Bull Run Basin Fossil Insect And Plant Locality

Paleobotany and paleoentomology adventurers at an insect and plant locality in the upper Eocene Chicken Creek Formation, Bull Run, Nevada. The view looks northward from the 37 million-year-old fossil-bearing site, which occurs in the pale-greenish to tan shales that erode from the roadcut (right side of image). Here can be found rather common fly larvae exoskeletons, probably similar to specimens that occur in the famous Eocene Green River Formation of Wyoming, eastern Utah and Colorado--plus conifer winged seeds.
