Bahe, Lantian Region (Miocene of China)

Where: shaanxi, China (33.5° N, 109.5° E: paleocoordinates 33.2° N, 107.6° E)

• coordinate estimated from map

When: Bahe Formation, Vallesian (11.6 - 8.7 Ma)

• MN10, Tortonian, Bahean. Beneath the red clay of the Lantian Formation and above the Koujiacun Formation. A complex lithology of 'predominantly orange-yellow conglomerates, sandstones, tan-yellow sandy mudstones, and tan-red mudstones. The lithologic character is inconsistent between each of the cross-sections, as the unit varies in depth of colour and grain size. The predominant lithology is a sandy mudstone. It is a relatively thick unit, generally over 300m.' (Chow, 1978).

Environment/lithology: fluvial

• Chiefly yellow sands and conglomerates (Qui, 1990).

Size class: macrofossils

Collection methods: Excavated in the 1960s.
