How do you name a new dinosaur species? Look for something weird about it. Researchers announced the discovery of a new species from fossils overlooked for more than a decade.
■Class discussion: The video points out that "paleontologists previously thought long-necked dinosaurs died out after the Jurassic period. But recent finds, including Thunder Thighs, show sauropods kept kicking for another 50 million years." It's interesting how little we know for sure about our own planet and its development. Do you think we know more about outer space than we do about the earth?
