The celebrated lower Cambrian Chengjiang biota of Yunnan Province, China, represents one of the most significant ever paleontological. Description. 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.

Beautifully illustrated, highly readable. To see a cihna of images fr The Chengjiang biota is one of the most remarkable fossildiscoveries ever made. Fossils are found in thin layers less than an inch thick. The sediments of Chengjiang provide what are currently the oldest known fossil chordates, the phylum to which all vertebrates belong. Another flssils places them with the Urochordates based on putative affinity with the Phylum Chordata.
Like the younger Burgess Shale fossils, the paleo-environment enabled preservation of non-mineralized, soft body parts.
Chengjiang Fossil Site – UNESCO World Heritage Centre
Since then, the locality has cxmbrian intensively studied by scientists throughout the world, yielding a constant flow of new discoveries and triggering an extensive scientific debate surrounding the interpretation of discoveries.
This special preservation has produced fossils of rare beauty; they are also of outstanding scientific importance as sources of evidence about the origins of animal groups that have sustained global biodiversity to the present day. Other mechanisms are theorized to have contributed to the Cambrian explosion, such as a cooling of the Earth and an increase in calcium in marine environments.
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 comprehensive overview of the fauna.
