Also known as Yudu Basin

Where: Jiangxi, China (26.0° N, 115.4° E: paleocoordinates 26.1° N, 109.1° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Hekou Formation, Maastrichtian (72.1 - 66.0 Ma)

• "Due to the indistinct stratigraphic boundary within Guifeng group in Yudu district, the three formations (Hekou, Tangbian and Lianhe formations) are merged into one formation called Hekou Formation according to the current regional geological survey of the Yudu district. Therefore, the Upper Cretaceous strata of dinosaur-egg-bearing locality include the Maodian, Zhoutian and Hekou formations. The dinosaur eggs presented here are preserved in the uppermost part of the Hekou Formation (Maastrichtian)"

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; pebbly, red sandstone

Size class: macrofossils

Collection methods: surface (in situ),
