Where: Xinjiang, China (41.0° N, 84.0° E: paleocoordinates 39.3° N, 76.4° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Upper Member (Qimugen Formation), Early/Lower Eocene (55.8 - 48.6 Ma)
• STRATIGRAPHIC RELATIONS: From the upper member of the Qimugen Fm, which overlies the lower member of the Qimugen Fm (Late Paleocene) and is overlain by the Kalatar Fm (lower Middle Eocene). AGE: Early Eocene. Justification not stated, but presumably through macrofossil and microfossil biostratigraphy. Pollen present. STRATIGRAPHIC POSITION: From bed within middle part of the upper member of the formation.
• bed-level stratigraphic resolution
Environment/lithology: peritidal; lithified, dolomitic, shelly/skeletal limestone
Size class: macrofossils
Reposited in the NIGPAS
Collection methods: bulk,
• COLLECTOR: Not stated, but presumably X. Lan and J. M. Wei (1980's). REPOSITORY: Probably Nanjing Inst. of Geol. and Pal., Academia Sinica.
