Lower Cambrian rocks in Yunnan Province, southwestern China, contain the most significant fossil deposit anywhere on Earth - the Chengjiang Lagerstätte. Abundant and beautifully preserved fossils of nonmineralizing organisms occur in the Heilinpu Formation. They represent creatures living soon after the Cambrian Explosion, the most significant & enigmatic evolutionary event in Earth history. Chengjiang fossils were "first found" near the small city of Chengjiang in 1984. They have since been reported from numerous localities in eastern & east-central Yunnan Province.
This photo depicts the “discovery locality” of the Chengjiang Lagerstätte. This is the world-famous Maotianshan outcrop (“hat-shaped hill” / “hat-shaped mountain”) [not “Mao's tall hill”]. This was originally a hillslope exposure, but is now a roadside fossil quarry.
Locality: the outcrop is along the western side of Maotianshan, ~3.2 km east-northeast of Jiucheng & ~5.4 km east-southeast of the city of Chengjiang, in east-central Chengjiang County, far-northeastern Yuxi Prefecture, east-central Yunnan Province, southwestern China.
GPS of cut: 24° 39' 38" North, 102° 57' 56" East.
The pic above shows an exposure of structurally tilted & deeply weathered clayshales of the Heilinpu Formation at the Maanshan outcrop. Soft-bodied fossils are abundant here.
Locality: Maanshan (“Maan Hill” / “Maan Mountain”) is located ~0.8 to 0.9 km northwest of Ganhaizi & ~6.3 km due east of Chengjiang, eastern Chengjiang County, far-northeastern Yuxi Prefecture, east-central Yunnan Province, southwestern China.
GPS of cut: 24° 40' 36" North, 102° 58' 45" East.
This is the view from the Maanshan outcrop. Notice that the Chinese have terraced steep hillsides for growing food (China has tons & tons of people!).
