Mu-42, Muhua Section (Carboniferous of China)

Also known as Mu-42, Muhua Section, Muhua Fm, Guizhou Province, China

Where: Guizhou, China (25.8° N, 106.4° E: paleocoordinates 7.3° S, 102.4° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Muhua Formation, Tournaisian (358.9 - 346.7 Ma)

• "The conodonts and ostracodes suggest a late Tournaisian age for the upper part of the Muhua Formation"

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal; lithified, lenticular limestone

• "The ostracode assemblage from sample Mu-42 clearly represents the'Eifelian ecotype' of Becker (in Bandel & Becker 1975). This ecotype is characteristic of high-energy paleoenvironments. The ostracode assemblage from the studied interval is similar in generic composition to marine near-shore to shallow off-shore ostracode assemblages described by Bless (1983) from the Late Devonian-Early Carboniferous of Europe."
• "The described ostracode assemblage os from a detrital limestone lense (sample Mu-42) in the upper part of the Muhua Formation."

Size classes: macrofossils, mesofossils, microfossils

Preservation: replaced with silica

Collection methods: bulk, chemical,

• Collection was prepared by dissolution with formic acid.

•Material reposited in the Institute of Paleobiology PAN, Warsaw (abbreviated ZPAL).
