Where: Gansu, China (40.1° N, 97.4° E: paleocoordinates 39.5° N, 98.0° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Chijinbao Formation, Aptian (125.0 - 113.0 Ma)
• The combined biostratigraphic and numerical age data suggest that the Changma Basin began accumulating sediment no older than Hauterivian (based on pollen records), is older than the Coniacian (based on the crosscutting dykes), but is likely Barremian to Aptian based on the similarities to the Jehol biota (Suarez et al., 2013)
