| Conodonts (greatly magnified) that technicians--with permission from the National Park Service--dissolved out of the Lower Silurian section of the Lower Silurian to Lower Devonian Hidden Valley Dolomite at its type locality in Hidden Valley, just south of Lost Burro Gap in Death Valley National Park, Inyo County, California. Conodonts are minute structures--unrelated to modern jaws and teeth--that served as a unique feeding apparatus in an extinct lamprey eel-like organism.
