Saint-Jacques (layer D1 of D-block) (Eocene of China)

Also known as Saint Jacques

Where: Nei Mongol, China (40.3° N, 107.1° E: paleocoordinates 41.1° N, 102.1° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Late/Upper Eocene (37.2 - 33.9 Ma)

• "During the recent fieldwork, relatively numerous faults have been recognized in the Saint Jacques area, which cut the Paleogene sediments into a number of blocks of various sizes. To avoid mixture of fossils collected from different horizons due to miscorrelation between different blocks, and for the sake of convenience, we labeled these blocks from A-block to W-block,and subdivided the strata of each block in its own sequence"

•middle part of the layer D1 of D-block

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; silty mudstone

• brownish red beds of silty mudstone

Size class: macrofossils
