Shunkht badlands with redbeds (HMNS-GIN) ( of Mongolia)

Where: South Gobi Aimag, Mongolia (44.1° N, 106.9° E: paleocoordinates 45.3° N, 102.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Mogotuin Suite Group, Cenozoic (66.0 - 0.0 Ma)

• Based on the mammalian fossil assemblage, the red beds are con

•sidered to be Cenozoic. More detail and longer prospecting work for fossils in the area will provide rich mammalian fossil specimens. The application of magnetostratigraphy to the red beds with thickness over 30 meter will also give reasonable dating results of the fossiliferous red beds.

Environment/lithology: terrestrial; red mudstone and fine-grained sandstone

• The red beds consist of thick mudstone, intercalating sandstone and conglomerate layers. From the mudstone and fine sandstone, we found mammalian fossils. Caliche is abundantly developed in the mudstone.

Size class: macrofossils
