Once in a while, scientists re-discover an unusual specimen hidden on the shelves of a museum collection. This time, they found a cast of a skull from a Southern elephant seal, Mirounga leonina, which swam upriver to Indiana over 1000 years ago. The cast had been hidden in a drawer of the fossil marine mammals collection at the Smithsonian’s National Museum of Natural History since the 1970s.
