Miaobanpo (fossil) Quarry, Kaili Biota, Balang (Cambrian of China)

Where: Guizhou, China (26.7° N, 108.7° E: paleocoordinates 28.0° N, 154.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

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

• mid-third of the Lower to basal Middle Cambrian Kaili Formation. Most of the material comes from the interval 30 to 40 m above the base of the formation, which is considered lower Middle Cambrian.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; black, gray, green shale and siltstone

• Deposition is interpreted to be between 150 to 200 m water depth along the outer shelf to upper slope of the Jiangnan Slope belt on the eastern margin of the South China (Yangtze) Platform (Lin et al., 2008).
• These deeper water sediments are primarily black to greenish black, shale to silt-sized siliciclastics. Bedding in the form of fine laminae is mostly from suspension obrution sedimentation. ... Disruption of sedimentation on any scale is rare with an almost total lack of bioturbation. There is little evidence for unidirectional flow, but some levels show alignment of equal sized specimens resting on current-swept surfaces.

Size class: macrofossils

Preservation: mold/impression

Collection methods: All specimens are reposited in the collections of the Museum of Paleontology, Guizhou University, Guiyang, China
