This book record one of the most amazing finds in the
20th century the find of the Chengjiang fauna in true and detail. It has
more than 200 kinds firs hand precious pictures of fossil, and provides
their Chinese names, Latin names, Locality. It reappears the wonderful
spectacles about the life of marine animals and the original characteristics
of the existing living beings on the earth from 530 million years ago.
It provides precious materials for enriching the theory of evolution.
The Cambrian represents the beginning of a long sequence
of geological time known collectively as the Phanerozoic. This term is
composed of the Greek words planners, meaning visible, obvious, and Zion,
animal. This was to stress the difference from the older, once seemingly
unfossiliferous Precambrian rocks, the Cryptozoic.
Although both microfossils and macrofossils are now known
from Precambrian rocks, particularly from late Precambrian, there is the
striking difference in numbers and types of fossils with those in the
Phanerozoic. However, the situation varies in detail. In some areas Cambrian
rocks may contain many fossils, whereas in others there are sandstone's
or other rocks that are commonly poorly fossiliferous. In addition, different
fossils occur in the Cambian in different parts of the world, which makes
it difficult when making comparisons to know if we are talking about strata
of exactly the same age.
