Zhangheotherium type, Jianshangou Valley (Cretaceous to of China)

Where: Liaoning, China (41.7° N, 121.0° E: paleocoordinates 44.4° N, 122.8° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Jianshangou Member (Yixian Formation), Late/Upper Barremian to Late/Upper Barremian (130.0 - 122.5 Ma)

• Beds are either of latest Jurassic age or near J-K transition. Early K age suggested by invertebrate faunal correlation and supported by a radiometric date, which authors suggest should be regarded as upper age limit.

Environment/lithology: lacustrine; shale

• Jianshangou Beds, consisting primarily of shales, are the lowest lacustrine intercalation in the neutro-basic volcanic beds of the Yixian Formation.

Size class: macrofossils

Reposited in the IVPP
