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.
