LA Tar Pits

Volunteer Meganne Macias works on the giant pelvis of a well preserved Colombian mammoth fossil named 'Zed' by laboratory workers at the Page Museum at the La Brea Tar Pits in Los Angeles on Wednesday Feb. 18, 2009. Researchers discovered 16 fossil deposits under an old parking lot next to the tar pits in 2006 and began sifting through them last summer. The mammoth remains, including 10-foot-long tusks, were in an ancient riverbed near the fossil cache.
