Tar Noir: Paleoforensics at the La Brea Tar Pits

\tThe La Brea Tar Pits are  world-renowned fossil sites for good reason—they're the mass graves of thousands of Ice Age creatures, each with a story to tell. Researchers at the nearby Page Museum clean the asphalt from the fossil remains, and using paleoforensics, recount the grim details of their deaths. In the process, clues emerge about what life was like in prehistoric Los Angeles.
