| This is a different view of all but one of the fossil horse teeth in the previous image (the tooth at lower right in the previous picture does not appear in this second image). Teeth and miscenllaneous bones of the extinct singe-toed horse Equus simplicidens are by far the most common vertebrate fossils encountered in the Coso Formation badlands, Coso Range, Inyo County, California. Specimens are roughly three million years old. For scale, the horse jaw segment at upper middle is 70 millimeters long. |
