• turquoise pseudomorph after fossil bone - Nevada

    Turquoise – Natural, Specimen, Blue

    Occasionally, turquoise replaces fossilized bones and forms pseudomorphs — an atom-by-atom replacement of one mineral with another without changing its external form — like this specimen found in the Potosi Mountain area in Nevada. The complete jaw of a rodent turned into turquoise after copper-rich solutions flowed into the fossil bed. © Rob Lavinsky, www.iRocks.com. Used with permission.
