Meet the walrus-whale, the extinct species of ancient whale, that looked a little like a cross between a dolphin and a walrus, and once roamed the oceans. Oh, for a time-traveling, whale-watching expedition!
Today, we hosted a Q&A with marine paleontologist Nick Pyenson who joined us to tell us more about the behind the scenes work of solving the mystery of just what caused the mass die-off in a five-million-year-old whale graveyard he and his team recently uncovered. "If you went on a whale watch in the late Miocene off the coast of Chile," Pyenson told us, "you would see some of the familiar (big rorquals, dolphins) and then a bit of the exotic, extinct species (walrus-whales, gnarly sperm whales). This site is really an ecological snapshot."
