The fossils of prehistoric animals during the past 7-12 million years ago can be found entombed in the sediments, including extinct elephants, rhinos, three-toed horses, giraffe-like camels, saber-toothed cats, and bone-crushing dogs. There are also fascinating small creatures such as ancestral skunks, alligator lizards, and shrews.
