La Brea: In the La Brea Tar Pits more than one million bones have been taken from the dried oil since 1906. 231 vertebrate species, 234 invertebrate species, and 159 plant species have been identified. The most frequent large mammal found in the La Brea Tar Pits is the dire wolf. This is one of the most famous prehistoric carnivores that lived in the Pleistocene epoch. Fossils from saber-toothed cats and coyotes are also common. More fossils are being discovered by excavation projects.
