Where: Nye County, Nevada (38.9° N, 117.6° W: paleocoordinates 15.7° N, 53.8° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Luning Formation, Norian (228.0 - 208.5 Ma)
• The Luning Formation is a remnant of a tectonically dismembered Lower Mesozoic carbonate platform complex exposed in scattered ranges throughout west-central Nevada. It rests unconformably upon different, often unamed, Late Paleozoic and Triassic units in each outcrop, but is regoinally overlain by the Upper Triassic through Lower Jurassic Gabbs and Sunrise Formations.
