Huliuhe 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, 113.8° E)

• coordinate estimated from map

When: Huliuhe Formation, Early/Lower Pliocene (5.3 - 3.6 Ma)

• The age of Lower Pliocene was newly proposed.

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; nodular, pebbly, volcaniclastic, red, calcareous, cherty/siliceous claystone

• Fossil fresh water fishes and fresh water mollusca show a water bearing environment.

•The 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.

• Mainly erimson clay containing breccia of flints, and various igneous rocks usually deeply weathered. Gravels generally 1-2 cm and occasionally 8 cm in diameter, scatteredly distributed. Strings of calcareous nodules varying in thickness of 5-20 cm occurring in the red clay. At the bottom of this bed are gravel lenses, rather deeply weathered and usually passing over to erimson clay. About 5 m thick. Base not exposed.

Size class: macrofossils
