points. Other teeth in the back are used to grind food before swallowing. These teeth are called molars. When scientists find flat front teeth in a dinosaur skull fossil, they guess that the dinosaur ate plants." 03-17
