Wuding village, Wulongqing Fm, Canglangpuan, Cambrian Series 2 (Cambrian of China)

Where: Yunnan, China (25.6° N, 102.3° E: paleocoordinates 34.0° N, 160.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Wulongqing Formation, Botomian (516.0 - 512.9 Ma)

• Canglangpuan Stage, Cambrian

•Series 2

Environment/lithology: offshore; lithified, green, yellow mudstone

• All priapulid fossils are found in yellowish to greenish mudstone of the Wulongqing Formation. The mudstone layers normally show sharp and erosive bases and are fining upwards, ranging from 0.5 cm to 2 cm in thickness. Multiple graded silt-mud couplets are commonly observed. Complete and articulated palaeoscolecidans are mostly preserved in the layers with low-grade or no bioturbation. The living environment of the Guanshan Biota was reconstructed as a storm-dominated offshore transition, between fair-weather wave base and storm wave base, and within the photic zone, 40–50 m in depth
• Yellowish to greenish mudstone.

Size classes: macrofossils, mesofossils
