Yuxian Formation, Huabaogou, Xiyaozhitou, Yu county (Pliocene of China)

Also known as Hipparion Red Clay

Where: Hebei, China (39.8° N, 114.6° E: paleocoordinates 39.8° N, 114.0° E)

• coordinate estimated from map

When: Yuxian Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)

• The age of Upper Pliocene is newly proposed.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; red claystone and lenticular sandstone

• Horses, giraffes and gazelles resemble partly the present tropical-subtropical prairie and savanna fauna of Africa, so that the presence of the so-called "Hongya Glacial Epoch" cannot be verified.
• Red clay with sandy lenses in the upper part and calcareous nodular gravels at the base.

Size class: macrofossils
