In this video from the NOVA series, Decoding Neanderthals, scientist Michael Walker leads his team into a deep shaft, where they find the bones of Neanderthals. Based on the bodies' positions, he thinks that rather than dying in an accident, they probably were actually buried. Also, a panther's paws were found at the site. Since there is no sign of an animal disturbing the bones, it is possible that the Neanderthals killed the panther and kept the paws as a trophy.
