| An extinct tabulate coral called Halysites observed in the Lower Silurian section of the Lower Silurian to Lower Devonian Hidden Valley Dolomite in the vicinity of Lost Burro Gap in Death Valley National Park, Inyo County, California; originally photographed with a Nikon 35mm camera, then digitally remastered--and eventually edited and processed with photoshop (creating the black background, for one). |
