Sai-Sagul, Shurab III (PIN collection 2068) (Jurassic of Kyrgyzstan)

Where: Batken, Kyrgyzstan (40.0° N, 70.7° E: paleocoordinates 41.7° N, 76.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Sagul Formation, Toarcian (182.7 - 174.1 Ma)

• Formation thought to be late Early Jurassic, based on the flora (Aliev et al., 1981).

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - small; lithified siliciclastic sediments

• Based on the Sinichenkova and Zherikhin (l.c.) reconstruction these assemblages were restricted to the shallow small oxbow lakes with abundant allochthonous detritus in river valleys. Mesozoic intramontane Tien Shan basins formed by reactivation during Qiangtang collision.

Size class: macrofossils

Preservation: mold/impression

Collected by Chastikova in 1957; reposited in the PIN
