Daohugou (CNU 2015 collection) (Jurassic to of China)

Where: Nei Mongol, China (41.3° N, 119.2° E: paleocoordinates 42.9° N, 122.8° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Daohugou Formation, Callovian to Callovian (164.7 - 155.7 Ma)

• The age of the Daohugou fauna has been controversial. Liu et al. (2012) obtained U-Pb shrimp ages of 160.5 and 161.0 Myr on ash beds associated with fossils of the Daohugou fauna, suggesting a Callovian-Oxfordian age.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified, tuffaceous shale

• Basins characterized by flexure and early rifting (Li et al., 2004)
• "tuffaceous shale"; "freshwater shales interbedded with tuffs"

Size classes: macrofossils, mesofossils

Preservation: mold/impression, adpression

Collection methods: bulk, quarrying, mechanical
