Also known as SSF 26.1

Where: Xinjiang, China (40.5° N, 79.1° E: paleocoordinates 11.6° S, 135.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Yurtus Formation, Tommotian to Tommotian (525.5 - 516.0 Ma)

• LITHOSTRATIGRAPHY: From the Yurtus Fm, which unconformably overlies the Qigebulak Fm and is unconformably overlain by the Xiaoerbulak Fm. AGE: Most likely age is late Tommotian to early Atdabanian, on the basis of various biostratigraphic indicators. STRATIGRAPHIC POSITION: From multiple beds within local section, mostly concentrated towards top of the section.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, phosphatic limestone

Preservation: cast, replaced with phosphate
