Miaobanpo section (Orytocephalus indicus zone) - Kaili Fm (Cambrian of China)

Where: Guizhou, China (27.0° N, 107.0° E)

• Paleocoordinates: 6.1° S, 79.8° E (Wright 2013)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Oryctocephalus indicus trilobite zone, Kaili Formation, Taijangian (509.0 - 504.5 Ma)

• STRATIGRAPHIC RELATIONS: From the Kaili Fm, which overlies the Tsinghsutung Fm (Duyunian), and is overlain by the Jialao Fm (Taijiangian). THICKNESS: From succession with formation of c. 160 m thick. AGE: Duyunian stage, upper Early Cambrian. STRATIGRAPHIC POSITION: From beds 10-22, which equate to the Oryctocephalus indicus zone of the lower Kaili Formation.

• member-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, gray, green, silty mudstone

• ENVIRONMENT: Offshore carbonate setting. Low energy, turbidity currents, and suspension sediments in outer shelf setting, in depths of 150-200 m. Some evidence for current alignment consistent with turbidites, but commonly orientation suggests quiet water and suspension sedimentation.
• SPECIFIC LITHOLOGY: Grayish-green silty, calcareous mudstones intercalated with dark gray interlayered mudstones. LITHIFICATION: Lithified on the basis of figured specimens and taphonomy.

Size class: macrofossils

Preservation: cast, mold/impression, soft parts
