The Maotianshan Shales are a series of Early Cambrian deposits in the Chiungchussu Formation,
famous for
their Konservat Lagerstätten, deposits known for the exceptional preservation of fossilized organisms or traces
. The Maotianshan Shales form one of some forty Cambrian fossil locations worldwide exhibiting exquisite
preservation of rarely preserved, non-mineralized soft tissue, comparable to the fossils of the Burgess Shale.
They take their name from Maotianshan Hill in Chengjiang County, Yunnan Province, China.
The most famous assemblage of organisms are referred to as the Chengjiang biota for the multiple scattered fossil sites
in Chengjiang. The age of the Chengjiang Lagerstätte is locally termed Qiongzhusian, a stage correlated to the late
Atdabanian Stage in Siberian sequences of the middle of the Early Cambrian. The shales date to ≤518 million years ago.
The shales also contain the slightly younger Guanshan biota from Malong District in Yunnan.
