EDIACARAN-CAMBRIAN BOUNDARY STRATIGRAPHY AT MEISHUCUN, JINNING COUNTY, AND FOSSIL QUARRIES OF THE EARLY CAMBRIAN CHENGJIANG BIOTA NEAR HAIKOU, KUNMING CITY, YUNNAN, CHINA

摘要

The Meishucun area, Jinning County, located west of Dianchi Lake, exposes an excellent succession of Ediacaran (Neoproterozoic) and Lower Cambrian strata (Fig. 1). The Ediacaran-Cambrian stratigraphy near Meishucun Village, has long been considered one of the best Precambrian-Cambrian boundary intervals globally (Luo et al., 1984, 1994). Present in this interval are some of the earliest trilobites and subtrilobitic small shelly fossils (SSFs). The village of Meishucun is about 71 km from Kunming, and is reached by driving from Kunming along the highway on the east side of Dianchi Lake.
