Dr. Daniel C. Fisher, guest curator for the museum's current exhibit, "Titans of the Ice Age: Mammoths & Mastodons," gives a talk about the 40,000-year-old baby wooly mammoth, "Lyuba," featured in the exhibit. It was found in Siberia in 2007 by a family of reindeer herders, and Dr. Fisher had the opportunity to study her. He'll share what he learned about her life and the prehistoric time when she lived.
