Why dinosaurs matter (also: Rolf fact-checks the dino book he wrote at age 7)

“Common sense is a very poor guide to understanding the universe. Science is kind of the opposite of common sense. It seems fanciful to think that a bird is a dinosaur, but that is literally true.”  –Kenneth Lacovara

In this episode of Deviate, Rolf and Kenneth discuss why dinosaurs matter, especially for little kids (5:00); how we have come to learn what we know about dinosaurs (23:00); the “butterfly effect,” and how we use the ancient past to predict the future (35:00); the distinctions between the dinosaurs, and what field-work looks like (42:00); and myths about dinosaurs (53:00).

Kenneth Lacovara (@kenlacovara) is a paleontologist and geologist. He is a professor at Rowan University and fellow at the Explorers Club where he received the Explorers Club Medal, the highest honor bestowed by The Explorers Club. He is the author of the book Why Dinosaurs Matter, which is based on his TED Talk, “Hunting for dinosaurs showed me our place in the universe.”
