Tsagan Hushu [Naran Bulak Fm.] [PMPE] (Paleocene of Mongolia)

Also known as Tsagan Khushu; Tsagan-Khushu

Where: Omnogov, Mongolia (43.5° N, 100.4° E: paleocoordinates 43.2° N, 91.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Zhigden Member (Naran Bulak Formation), Late/Upper Paleocene (58.7 - 55.8 Ma)

• Zhigden Member also spelt as Zhygden Member

•Note that the avian material (and thus possibly some of the mammalian material) is collected from a mixed assemblage of the Naran and Zhygden Members - both are Late Paleocene (Kurochkin and Dyke 2010)

• formation-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils

Collected by PMPE III in 1965

• This area originally collected by the Polish-Mongolian expeditions, and subsequently by teams from PIN.
