Bull Run Basin Fossil Plant Locality

A paleobotany enthusiast searches for fossil remains. Here, the view is looking essentially due north from a fossil plant locality in the upper Eocene Chicken Creek Formation, Bull Run Basin, Nevada. The extremely fine-grained, dark-greenish shales here yield many excellently preserved 37 million-year-old conifer remains, including the winged seeds and needles of spruce, fir, pine, larch, hemlock and cypress.
