Cleo is writing a research paper about why the dinosaurs died out. She is considering four pieces of evidence. Examine each piece of evidence, and then decide which two would be best to include in her paper. Select the two correct answers. Modern birds are the closest living link to dinosaurs. That's because they share a common ancestor—the theropod. These were meat-eating dinosaurs. And they lived over 201 million years ago. According to National Geographic, lava flows in India sent dangerous chemicals into the air 66 million years ago. These chemicals were strong enough to kill many living creatures. Some scientists believe dinosaurs died out after a meteor strike. Evidence of a huge meteor crash was found in Mexico in 2016. And the crash happened around the same time dinosaurs went extinct. Dinosaurs are a group of reptiles that lived millions of years ago. The word dinosaur was first used by a naturalist named Sir Richard Owen.
