Lower Ordovician Fillmore Formation

Millard County, Utah

A roadcut that exposes the lower Ordovician Fillmore Formation (second-oldest member of the Pogonip Group) in Millard County, Utah, a number of miles east of the eastern border of White Pine County, Nevada. The Fillmore Formation is the second-oldest geologic rock unit of the Pogonip Group, yielding such invertebrate animal groups as graptolites, trilobites, brachiopods, conodonts, gastropods, echinoderms, cephalopods, and occasional lenticular algae-sponge patch reefs. A Google Earth street car perspective that I edited and processed through photoshop.
