Xiaerhete (Eocene of China)

Also known as IVPP locality XJ201009

Where: Xinjiang, China (47.5° N, 85.5° E: paleocoordinates 48.7° N, 81.4° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Irtysh River Formation, Priabonian (38.0 - 33.9 Ma)

• "early Late Eocene" age suggested by mammalian fauna

Environment/lithology: fluvial-lacustrine; mudstone and siltstone

• At its type section about 80 km northeast of the Xiaerhete locality, the Irtysh

•layers and dark brown ferruginous layers. At the Xiaerhete locality, the sediments have similar

•crack layers and ferruginous layers, but the color is slightly less variegated
