LOST BEASTS OF THE ICE AGE follows a team of international scientists including Dr. Tori Herridge, Paleontologist at the Natural History Museum in London, and Harvard Medical School Geneticist Professor George Church, on an expedition to seek out well-preserved remains of woolly mammoths, woolly rhino, wolves and cave lions that once roamed Siberia. Working in tunnels dug by locals on the hunt for valuable giant mammoth tusks, their findings may reveal extraordinary new evidence that could lead us closer to answering one of the biggest mysteries of the ice age – what caused the woolly mammoth to go extinct?
