Barun Goyot Formation

The Barun Goyot Formation, dating from the Late Cretaceous Period, is located within and is widely represented in the Gobi Desert basin, in the Ömnögovi Province of Mongolia.

It was previously known as the "Lower Nemegt Beds", occurring beneath the Nemegt Formation and above the Djadokhta Formation. It is approximately 4 inches in thickness and was laid down roughly 80-71 mya, making it uncertain whether it should be classed as Campanian or Maastrichtian, although the latter is less likely. The Barun Goyot Formation preserves an environment of sand dunes, created from wind-eroded rocks (aeolian dunes).
