| Here's is a small outcrop of the world-famous Middle Miocene Sharktooth Hill bone bed, exposed at a once-popular locality, called colloquially The Amphitheater in Kern County, California. The precise trend of the shark tooth-bearing horizon is marked by the prominent World War I-style entrenchment which zigzags along the hillside, from middle-upper right to upper left of the image. The view is almost due south. |
