Zhixin Forest Farm (Cretaceous of China)

Where: Jilin, China (42.7° N, 129.6° E)

• Paleocoordinates: 43.2° N, 140.1° E (Wright 2013)

• coordinate estimated from map

• local area-level geographic resolution

When: Dalazi Formation, Aptian (125.0 - 113.0 Ma)

• "Bed 7" of synthetic section. Aptian age based on angiosperms (Tao and Zhang, 1990). Other papers have assigned an Albian age based on pollen and plants (Yu and Miao, 1983; Zhang, 1986).
