Haikou [Yuanshan Fm (formerly Qiongzhusi)] (Cambrian of China)
Also known as Chengjiang biota; Jingmacun, Kunming
Where: Yunnan, China (24.8° N, 102.6° E: paleocoordinates 35.1° N, 161.1° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Eoredlichia trilobite zone, Yuanshan Formation, Atdabanian (521.0 - 516.0 Ma)
• LITHOSTRATIGRAPHY: Formerly from the Yuanshan Mbr, Qiongzhusi Fm. Yuanshan is raised to formation rank in recent publications (Steiner 2005, 2007). Wade-Giles romanization of Qiongzhusi is Chiungchussu. AGE: Eoredlichia Zone. Refined to Atdabanian by A. Hendy (2/2009)
• group of beds-level stratigraphic resolution
Environment/lithology: marine; lithified, gray, green, yellow, carbonaceous mudstone
• "benthic sediment flows... are believed to have been the the principal method of burial" (Shu et al. 1999b)
•"presence of agglutinated quartz grains, substantially coarser than the surrounding matrix... suggests... that the animal inhabited a higher-energy, sandy sea floor and was transported" (Shu et al. 2001)
• LITHOLOGY: Dark grey-green (yellow, when weathered), finely laminated mudstones, containing organic hash in great quantity. LITHIFICATION: Lithified, on the basis of figures.
Size class: macrofossils
Preservation: adpression, soft parts
Collection methods: surface (in situ), hydrochloric,
• COLLECTOR: Multiple collectors. REPOSITORY: Not stated in text.
