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 (166.1 - 157.3 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.
