RANCHO PALOS VERDES (CBSLA.com) — Rescue crews Friday recovered what officials are calling the oldest victim in history.

L.A.’s Natural History Museum has asked the L.A. Sheriff’s Department Search and Rescue team for help recovering an estimated 12- to 15-million-year-old fossil contained on a rock in Rancho Palos Verdes, authorities said.

The fossil, located on a hillside at 4687 Browndeer Lane in Rancho Palos Verdes, is reportedly that of a rare baleen whale. There are only a handful of such fossils in existence, according to Montrose Search and Rescue Reserve Chief Mike Leum.

Also known as whalebone whales, baleen whales are some of the world’s largest animals and are characterized by having plates for filtering food from water, rather than teeth like in the toothed whales.

Crews comprised entirely of volunteers worked most of the day to extract the 1,000-pound specimen out of a hole and then roll it up a steep
hillside on a customized cart and onto a waiting truck, according to Leum.

The residence is located approximately three miles inland from the Rancho Palos Verdes shoreline.
