An international research team that includes Davorka Radovči?, Croatian Natural History Museum, curator, and David Frayer, University of Kansas, professor emeritus of anthropology, discovered a limestone rock recovered from the Krapina Neanderthal site didn't belong in the cave and was evidence a Neanderthal collected it 130,000 years ago.
