| Here are three different views of the same coral specimen from the lower Silurian to lower Devonian Vaughn Gulch Limestone, Mazourka Canyon, Inyo County, California. Scientific name is Kyphophyllum nevadensis. At top is the exterior perspective, as observed when found at the fossil locality. Bottom two images are transverse thin sections of the specimen seen at top, revealing several of the individual corallites that comprise the coral colony. The photographs came from a specific public domain document. |
