It might not look like much from the outside, but an unassuming warehouse in Maryland is home to the biggest collection of whale bones in the world. Some of the bones at the Smithsonian's Museum Support Center (MSC) hold their own records, too—as the the Smithsonian's Nick Pyenson explains to NPR’s Madeline Sofia, the MSC's blue whale jawbone is the largest bone in the world.

Pyenson, curator of fossil marine mammals for the Smithsonian National Museum of Natural History, is a paleobiologist who describes himself as a "marine mammal detective through geologic time"—an investigator who works to uncover the ways that whales and other creatures serve as fabulous clues to the history of evolution, as well as offering information about what's coming next.
