We have over 150,000 catalogued specimens of fossil vertebrates, ranging in size from the tiny teeth of fish, bats, shrews, and rodents, to large whales. Our collections are primarily from California, the southwestern portion of the United States, and the northwestern portion of Mexico. They include representatives of every class of fossil vertebrates, but fossil mammals from the Cenozoic (the last 65 million years) form the bulk of the collections. Because of the extensive exposures of marine rocks in Southern California, our collections also include large and diverse holdings of fishes, sharks, whales, pinnipeds, and other marine vertebrates. Opened in 2010, our new Age of Mammals hall exhibits many of our most complete fossil mammal skeletons.
