The new world of fossil biology

Studying fossils offers a window into the ancient world. Dale E. Greenwalt is resident research associate at the Smithsonian Institution’s National Museum of Natural History, where he curates the Kishenehn Formation fossil insect collection. He joins host Krys Boyd to discuss how the field of paleobiology is opening up new avenues for what we know about ancient life, and the fascinating findings it’s already yielded. His book is “Remnants of Ancient Life: The New Science of Old Fossils.”
