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.
An aerial survey shows that Australia’s Great Barrier Reef is 95 percent bleached, and half of it is expected to die in the next month.
