The celebrated lower Cambrian Chengjiang biota of Yunnan Province, China, represents one of the most significant ever paleontological. 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 The Chengjiang fossils comprise the oldest diverse metazoan assemblage.

Chengjiang is one of some 40 known Cambrian localities that exhibit Burgess Shale-like, exquisite preservation fowsils soft tissues. Much of the scientific documentation of the Chengjiang biota is in Chinese, and the first edition of this book was the first in English to provide fossil enthusiasts with a chenggjiang overview of the fauna.

Cambtian many fossil deposits, those of Chengjiang and the younger Burgess Shale show exceptional preservation of nonmineralized body chna and internal soft tissues, affording us far more information than could be gleaned from preservation of hard skeletal elements alone.
