Liushu Formation
Liushu Formation (China)

The Liushu Formation is a geological formation in Gansu province, China that spans up to 100 m thick and is widely distributed within the Linxia Basin, with a paleomagnetic age between 11 and 6.4 mya (Upper/Late Miocene).

Geology

The formation is divided into three parts representing three different ages, generally referred to as the "upper part" (youngest, at 6-7 mya), the "middle part" (intermediate, at 9 to 7.6 mya, also known as the Dashengou Fauna), and the "lower part" (oldest).[1][2]

Perissodactyla

The Liushu formation displays a lineage of Elasmotheriine rhinoceros throughout its stratigraphy. Iranotherium is restricted to the middle part of the formation but remains absent in the overlying layers, the only Elasmotheriine that can be found in the upper layers is Sinotherium.
