Also known as Yinbocun, Hongqingbaogou, Xian

Where: shaanxi, China (34.6° N, 109.4° E: paleocoordinates 35.4° N, 103.1° E)

• coordinate based on nearby landmark

When: upper Member (Honghe Formation), Eocene (56.0 - 33.9 Ma)

• 'The Honghe Formation comrpises the lowermost regional Cenozoic sediments.' 'Its principal lithologic characteristic is its interbedded purple-red mudstones, sandy mudstones, and fine sandstones with basal conglomerates. Exposures are approximately 200m thick.' The upper faunal layer is approximately 60m from the top of the section, and 'consists of interbedded purple-red sandy mudstones and sandstones.' The interbedded sandstones are approximately 9m thick, 'containing abundant sandstone concretions and mudballs. Fossils are produced from within the concretions.'

Environment/lithology: mudstone and sandstone

• 'interbedded purple-red sandy mudstones and sandstones.' The interbedded sandstones are approximately 9m thick, 'containing abundant sandstone concretions and mudballs. Fossils are produced from within the concretions.'

Size classes: macrofossils, mesofossils

Preservation: concretion
