Not long ago, I uploaded a new page, entitled Fossil Plants, Insects And Frogs In The Vicinity Of Virginia City, Nevada over at http://inyo3.coffeecup.com/coalvalley/c ... ssils.html.
Contains a detailed text, with on-site images and photographs of fossils.
Situated not far from Virginia City and the Comstock Lode, a regional badlands area of predominantly lacustrine diatomaceous sedimentary accumulations--which contain prolific quantitieas of the aquatic, microscopic single-celled photosynthesizing diatom species Melosira granulata--with subordinant siliceous shales and volcanic constituents, produces a bonanza of late middle Miocene fossil material, including: deciduous and evergreen leaves; gymospermous seeds, leafy twigs, needles, needles, fascicles, cones and cone scales; diptera and hymenoptera insects, primarily (flies, gnats, midges and ants, for example); and skeletal elements (including complete skeletons) of a frog that resembles in general morhological aspect two modern amphibians--the Northern leapard frog, and the California Red-legged frog (the latter of course has been extirpated from roughly Los Angeles south to the northern Baja peninsula).
