Where: Xinjiang, China (41.0° N, 84.0° E: paleocoordinates 41.0° N, 78.0° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Wulagen Formation, Bartonian (41.3 - 38.0 Ma)
• STRATIGRAPHIC RELATIONS: From the Wulagen Fm, which overlies the Kalatar Fm (lower Middle Eocene) and is overlain by the Bashibulake Fm (Late Eocene-Early Oligocene). AGE: upper Middle Eocene. Justification not stated, but presumably through macrofossil and microfossil biostratigraphy. Pollen present. STRATIGRAPHIC POSITION: From bed within upper part of the formation.
• bed-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified, tuffaceous 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.
