The Chengjiang Deposits of China
Many Burgess Shale-type fossils have
also been found in Cambrian deposits near
the town of Chengjiang in Yunnan
Province of China.
The Chengjiang mud beds were found to be
lower Cambrian in age; therefore about 15
million years older
than the Burgess Shale deposits. The picture to the
right shows researchers from the Nanjing Institute of Geology
and Paleontology excavating the site. Over
10,000 specimens have been recovered thus far.
The following photos include three of the many species found at the Chengjiang site. To the left is Microdictyon and in the center is a bivalved brachiopod. The plant-like Dinomischus to the right, is also found in the Burgess Shale. The worldwide distribution of some taxa indicates that the Burgess fauna was not a geographically isolated phenomenon.
