Shangyong village (Eocene of China)

Where: Yunnan, China (21.2° N, 101.7° E: paleocoordinates 16.1° N, 95.7° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ypresian (56.0 - 47.8 Ma)

• The true Mengyejing Formation is an early Late Cretaceous stratum. However, the "Mengyejing Formation" near Shangyong Village may belong to an undefined stratum. An early Eocene age (Ypresian) is more convincing on the basis of the study of the conchostracan Paraleptestheria menglaensis (Chen and Shen, 1980; Shen et al., 2006).

Environment/lithology: terrestrial; lithified, yellow mudstone

• Yellow mudstone

Size classes: macrofossils, mesofossils

Preservation: mold/impression

Taxonomic list

• "The original label noted that the specimens came from Mengyejing Formation, associated with fossil conchostracans, ostracods, spores, and pollens. Fossil insects are frequent in the yellowish mudstone and represented by mostly isolated fragments such as beetle elytra" Lin et al., 2010
