What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus — a 77-million-year-old sauropod that was as tall as a house and as heavy as a jumbo jet — and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth’s geological history and contemplate our place in deep time.
