Ikh Argalatyn Nuruu, IKH-A/1-4 (Oligocene of Mongolia)

Also known as Valley of Lakes

Where: Övörkhangai, Mongolia (45.3° N, 102.1° E: paleocoordinates 46.3° N, 98.2° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: B mammal zone, Hsanda Gol Formation, Early/Lower Oligocene (33.9 - 28.4 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; red, silty mudstone

• The fines of the Hsanda Gol Fm. are interpreted as eolian dust and playa sediments, deposited on an arid plain (Höck et al., 1999).

• The Hsanda Gol Fm. mainly consists of "brick red" poorly sorted mudstones (Höck et al., 1999).

Size class: mesofossils

Collected by joint Austrian-Mongolian project; reposited in the NHMW

Collection methods: sieve
